[Dovecot] 9GB of messages in /tmp
by Charles Marcus 13 Jun '08

13 Jun '08

Hello, Well, I have a brain-dead user (using Thunderbird 2.0.0.14) who just won't listen when I tell them not to try to move 5000+ messages at one time (or if deleting, bypass the Trash), and they managed to royally screw up their maildirs... I have two problems... 1. The /tmp directory has 9+GB in it... can I just rm tmp/* on that directory without making this problem worse? and 2. One of the directories they were moving now has 5 copies of a whole bunch of messages... I'm very dangerous when it comes to command-line work beyond really basic stuff, and my scripting skills are less than inspiring... Is there a relatively safe command-line way of finding all messages that have more than one instance, and deleting all but the last instance? Tia... -- Best regards, Charles

[Dovecot] "Disable non webmail IMAP access" in vpopmail and Dovecot
by Alessio Cecchi 13 Jun '08

13 Jun '08

Hello, i'm using in my installation qmail+vpopmail and now I have migrated from courier-imap to dovecot. Dovecot is very much faster with large mailbox than courier-imap. But I have a problem. vpopmail has a feature that allows you to "Disable non webmail IMAP access", many webmail using imap as if they were, and they are, a client IMAP. vpopmail give me the ability to disabile IMAP, expect for 127.0.0.1, both for individual users than for single domain. So i can grant IMAP access, from remote client, only for some users but webmail access for all. Here you can read some of my messages in the vpopmail's list: http://www.mail-archive.com/vchkpw@inter7.com/msg25880.html But with dovecot this feature seems not to be compatible. A friend of the vpopmail's list sent me a patch for dovecot but I can not get it to work: >->->->->->->->->->->->->->->->->->->->->->->->->->-> Hi Alessio, i spent over 5 hours looking for a solution to this problem and i found one working for me in dovecot sources edit src/auth/passdb-vpopmail.c than add char *remotehost = net_ip2addr(&auth_request->remote_ip); auth_request_log_info(auth_request, "vpopmail", "remote ip is: %s", remotehost); before if (((vpw->pw_gid & NO_IMAP) != 0 && line than modify the condition line to look like: if (((vpw->pw_gid & NO_IMAP) != 0 && strcmp(auth_request->service, "IMAP") == 0 *&& strcmp(remotehost, "127.0.0.1") != 0*) || ((vpw->pw_gid & NO_POP) != 0 && strcmp(auth_request->service, "POP3") == 0)) { auth_request_log_info(auth_request, "vpopmail", "%s disabled", auth_request->service); password = NULL; *result_r = PASSDB_RESULT_USER_DISABLED; } else ............... this way you will preserve webmail access and cut imap from external in case -i limit is defined in vpopmail hope it helps <-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< Can someone help me in making compatible this useful feature of vpopmail with dovecot?

[Dovecot] configure error on HP-UX: C99 compatible vsnprintf() call
by Woonsan Ko 13 Jun '08

13 Jun '08

Hi All, I tried to build dovecot-1.1.rc9 on a HP-UX machine, but failed to configure with the following message: configure: error: You don't appear to have C99 compatible vsnprintf() call The environment is like the following: - command: ./configure - uname: HP-UX B.11.23 U ia64 - aCC version: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003] Also, I tried to run `./configure CC=c99' and `./configure CC="/opt/aCC/bin/aCC -Ae" also, but the result was the same. I'm not sure, but the HP C compiler does not seem to support C99 fully with vsnprintf() call. Is there any workaround for this problem? TIA, Woonsan

[Dovecot] [Patch] Fix delay on imao-append
by Bruno Prémont 13 Jun '08

13 Jun '08

Dovecot version: 1.1-rc8, 1.1-rc9 System: Linux-2.6.2x User-Agent: claws-mail-3.3 and 3.4 When appending messages (e.g. copy from mailclient local folder or second server to dovecot imap folder) dovecot answers with: <tag> OK [APPENDUID <n> <m>] Append completed\r\n This answer often reaches the client as two or more TCP packets, the client (when not using TCP_NODELAY on its socket) ACKs with some delay. When copying lots of (small) messages this delay has a very negative impact on copy time even though there are lots of network and system resources available. Sample sniffer output on client host: ... 1 0.0000 claws dovecot IMAP Request: 14639 APPEND "Test" (\Seen) {853} 2 0.0033 dovecot claws IMAP Response: +OK 3 0.0034 claws dovecot IMAP Request: <message> 4 0.0096 dovecot claws IMAP Response: 14639 5 0.0467 claws dovecot TCP 33453 > imap [ACK] 6 0.0481 dovecot claws IMAP Response: OK [APPENDUID 1204729411 2] Append Completed. 7 0.0481 claws dovecot TCP 33453 > imap [ACK] ... The delay of about 35ms between packet 4 and its ACK in packet 5 causes copies from client to server to be extremely slow. (Client and server on same 100Mb LAN, same result if client and server are on same host) The attached patch makes dovecot send the whole answer in a single packet, thus not triggering the delay issue. As far as I found out the delay is generated by Naggle algorithm, this algorithm being used by Linux TCP stack for small packets with the aim of improving payload/overhead share.

[Dovecot] How many imap processes per user
by Martijn de Munnik 13 Jun '08

13 Jun '08

Hi, I'm using dovecot for the first time on a production server (before dovecot I used bincimapd). I have a question about the number of imap (not imap-login) processes created for a user. I've seen 100+ processes for just 1 user. So far it only occurs for 1 user, other users have just 1 imap process. I now the user is using thunderbird and 2 mailclients are logged in at the same time (one workstation and one laptop). Is there an issue with dovecot/thunderbird? info@dem 28596 15780 0 10:48:41 ? 0:02 imap info@dem 28933 15780 0 10:50:57 ? 0:01 imap info@dem 25627 15780 0 10:28:55 ? 0:00 imap info@dem 28938 28933 0 - ? 0:00 <defunct> info@dem 29472 15780 0 10:54:23 ? 0:00 imap info@dem 25628 25627 0 10:28:55 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29329 29327 0 - ? 0:00 <defunct> info@dem 29805 29801 0 - ? 0:00 <defunct> info@dem 24303 24300 0 10:20:46 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29941 15780 0 10:58:09 ? 0:00 imap info@dem 28480 28477 0 - ? 0:00 <defunct> info@dem 28329 15780 0 10:46:28 ? 0:03 imap info@dem 29177 29176 0 - ? 0:00 <defunct> info@dem 28749 28748 0 - ? 0:00 <defunct> info@dem 29801 15780 0 10:56:56 ? 0:00 imap info@dem 29180 29179 0 10:52:05 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29635 15780 0 10:55:35 ? 0:00 imap info@dem 29642 29635 0 - ? 0:00 <defunct> info@dem 28477 15780 1 10:47:37 ? 0:02 imap info@dem 28200 28199 0 - ? 0:00 <defunct> info@dem 29942 29941 0 10:58:09 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 28597 28596 0 - ? 0:00 <defunct> info@dem 28330 28329 0 - ? 0:00 <defunct> info@dem 25610 25609 0 10:28:49 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 28748 15780 0 10:49:48 ? 0:02 imap info@dem 25609 15780 0 10:28:49 ? 0:00 imap info@dem 29176 15780 0 10:52:05 ? 0:01 imap info@dem 29327 15780 0 10:53:12 ? 0:01 imap info@dem 29179 15780 1 10:52:05 ? 0:05 imap info@dem 28199 15780 0 10:45:22 ? 0:03 imap info@dem 29474 29472 0 - ? 0:00 <defunct> info@dem 24300 15780 0 10:20:46 ? 0:00 imap All those processes are really slowing down the server.

[Dovecot] strange looking code and userdb errors
by Tony den Haan 13 Jun '08

13 Jun '08

hi, i'm trying to use passdb ldap and userdb prefetch, using the userdb_ prefixes in pass_attrs, and i get: passdb didn't return userdb entries looking at the code at auth/userdb-prefetch.c i see: if (auth_request->userdb_reply == NULL) { if (auth_request->auth->userdbs->next == NULL) { /* no other userdbs */ auth_request_log_error(auth_request, "prefetch", "passdb didn't return userdb entries"); } else { /* more userdbs, they may know the user */ auth_request_log_info(auth_request, "prefetch", "passdb didn't return userdb entries"); } callback(USERDB_RESULT_USER_UNKNOWN, auth_request); return; } is this really correct? if so it migth be a good idea to at least print different errors Tony

[Dovecot] auth issues on centos5 with ldap backend
by Jurvis LaSalle 13 Jun '08

13 Jun '08

Hi, We've had some issues with auth. /var/log/secure is full of 1000s of these lines: Jun 4 19:12:08 khan dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser= rhost=127.0.0.1 user=user123 Users can usually login OK with their ldap credentials, but occasionally logins slow to a crawl if not outright fail, esp people checking mail through Squirrelmail. Things get better after a dovecot restart. Googling around, I thought if we switched the order or disabled the second passdb we had configured for our dovecotadmin account, these failures would go away but that did not happen. Any thoughts or additional info I can provide? Pardon the unusual install prefix. We're trying to keep the source install separated from the ancient dovecot rpm shipped in rhel5.

[Dovecot] Antispam plugin custom behavior?
by Kyle Wheeler 12 Jun '08

12 Jun '08

Hello, I currently have a setup on my system with what I call "magic folders" to enable spam filter training. Here's how it works: 1. If you have a false-negative, put the spam into the Spam.Report folder 2. If you have a false-positive (which has all kinds of ugly spamassassin protective markup in it), put the message into the Spam.NotSpam folder Currently what happens is that a cron job comes along every five minutes and processes the messages in those folders. In the case of the NotSpam folder, it strips the message of the spamassassin markup, retrains the bayesian net, and redelivers the message (e.g. via deliver). In the case of the Report folder, the message is used to train the bayesian net (among other things) and then deleted. I'd love to be able to trigger these actions when the mail is moved, rather than have a cron job inspecting the mailboxes. I looked into the antispam plugin (http://johannes.sipsolutions.net/Projects/dovecot-antispam) which seems nice but doesn't appear sufficiently generic for my needs. What would really work is if I could get it set up such that putting a message into either of those directories is turned into piping the message to a script of my choosing (a different one for each folder). Does anyone know a good way of getting my own custom behavior in here, or is my cronjob setup probably the best way? ~Kyle -- The optimist thinks this is the best of all possible worlds. The pessimist fears it is true. -- J. Robert Oppenheimer

[Dovecot] quota-rewrite patch & userdb quota overriding
by Alan Premselaar 12 Jun '08

12 Jun '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've spent the past couple of hours trying to figure this out by checking the wiki and googling, but haven't come up with anything that works yet. I just installed dovecot 1.0.14 with the quota-rewrite (1.09) patch and i'm trying to get the quota overridden via a passwd-file type userdb. I had 1.0.13 without the new quota style patched in working but having trouble figuring this out. any help would be appreciated. prior to the quota-rewrite patch (which i installed with the hopes of using quota_warn feature) i was able to put the following line into my passwd-file userdb and it was working: alan:*:1000:1000::/home/alan::userdb_quota=maildir:storeage=2048000:ignore=Sent (which is what I wanted) but now with the new quota definition style, I'm not sure what I need to define the extra fields as. here is dovecot -n: # 1.0.14: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap imaps managesieve ssl_cert_file: /etc/pki/tls/certs/dovecot.pem ssl_key_file: /etc/pki/tls/private/dovecot.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(managesieve): no verbose_proctitle: yes mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(managesieve): ~/.dovecot.sieve auth default: ~ passdb: ~ driver: pam ~ userdb: ~ driver: passwd-file ~ args: /usr/local/etc/dovecot.passwd ~ userdb: ~ driver: passwd ~ socket: ~ type: listen ~ master: ~ path: /var/run/dovecot/auth-master ~ mode: 384 ~ user: dovecot ~ group: dovecot plugin: ~ quota_rule: *:storage=1G ~ quota_rule2: Trash:storage=100M thanks, alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhPd+cACgkQE2gsBSKjZHQNMACghSk7awVX1Aj5HVeo0KjRxyZc lT0AoLJA00SiYiefi2wNrAOt7L6N5eg4 =mA8L -----END PGP SIGNATURE-----

[Dovecot] Wrong message information
by Anders 12 Jun '08

12 Jun '08

We have a few users that every so often get empty data in their message overview. From and subject are empty, and the date is 1-Jan-1970. When opening the message in full view, all things are fine. Also, the data in the actual maildir file is fine. It looks a lot like the issue described here: http://dovecot.org/list/dovecot/2008-March/029282.html The server is Linux, ext3, no NFS, and Dovecot 1.1.rc4. The few clients that have had this problem so far have been Outlook Express. What can be done to debug this? Thanks, Anders.

The correct way has to be one or the other: http://wiki.dovecot.org/LDA/Exim are mutually exclusive with http://wiki.dovecot.org/HowTo/DebianStable It appears that exim can either call dovecot's LDA or make the delivery itself.

I've tried compiling 1.1.rc9 on everything to hand and I get various compilation warnings (but the compilation finishes). I don't know whether any of them are worth tracking down?

[Dovecot] Lucene index not updated when one saves a message from one folder to the other
by Asheesh Laroia 11 Jun '08

11 Jun '08

I'm running 1.1 rc8, and I enabled the Lucene indexes. I find that if a bunch of messages arrive in INBOX and I then move them to archive, the next time I do an X-TEXT-FAST search, Dovecot has to re-index the mails that I think it had indexed when they were in INBOX. This seems silly, since Dovecot was the one copying them (and then deleting, since that's what I mean by move). Will this change? -- Asheesh. -- Elliptic paraboloids for sale.

[Dovecot] Auto creating client folders on the IMAP server after installing client.
by Radio Tron 11 Jun '08

11 Jun '08

Hello, could someone help. I have installed Dovecot+SSL+TLS+Thunderbird and all is well except one thing. After installing TBird and adding the required data (smtp server and auth info, imap/pop server and auth info) I am able to view mail in my TBird Inbox BUT Trash and Sent don't work - it pops up saying folder doesn't exist on the server - can't the darn thing, auto create a folder on the server instead of cribbing to me??? Is there a painless (automatic way) to auto create client directories on the Dovecot server (in the users home dir on the server - i am using maildir/). I don't want to maintain a list of clients(TBird, outlook, eudora..) with their directory structure and then remember what user has what clients installed and Gahhh! How do i do this?? Is this explained/documented somewhere in simple language(for a newbie - I'm struggling through the RFC's but they are awfully obscure and don't seem to answer my question directly)? I've also googled but that's worse. Thank you for your patience and time. I'd like to add that I plan to sync GMail, Dovecot and a multitude-of-stupid-clients in some mysterious way so any advice in advance is more than welcome.

[Dovecot] Multiple SSL certificates with dovecot.
by Andre Rodier 10 Jun '08

10 Jun '08

Hello all, By advance, I hope you'll excuse my probably not perfect English, which is not my mother tongue. I have always appreciated dovecot for this simplicity to setup and lightweight, but today, after many installations, I cannot find how to setup dovecot for my configuration. - I use only IMAPS to retrieve the mails. - I manage two domain names - I use CA-Cert certificates So,the question is : how to setup dovecot to select the appropriate certificate, according to the domain name I use when I retrieve mails using the IMAPS protocol ? Thanks. Andre Rodier.

[Dovecot] inetd & corrupt environment
by Gelu G. Lupas 09 Jun '08

09 Jun '08

Hello. I'm having the following problem with dovecot 1.0.12 and above, on a FreeBSD 7.0 system - I'm trying to run pop3-login from inetd and I keep getting this error after authentication: May 25 09:46:19 charlie dovecot: POP3(gelu): /libexec/ld-elf.so.1: environment corrupt; missing value for no-nuls oe-ns-eoh The problem persists if I uncomment the lines with no-nuls oe-ns-eoh in dovecot.conf. I've also tried running pop3-login from tcpserver/ucspi-tcp and I still get the same error. Version 1.0.1 works fine on a similar setup. Please reply if you have any idea regarding a fix for this error. I need to run dovecot under a tcp wrapper of some kind (preferably inetd) as the standalone daemon doesn't allow any method to restrict access by IP. The allow_nets extra field doesn't help much as I'm using PAM and do not want to maintain yet another passdb. Restricting access via firewall rules is not an option. Until I find a way to restrict access by IP address, dovecot will only listen on the private IP address (192.168.100.1). My dovecot configuration follows: # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: pop3 listen: 192.168.100.1 ssl_cipher_list: ALL:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login login_greeting: login_process_size: 32 login_max_processes_count: 32 login_max_connections: 128 max_mail_processes: 128 verbose_proctitle: yes first_valid_uid: 1000 mail_privileged_group: mail mail_location: mbox:~/Mail/:INBOX=/var/mail/%u mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login process_size: 64 passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ---------------------------------------------------------------------- Finally - A spam blocker that actually works. http://www.bluebottle.com/tag/4

[Dovecot] EXPUNGE delay
by Eugene 09 Jun '08

09 Jun '08

Hi people! I just switched one of my servers from Courier to Dovecot. Planned to do it anyway but had to do it faster after the discovery that courier [the version I had installed, at least] returns malformed headers for a few messages, causing Outlook Express to completely ignore them. Curiously, they were visible in Squirrelmail and Nokia Series60 e-mail client. Overal I am quite happy but have one little problem. More often than not, I have to press 'Purge' button two or more times in order to actually remove the deleted messages. The fragment of Outlook's IMAP log is below. Interestingly, Dovecot 1.0.7 (on another server) does not have such problem.

Hi I use deliver with an auth socket I have 2 namespaces (which isn't relevant here, but anyway) namespace private { separator = / prefix = location = maildir:/var/spool/mail/%1n/%2n/%n inbox = YES #hidden = yes } namespace private { separator = / prefix = mail/ location = mbox:/home/%1n/%n/mail inbox = no hidden = no } and also an general mail_location mail_location = maildir:/var/spool/mail/%1n/%2n/%n with deliver 1.0 branch everything works fine with latest deliver 1.1rc8 I get Jun 5 13:32:18 xxx deliver(<username>): mkdir(/var/spool/mail/%1n/%2n/%n/.SPAM/cur) failed: Permission denied looks like arguments don't get resolved kind regards Arne

[Dovecot] v1.1.rc9 released

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc9.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc9.tar.gz.sig Not many bug reports these last few days, so maybe this release will be a good one. + Maildir: When hardlink-copying a file, copy the W=<vsize> in the filename if it exists in the original filename. - mbox: With rc8 empty lines were inserted in the middle of saved mails' headers. - maildir: Fixed problems with opening newly saved messages which we saw in index file but couldn't see in dovecot-uidlist. Happened only when messages weren't saved via Dovecot (deliver or IMAP). - Several bugfixes to handling sort indexes - deliver: Boolean settings that were supposed to default to "yes" were set to "no" unless explicitly defined in dovecot.conf: dotlock_use_excl, maildir_copy_with_hardlinks, mbox_dirty_syncs, mbox_lazy_writes.

[Dovecot] question: auth_bind and userdb
by Matthias Šubik 07 Jun '08

07 Jun '08

Hi, this is my first post to the list, I'm not a member, please cc me directly. I'm converting from courier imap, and want to bring a special problem to your attention: I would like to use auth_bind and prefetch, b/c due to data security restriction the user information is only visible to the user himself. From http://wiki.dovecot.org/AuthDatabase/LDAP I found out that pass_attrs only works if no userdn template is set. But when unsetting userdn, dovecot-auth still tries to find the information from pass_attrs before binding. I'm no coding expert so here is my question: would it be possible to make pass_attrs work with userdn? If yes, even prefetch would work. right now, when using userdn, pass_attrs is ignored, but also userdb and user_attrs is impossible for me, because it is done anonymously, it can't reuse the bind from passdb, and can't construct a bind as passdb could. for now I defined a dummy user in ldap, but that's not the ideal solution, since then this dummy user has access to all usernames, uids, uidNumbers and gidNumbers. thank you for your attention best regards matthias subik ps: is there a list of all keywords and parameters?

[Dovecot] quotactl bug?

more on the strange quota error....this is in BSD, with quotas referenced on an NFS, and users provided by YP/NIS quotactl(Q_GETQUOTA, /.amd_mnt/crock/vol/v_user1/jdoe) failed: Operation not supported this looks strange to me, as the specification for quotactl states the function Q_GETQUOTA: Q_GETQUOTA Get disk quota limits and current usage for the user or group (as determined by the command type) with identifier id. The addr argument is a pointer to a struct dqblk structure (defined in <ufs/ufs/quota.h>). this directory path is not a valid UID...rather, its my user home directory path!

[Dovecot] v1.1.rc8 released

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz.sig I then decided to add the deliver -c feature to this release. Seems to work in my tests, but who knows if it breaks something.. Although most of the code is called only if -c parameter is given. Anyway we really should have a comprehensive test suite written some day (yes, help is really wanted for this :). So let's hope this is the last RC release. If there aren't any major problems I'll release v1.1.0 in a couple of weeks. I'll also try to merge all my different development trees into a single v1.2 code tree within a few weeks. v1.2.0 will probably be released this summer as well, since it mainly has new features that don't change existing code all that much (CONDSTORE is a bit invasive though). + deliver: Added -c parameter to provide path to delivered mail. This allows maildir to save identical mails to multiple recipients using hard links. - rc6/rc7 broke POP3 with non-Maildir formats - mbox: Saving a message without a body or the end-of-headers line could have caused an assert-crash later. - Several dbox fixes

[Dovecot] Get the size of a maildir
by Nicolas Letellier 05 Jun '08

05 Jun '08

Hello. I would like to know it a 'proper' solution exist to get the size (in MB) of a maildir. Actually, to get it, I do a 'du -sh' but I'm not sure it is a good solution. And it does not return the same value than imap-quota. Is there a command, a tool, in Dovecot to get it? There is the maildirsize but it's very difficult to get the value with a script shell and with this file. Thanks for your help. Best regards, -- - Nicolas.

[Dovecot] FreeBSD port for 1.1, some bits more...
by Geoffroy DESVERNAY 04 Jun '08

04 Jun '08

I did (re-)compile dovecot (1.1rc8) today, with managesieve (0.10.2) and sieve-plugin (1.1.5). I did modify the existing dovecot-devel port, adding managesieve patch as an OPTION, and I added a 'dovecot-managesieve-devel' port, and a 'dovecot-sieve-devel' one to be complete... Not sure everything is very complete, but at least it works for me=E2=84=A2= , and if it can help anybody to save some time... The tree ports are there: http://dgeo.perso.ec-marseille.fr/dovecot Not sure I used the very good way of building FreeBSD ports...

[Dovecot] Re maintenance of the dovecot-uidlist files
by Dann Daggett 04 Jun '08

04 Jun '08

Greetings all, I am new to dovecot, using ver 1.0.13 and IMAP with ~/Maildir delivery. I have noticed that the entries in the dovecot-uidlist files don't seem to get updated when an email is deleted or moved to .Trash. It appears that this list list would just keep growing over time, being full of no longer used filenames, and must tend to increase its processing overhead. I have also noticed that if I manually delete that file and the 3 other dovecot* files, that it gets rebuilt with only what's present. Is there provision in the dovecot code to automatically clean this up periodically? If so, are there any configuration params for it? If not, what is the preferred method for maintenance in this regard? Thank you, Dan

[Dovecot] Error using antispam plugin
by Juan Asensio Sánchez 03 Jun '08

03 Jun '08

Hi When activating antispam plugin in imap protocol, when sending an email, Evolution/Thunderbirdkeeps infinitely "Sending authentication information", and Dovecor logs shows "dovecot: May 28 10:14:35 Error: child 6910 (imap) killed with signal 11"; lots of empty folders in /tmp are created with names like "antispam-mail-ZvyWeZ". I am using Dovecot1.1 rc15 compiled from Debian source repositories (http://xi.rename-it.nl/debian/) and last version of antispam plugin, obtained with git. Any idea or help to debug? Thanks.

03 Jun '08

http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz.sig Since v1.1.0 release is getting near, this could well be the last v1.0 release. I'll still fix important bugs, but if the bugfix is large or affects only few people it'll probably get fixed only in v1.1 releases. * mbox: Enable mail_privileged_group while creating INBOX. - IMAP: Fixed a rare crash in FETCH BODY/BODYSTRUCTURE - IMAP: If mailbox is selected with EXAMINE, ignore flag changes - proxy: Login success reply was sent in two IP packets, which confused some IMAP/POP3 clients - ACL plugin leaked memory a bit - dovecot-auth: allow_nets setting with network masks didn't work correctly with big endian machines.

[Dovecot] How to set MDNSent flag on a large amount of mails?
by Patrick Nagel 03 Jun '08

03 Jun '08

Hi, after having moved a big mail archive to IMAP, I've now got the following problem: The MUA asks to send an MDN on all those old messages that contain the 'Disposition-Notification-To' header when opened. I'd like to set the $MDNSent flag on those (>10000 in a deeply nested directory structure) mails. After having read http://wiki.dovecot.org/MailboxFormat/Maildir I wrote a script that changed the filename of mails in all directories that contained the header, so that the filename contained a 'b' in the last part of the filename (after the comma), because I found '1 $MDNSent' in Maildir/dovecot-keywords. I then discovered that there can be a 'dovecot-keywords' file in each directory, and all of those files can have different flags in different order. Do I really need to write a script that evaluates each dovecot-keywords file, figures out which letter corresponds to the flag and rename the files (per directory) accordingly? Isn't there a more simple way?

[Dovecot] spamassassin, postfix with dovecot lda?
by George Mamalakis 03 Jun '08

03 Jun '08

Hi all, I am trying to setup a mail server using postfix (virtual_mailboxes), spamassassin and dovecot, along with SQL where appropriate. From my research so far I realized that, for several reasons, it is required for me to use dovecot LDA instead of maildrop, local, procmail or other alternatives. My configuration was working flawlessly, until spamassassin per-user configuration came to play. If I just wanted an MTA anti-spam gateway, I could directly call spamassassin via master.cf, or through some helper "content-filter-application" (like amavis or amavisd-new), and everything would work just fine (I tried and tested many such configurations with success). But when antispam per user preferences became my concern (Bayesian filters and classifier), I realized that spamd should be called by the LDA. With procmail this was a trivial issue, with dovecot-lda I was unable to find any solution on the web or other documentation. So my question is as follows: Is there a way to call spamc from dovecot-LDA (and/or dovecot-sieve), or is there an alternate way to do this for a site with virtual mailboxes configured with dovecot-lda? Thank you all in advance, regards, -- George Mamalakis IT Officer, Department of Electrical and Computer Engineering, Aristotle Univ. of Thessaloniki, Greece

[Dovecot] v1.1.rc6 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz.sig This is it. The first v1.1 release that actually deserves the "release candidate" name. It contains everything I require from v1.1.0 release. There are two bugs left that I'd like to get fixed, but they won't block v1.1.0 release: * index_mailbox_set_recent_uid() assert (reported by Diego Liziero) * Maildir not always finding new messages and returning them as empty (reported by Anders). The major change in v1.1.rc6 release is the SORT indexing half-rewrite. I hadn't much stress tested that code before, and once I started I just kept finding more and more weird bugs and it became extremely difficult to figure out how to fix them, so I finally decided to just redesign how it's supposed to work and then implemented that. The resulting sort code is a lot cleaner and it should also perform better (although it could still be improved a bit: the basic binary searching could be replaced with one that first binary searches between already-looked-up sort-strings and only after that binary searches the resulting space which requires slower sort-string lookups). Hopefully there are also no stupid bugs left like returning messages in wrong sort order. :) I've been wasting time this past week getting new stuff for my new apartment, but that's nearly done now. I think (hope) I'm going to be more productive in here, there are less neighbours behind walls/floors (just 1), so less potential for annoying noises. :) Thinking also seems to work better when there's more space to walk around. And finally, the changes since v1.1.rc5: * Index file format changed a bit. If an older Dovecot v1.1 reads index files updated by rc6+, they may give "Invalid header record size" or "ext reset: invalid record size" warnings. v1.0 won't give these errors. * IMAP: LIST .. RETURN (X-STATUS) command return now LIST entries before STATUS entries. * zlib plugin: Uncompress if the message begins with zlib header instead of looking at the 'Z' flag. This fixes copying with hard links. Based on a patch by Richard Platel. + IMAP: SORT index handling code was half-rewritten to fix several bugs when multiple sessions were sorting at the same time. The new code is hopefully also faster. + Maildir: If POP3 UIDL extra field is found from dovecot-uidlist, it's used instead of the default UIDL format (or X-UIDL: header). This allows easily preserving UIDLs when migrating from other POP3 servers. Patch by Nicholas Von Hollen @ Mailtrust. + Maildir: ,W=<vsize> is now always added to maildir filenames + deliver: Avoid reading dovecot-uidlist's contents if possible. + Added %T modifier = Trim whitespace from end of string - IMAP: Fixed some bugs in LIST-EXTENDED implementation. - IMAP: If client tries to change the selected mailbox state while another command is still running, wait until the command is finished. This fixes some crashes and other unwanted behavior. - allow_nets userdb setting was broken with big endian CPUs

[Dovecot] overview of patches used in Fedora
by Dan Horák 03 Jun '08

03 Jun '08

Hi, I have gone through the patches that are used in the Fedora package and probably only the "mkcert-permissions" [1] can be considered to be included upstream. It is dated into package version 1.0-0.beta2.3, but I cannot find any particular reason for the inclusion (like a bug in bugzilla, etc.). Some (winbind support, quota warnings) were obsoleted by dovecot 1.1, two are used for distro specific settings. So the only real patch that remains is the "pam_setcred" [2] patch that fixes https://bugzilla.redhat.com/show_bug.cgi?id=146198 Current state of the package for Fedora is at http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/ Dan [1] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.beta2-m… [2] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.rc2-pam… -- Fedora and Red Hat package maintainer

[Dovecot] Unsuccessful POP sessions on dovecot-1.0.3-13_60
by Patrick Ben Koetter 02 Jun '08

02 Jun '08

A Client runs a RAS network. Users access mailboxes using Outlook Express. The server runs dovecot-1.0.3-13_60. Almost a week ago users began to report that they can't retrieve their mail. The session starts, they seem to retrieve messages, but then the client reports a problem and the session is terminated. Here's what I have in the log: May 28 08:56:46 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 08:59:00 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 08:59:29 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:03:49 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:04:24 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:12:11 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:14:32 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:17:10 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:17:52 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:20:27 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:23:23 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:30:05 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 What I see is that the client seems to try to retrieve the same mails (retr=5/448621) over and over again. If they login using IMAP they don't experience any problems. Any idea what this could be? Rumor has it it's a know problem with Outlook Express and its POP implementation.

[Dovecot] Purging Deleted Messages
by Carlos Williams 02 Jun '08

02 Jun '08

I noticed today I checked a users mailbox with the mutt command: mutt -f /home/bob/email/ There I saw he had 100 messages that had been deleted but not yet purged from his inbox so they're still using up disk storage on my email server. My question is does Dovecot have a process to automatically delete these messages after a certain period of time? I would like to think that they don't just sit in a users mailbox for years waiting to be purged, right? Does anyone know exactly how this works? I checked my own mailbox using mutt and I see 11 messages that are deleted from my Thunderbird client but are still on the server (marked for deletion). How long do these messages stay there? -- Man your battle stations...

Hi We're in the phase of converting our existing unix-based users to virtual users. Goal is to make mail-spool totaly independent of home-spool. For that reason, NO files can be written to home. I've solved the problem for all files, except for .dovecot.lda-dupes. I can see in duplicate.c #define DUPLICATE_PATH "~/.dovecot.lda-dupes" I thought being clever and override in the userdb passwd following args = home=/var/spool/mail/%1n/%2n/%n but deliver totaly ignores that. does anybody has tips? kind regards Arne

[Dovecot] deliver saving mails with hard linking
by Timo Sirainen 02 Jun '08

02 Jun '08

http://dovecot.org/tmp/deliver-multiple.diff for Dovecot v1.1 implements -p <path> parameter for deliver, which reads the input mail from the specified path instead of stdin. With maildir and hardlink copying enabled, it also tries to hard link the file to destination instead of copying it. So to get the same mail delivered to multiple recipients using hard links, you'd have to write a small wrapper script that stored the mail temporarily somewhere and then called deliver for each recipient using the -p parameter. Any thoughts on if this should go to v1.1 like this? Some problems: - If you're not using a single UID/GID you probably have to make the file world-readable. - A wrapper script is kind of ugly, so it would be nice if deliver took a list of all recipients as input. But the deliver code is currently ugly enough that this would require larger changes. - Am I forgetting something?..

Why did I fail to mention that I was trying to use uiddb from Courier? :P Using your conversion script fixed it, but simply copying the Courier file crashed Dovecot. According to http://wiki.dovecot.org/Migration/Courier this is supposed to work though, so either that page is wrong, or Dovecot has a bug. >> betty - ~vpopmail/domains/bar.com/foo # gdb /usr/lib/dovecot/imap core > .. >> (no debugging symbols found) >> Core was generated by `imap'. >> Program terminated with signal 11, Segmentation fault. >> #0 0x080a539d in imap_bodystructure_write () >> (gdb) bt full >> #0 0x080a539d in imap_bodystructure_write () >> No symbol table info available. >> #1 0x08083b5c in ??

Right. This isn't implemented yet. Also I don't think it should rely on Message-ID: header proving the uniqueness. There are two ways this can be implemented reliably: 1) If the message is sent to multiple recipients using same RCPT TO command, all the recipients could be given to deliver as parameters, and deliver would know that it's the same message and they could be hard linked. 2) Keep some kind of a hash database where hash is e.g. SHA1 sum of the entire message. All messages could be then stored in some global directory and hard linked from there to users' mailboxes. When receiving a new message using an existing hash, it could still compare byte-by-byte the files to make sure that it's not a hash collision before hard linking the file. 1) probably wouldn't be too difficult to implement and probably would solve your problem (assuming the problem is that people are mailing 100MB attachments to everyone inside a company). But I don't think I have time to do it myself..

[Dovecot] Dovecot hard link problem
by 도원철 01 Jun '08

01 Jun '08

My company recently changed mail server from cyrus to dovecot. The problem is that dovecot does not support hard links for message files with same message ID. I turned on the ‘maildir_copy_with_hardlinks’ option in dovecot.conf, but it does not seems to have relation to this problem, am I misunderstood? Hard links are created when move or copy messages from one folder to other folder, but when deliver creates messages this option does not works. Our mail storage will be exhausted in few days. If you have some idea to solve this problem, please please help me. Or If you fix this problem, I will happily pay for it at reasonable cost. I installed dovecot 1.0.13 and postfix 2.5.1.

[Dovecot] Segfault in imap_bodystructure_write when searching

Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth. This loop means I have to kill either the server or the client. Running Dovecot 1.0.13 from/on Debian testing, rebuilt with vpopmail support and no other source changes. Vpopmail version is 5.4.25, latest stable. Client is Mulberry 4.0.8, and the crash seems to occur whenever any type of search is performed, be it subject, sender, body etc. Otherwise the server behaves fine. dovecot -n output: # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:9000 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes login_max_processes_count: 256 first_valid_uid: 89 mail_location: maildir:~/Maildir mail_debug: yes dotlock_use_excl: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_drop_priv_before_exec: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail auth default: user: vpopmail verbose: yes passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir Anonymized log excerpt: May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21748 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21752 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21753 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21759 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21774 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21775 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21776 (imap) killed with signal 11 ...

[Dovecot] fetchmail on demand
by Graeme Vetterlein 31 May '08

31 May '08

I hoping this is an RTFM ... and somebody can point me at the correct 'FM' :-) I've just spent a while setting my new Debian , allways-on box in what I suspect is a generally useful configuration. I have fetchmail(1) collect mail from many mailboxes via pop3. I store these mails in different mboxs according to rules in procmail(1) I then offer these out to the household via imap in dovecot(1) . I have fetchmail(1) set to poll the ISPs every 5 minutes, this seems to work fine, but there are two issues: 1: The constant polling keeps the disk spinning for no good reason (most of the time) 2: If I check my mail via a mail reader using imap to the local mboxes ...there could be mail sitting on the ISP servers I don't see (for 5 mins) Now what would be much nicer, would simply be to have dovecot(1) issue the fetchmail(1) command whenever it it got an imap request. I general what I guess I would like is: "When a request comes in (via imap) fork off a command who's name is given in the conf file. ... imap_pre_cmd="xxx" -- Graeme

[Dovecot] Web-based shared calendar synchronizable with Outlook
by Samuel HAMEAU 30 May '08

30 May '08

Hi, I know this request is a a little off-topic but may be interesting for dovecot users (at least i hope!) Does anybody has already had an experience with a calendar sharing solution including a webcalendar and an outlook connector, "compatible" with dovecot ? Today, there are many projects aiming to be a "M$ Exchange Killer" (such as Zimbra, OBM, open-exchange, etc) but they offers a global package with MTA and imap server included. I saw the page about BynariConnector (http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do not provide a webmail :( I'm afraid What I am looking for is a shared agenda solution providing a webcalendar, an outlook connector and eventually a pda connector, using (or not) dovecot, and a corporate ldap server... What are you guys using ? sam

[Dovecot] no bookeeping using public folders
by Claude Frantz 30 May '08

30 May '08

Using dovecot 1.0.10. In the config: namespace public { separator = / hidden = no prefix = Flock/ location = maildir:/home/baratin/PublicMaildir:CONTROL=~/Maildir/control/Flock:INDEX=/var/dovecot/index/%u/Flock } This should be a public mail folder owned by "baratin", "read only" for all other users. Every user has his/her own control and index area related to this public folder. I have verified, they are owner and "group" of the respective control and index area. The problem, while using Thunderbird: The "read only" user can delete messages or mark then read. But after a new session, all the messages are still "new". Of course, only "baratin" is the owner. The problem, while using mutt and IMAP: mutt refuse to change any flag because the folder is "read only". Of course, this is correct. My question: Why is no bookkeeping maintained for "other" users, although every one has his/her own control and index structure ? Thanks a lot ! Claude

[Dovecot] Problem deleting folders with Thunderbird?

I am running Thunderbird 2.0.0.14 on Windows XP. When I try to delete one of the folders I get a dialog with the following "The current command did not succeed. The mail server responded: Target mailbox doesn't allow inferior mailboxes." I am running dovecot version 1.0.13-6.fc8 under Fedora 8. The output of dovecot -n is below; [root@www knute]# dovecot -n # 1.0.13: /etc/dovecot.conf protocols: imaps pop3s disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Is there something to be configured to allow mail box deletion?

[Dovecot] dovecot's deliver and SELinux
by Dan Horák 29 May '08

29 May '08

Hello, I am the new maintainer of dovecot for Fedora and Red Hat and so I am trying to cleanup some old reported bugs. One of them is a problem when "deliver" writes of temporary files into /tmp are blocked by SELinux policy (https://bugzilla.redhat.com/show_bug.cgi?id=424091) From the SELinux's point of view it is bad when system services try to write into /tmp (for detail see http://danwalsh.livejournal.com/11467.html) The solution looks simple - just to switch from /tmp to PKG_RUNDIR (line 472 in deliver.c for dovecot 1.0) for writing the temp files. But this raises two questions - will it really work and when yes, is it acceptable for the author? Thanks, Dan -- Fedora and Red Hat package maintainer

[Dovecot] Trim trailing whitespace from username
by David Jonas 29 May '08

29 May '08

Recently we changed Postfix to use Dovecot for our SASL authentication and we ran into trouble with some of our clients having extraneous spaces at the end of their usernames. The quick fix was to add a space to username_chars. The slightly longer fix was a pretty simple patch to Dovecot. I put the trimming in auth_request_fix_username. I didn't think it warranted a full strfuncs function. If there is a better way to do this I'm all ears. I don't really like patching with my own code, even if I did essentially steal if from the kernel's strstrip(). diff -u dovecot-1.1.rc5/src/auth/auth-request.c dovecot-1.1.rc5-patched/src/auth/auth-request.c --- dovecot-1.1.rc5/src/auth/auth-request.c 2008-05-04 15:01:52.000000000 -0700 +++ dovecot-1.1.rc5-patched/src/auth/auth-request.c 2008-05-16 00:44:15.000000000 -0700 @@ -22,6 +22,7 @@ #include <stdlib.h> #include <sys/stat.h> +#include <ctype.h> struct auth_request * auth_request_new(struct auth *auth, const struct mech_module *mech, @@ -750,6 +751,7 @@ { unsigned char *p; char *user; + size_t size; if (strchr(username, '@') == NULL && request->auth->default_realm != NULL) { @@ -759,6 +761,16 @@ user = p_strdup(request->pool, username); } + /* Trim trailing whitespace from the username */ + size = strlen((unsigned char*)user); + if(size) { + p = user + size - 1; + while (p != user && isspace(*p)) + p--; + *(p + 1) = '\0'; + p = NULL; + } + for (p = (unsigned char *)user; *p != '\0'; p++) { if (request->auth->username_translation[*p & 0xff] != 0) *p = request->auth->username_translation[*p & 0xff];

[Dovecot] Sieve/Vacation
by Ulrich Schreiner 29 May '08

29 May '08

hi, i'm using 1.1.rc5 but the same error occured with 1.0.13. the dovecot package was installed on centos 5 with rpm's from atrpms. exim 4.69. everything works fine except the vacation's from sieve. don't get me wrong, sieve works for everything, including mailforwards, or sorting in subfolders. but when i have a vacation, the script is compiled, but it produces the following output: sieve_execute_bytecode(/var/virtuser/test@<adomain>.sievec) failed (the "<adomain>" is replaced with the real domain of the user). i use virtual users in different domains. the sieve-scripts are generated by horde/ingo and stored via ftp in the "/var/virtuser" directory with the pattern "%u.sieve". the "sievec" files are up-to-date, because: a) i can delete the "sievec" files and they are regenerated b) i can "sieved" them and get an disassembled output with the vacation rule inside but when executing the script (when a mail arrives) the upper error is logged and no vacation is processed. the same error occured with 1.0.13 thank you </usc>

[Dovecot] Dovecot 1.0 rc15 + Quota by user using mysql
by Lucas Carlessi 28 May '08

28 May '08

Hi all, I installed the Dovecot on a Debian by apt-get, it's all working except quota by user.. I have a database with all quotas in bytes, and that lines in /etc/dovecot/dovecot-sql.conf : driver = mysql connect = host=127.0.0.1 dbname=mailserver user=USER password=PASS default_pass_scheme = CRYPT password_query = SELECT email as user, password FROM view_users WHERE email='%u'; #Quota: user_query = SELECT home AS maildir, 5000 AS uid, 5000 AS gid, CONCAT('dirsize:storage=', ROUND( view_users.quota / 1024) ) AS quota FROM view_users WHERE email='%u'; and in /etc/dovecot/dovecot.conf : protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } plugin { #quota = maildir:ignore=Trash } But when I open the webmail I have no limit quotas! If I put quota = maildir:storage=101480 in plugin the quota works fine at 100MB, but in all users... Is the query right? There is another way to configure quotas by user in Dovecot 1.0 using mysql? Sorry my bad English, and thank you all!

[Dovecot] Vanishing maildirsize files with 1.0.7 using 'deliver' via postfix
by Jason Forester 28 May '08

28 May '08

Aloha, I've searched the list and have found no similar reports, so I'm asking here. We have 3 RH5.1 boxes running the stock Postfix 2.3.3, but due to issues with the stock Dovecot 1.0rc15, Redhat supplied us with the version of Dovecot 1.0.7 that will be in Redhat 5.2. The mail store is automounted per-user from a Sun box via NFS. We were using it with no problems until last Friday, when we attempted to implement quotas. I had done quite a lot of testing on a single system, so I didn't anticipate any issues here. I created maildirsize files for each user in the NFS-mounted /var/spool/mail/$USER and everything seemed fine. I changed mailbox_command to /usr/libexec/dovecot/deliver in postfix main.cf. Mail was delivered, quota files updated, all good. However almost immediately a maildirsize folder vanished. Soon after another, then another, and now we're missing nearly 40 of them. Any ideas as to why they're vanishing? Something to do with NFS? I've tried to trigger it by massively sending to the same user on all three systems but have yet to reproduce it at will. Any clues would be appreciated. For reasons of support I cannot upgrade to a later dovecot at this time. Best Regards, - jason

[Dovecot] Dovecot quota for mailadministrator
by Markus Hofer 27 May '08

27 May '08

Hallo, i have a question for the quota with dovecot. I plan to go from our cyrus installation to dovecot. I have just install dovecot without problem with mysqldb and quota per user. Quota work well and the user receive always via Webmail or client the quota information. My question is: With cyrus the mailadministrator has the possibility to see the quota for all users with the command "quota". Output or example: 300000 9 28305 user.tinfo With that way the administrator could have always a look if some users have quota problems. My question is, if dovecot has some similar command for the administrator? Thanks in advance. Markus

[Dovecot] Problem with checkpassword-reply
by sawyer x 27 May '08

27 May '08

Hello I posted an earlier post on problems with getting usernames. That one is solved, thank you. I'm currently having trouble executing checkpassword-reply. The maillog shows the following error: (substituting rip/lip/user/domain) May 27 07:21:06 saw dovecot: Logins with UID 0 not permitted (user user(a)domain.com> May 27 07:21:06 saw dovecot: imap-login: Internal login failure: user=<user(a)domain.com>, method=plain, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS My script reads fd3 right and gets all the details correct. Then runs the following code: --- $REPLY = $ARGV[0] || exit 111; # this is actually run much earlier $ENV{HOME} = "$USERSHOME/$domain/$user"; $ENV{USER} = $user; # effective gid $) = 300; # effective uid $> = 300; exec $REPLY; --- I've looked at the checkpassword-reply code (thank god for open source software) and I saw that it opens fd4 for writing. I couldn't find any documentation about this and couldn't find anyone who is using checkpassword-reply. No sample scripts, no examples, and the documentation on the site is extremely scarce. The wiki docs indicate I should just execute it - which I do - but that does not help. Also, the debugging isn't very meaningful. I'm definitely changing the UID and GID, but it's not apparent in the maillog. The fie permissions on checkpassword-reply show I could execute it under any user and I've tried that with "sudo -u <user> /path/to/checkpassword-reply. On a post somewhere in the vortex of the internet someone said Dovecot does not allow any uid/gid under 99 (which is why I tried 300), but I couldn't find any documentation for that anywhere in the wiki either. What am I missing and is there anything I've missed that would have prevented me from emailing the mailing list with this long email? Thanks, Sawyer.

[Dovecot] mbox From escaping implementation ?
by Nicolas KOWALSKI 27 May '08

27 May '08

Hello, I read in the wiki (http://wiki.dovecot.org/MailboxFormat/mbox) about "From Escaping": "Dovecot doesn't currently do this escaping however. Instead it prevents this confusion by adding Content-Length headers so it knows later where the next message begins. Dovecot doesn't either remove the '>' characters before sending the data to clients. Both of these will probably be implemented later." As I understand it, this makes the mbox format of dovecot slightly incompatible with other mbox-capable clients, because if they read the data files directly, they may understand a line starting with an unescaped 'From ' as the start of a new message. Right ? Are there any plans to implement this escaping in the future (1.1.x or 2.0.x?) Thanks, -- Nicolas

[Dovecot] Sieve plugin changes 'To' header on redirect
by Patrick Nagel 27 May '08

27 May '08

Hi, I'm a bit confused by the fact that the 'To' header is being modified by sieve when a message is being redirected. RFC3028 states in chapter 4.3: > The "redirect" action is used to send the message to another user at > a supplied address, as a mail forwarding feature does. The > "redirect" action makes no changes to the message body or existing > headers, but it may add new headers. The "redirect" modifies the > envelope recipient. (see http://www.ietf.org/rfc/rfc3028.txt) The situation here is as follows: I'm sending a mail to "city(a)company.net" (To: ...), which is being delivered to "city(a)city.company.net" (Delivered-To: ...). User city has the following sieve script: redirect "other(a)company.net"; keep; One would expect, that the 'To:' header is identical in both mails, but instead I get something like this: Mail in 'city' mailbox: > Delivered-To: city(a)city.company.net > To: city(a)company.net > Subject: test mail (Redirected) Mail in 'other' mailbox: > Delivered-To: other(a)city.company.net > To: city(a)city.company.net > Subject: test mail It seems as if sieve uses the 'Delivered-To' header as the 'To' header in the redirected mail - which is not what I need. Am I misunderstanding something here, or does dovecot's sieve plugin not act according to the RFC?

[Dovecot] Bug: subscriptions file does not take on the same perms as dovecot-shared
by Damon Atkins 27 May '08

27 May '08

All, Version: 1.1.rc5 Solaris x86 on ZFS Shared Folder Bug, renamed a folder with sub folders (Maildir format) After the rename the subscriptions file is own by the person who renamed the folders, and access is owner rw only. Instead it should be the same as dovecot-shared which would general be rw owner, and rw group for a shared folder. Cheers Damon.

[Dovecot] Multiple files for sieve
by Adrián Ribao Martínez 27 May '08

27 May '08

Hello, I have this line in the plugins configuration section : sieve = /etc/dovecot/sieve Where: /etc/dovecot/sieve: require "fileinto" if header :contains "Subject" "****SPAM****"{ fileinto "spam"; } I want this filter for all the users of the system, but I also want to tell dovecot to look in the /home/user/mail/.sieve file for custom per-user filters. Can I do this? Thank you. -- Adrián Ribao Martínez

[Dovecot] Dovecot crash in 1.0.9
by Peter Eriksson 26 May '08

26 May '08

I've been having a problem with a crashing Dovecot the last couple of months where it crashes after a couple of weeks of uptime. Been a bit difficult to diagnose. Anyway, we're now running 1.0.9 on a Sun Fire T1000 running Solaris 10. Any good ideas on how to pin-point the problem? - Peter Here's the output from syslog when the last crash happened: May 14 11:46:50 ifm.liu.se dovecot: [ID 107833 mail.info] imap-login: Login: user=<hidta>, method=PLAIN, rip=130.236.160.20, lip=13 0.236.160.6, secured May 14 11:46:50 ifm.liu.se dovecot: [ID 107833 mail.info] auth(default): new auth connection: pid=4054 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(joher): file maildir-uidlist.c: line 143: assertion failed: (UIDLIS T_IS_LOCKED(uidlist)) May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(joher): Raw backtrace: 0x100082768 -> 0x1000298ec -> 0x100027e70 -> 0x100028fa8 -> 0x1000294a8 -> 0x10002057c -> 0x100014824 -> 0x100016cb4 -> 0x1000170d4 -> 0x10008a458 -> 0x100089938 -> 0x100022ad 8 -> 0x10000fe7c May 14 11:46:51 ifm.liu.se dovecot: [ID 684838 mail.error] child 3677 (imap) killed with signal 6 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.warning] IMAP(hidta): Killed with signal 15 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.warning] IMAP(peber): Killed with signal 15 ...

[Dovecot] Sort output of dovecot -n alphabetically?
by Charles Marcus 25 May '08

25 May '08

Is there a way? Postfix does this by default, and it makes it much less likely to miss/overlook a setting... If there is no way, any chance to modify it so that it does? Thanks for dovecot! Really looking forward to 1.1 release! -- Best regards, Charles

[Dovecot] dovecot developer documentation
by Piotr Wadas 25 May '08

25 May '08

Hello, I want to create some specific plugin for dovecot v1.1 (rc5). Where can I find some developer documentation ? Can I build my plugin separately, or do I need to rebuild dovecot again ? I'm looking into code, and analyzing some simple plugins, but hooks documentation or any hints you could give would be very helpful.. AFAIK there's no search for mailing list archives available, to let me search for some older guidance in this case :( Regards, Piotr

[Dovecot] Error while set mailQuota=0 with mbox and LDAP backend

Hi, all. I have OpenLDAP(+qmail.schema), Dovecot, Postfix installed on RHEL 5.1 (x86_64), and they works fine with mbox format. The problem is if i set 'mailQuota=0' in LDAP, postfix can't send mail to recipient user. But it works fine with 'mailQuota != 0', such as '10240'(10M). What's wrong with my mail server setting? How can i solved this issue? Thanks very much.

[Dovecot] Auto-subscribe to folders
by Juan Asensio Sánchez 25 May '08

25 May '08

Hi I will use autocreate plugin in a new installation, and client has asked me if the users can be auto-subscribed to certain folders. Example: the users will have an autocreated Junk folder (for SPAM) and we want the users not to be un-subscribed for this folder; so if the user wants to be unsubscribed (from outlook, webmail, etc), there are two options: a) the action is rejected or denied; b) the next time he/she logins, then the folder is autosubscribed again. Could this be done? How? Thanks in advance.

[Dovecot] Domain variable in checkpassword
by sawyer x 25 May '08

25 May '08

Hello everyone I'm using the checkpassword method but I don't get the domain a user inputs. I can't cross check per virtual domains if I'm not getting one, which means it renders all my efforts useless. I've tried sending %d as a variable to my checkpassword script, but I'm just getting %d instead. This is a dump of my information: %ENV = { 'USERNAME_TRANSLATION' => '', 'SYSLOG_FACILITY' => '16', 'CACHE_SIZE' => '0', 'RESTRICT_GID_LAST' => '', 'TCPREMOTEIP' => '213.31.43.3', 'RESTRICT_GID_FIRST' => '', 'AUTH_NAME' => 'default', 'CACHE_TTL' => '3600', 'SERVICE' => 'IMAP', 'USERDB_1_DRIVER' => 'prefetch', 'USERNAME_CHARS' => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@', 'DOVECOT_MASTER' => '1', 'RESTRICT_SETGID' => '', 'AUTH_WORKER_MAX_COUNT' => '30', 'AUTH_WORKER_PATH' => '/var/run/dovecot/auth-worker.25291', 'PASSDB_2_ARGS' => '/etc/exim/checkp %d', 'USERNAME_FORMAT' => '', 'LOCAL_IP' => '128.177.27.100', 'PASSDB_2_DRIVER' => 'checkpassword', 'PASSDB_1_DRIVER' => 'pam', 'REALMS' => '', 'PROTO' => 'TCP', 'ANONYMOUS_USERNAME' => 'anonymous', 'RESTRICT_SETEXTRAGROUPS' => '', 'TCPLOCALIP' => '128.177.27.100', 'LOG_TO_MASTER' => '1', 'MASTER_USER_SEPARATOR' => '', 'RESTRICT_SETUID' => '', 'REMOTE_IP' => '213.31.43.3', 'RESTRICT_USER' => '', 'DOVECOT_VERSION' => '1.0.rc15', 'MECHANISMS' => 'plain', 'RESTRICT_CHROOT' => '', 'DEFAULT_REALM' => '' }; ARGS: @ARGV = [ '%d', '/usr/libexec/dovecot/checkpassword-reply' ]; Thanks, Sawyer.

First, thanks for this great product. We migrated from Courier last week with only small bumps along the way. We have a few hundred active users with a mix of pop3 and imap clients. The server is running on sparc Solaris 9. We're seeing a problem now with the number of "imap-login" processes rising slowly to it's limit and then (understandably) not letting any more logins happen. Legitimate users seem to have no problem logging in until the limit is hit. Another odd thing is that this is not a problem for pop3-login processes, just imap... I've tried changing some obvious things including the passdb from pam to passwd and back again, but here's the current dovecot -n output: # 1.0.13: /opt/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_cert_file: /opt/dovecot/etc/ssl/certs/dovecot.pem ssl_key_file: /opt/dovecot/etc/ssl/certs/key.pem disable_plaintext_auth: no login_dir: /opt/dovecot/var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/Maildir mmap_disable: yes mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private prefix: INBOX. inbox: yes auth default: verbose: yes passdb: driver: pam userdb: driver: passwd Any ideas or advice?

[Dovecot] Bug [1.1rc5]: Crash during "CPU architecture changed" index upgrade

[Dovecot] Maildir locking by LDA of dovecot
by Mike Grozak 25 May '08

25 May '08

Hi all! First of all, I want ti thank the whole Dovecot community (developers for developing and fast responses, users for populating and responses too). Dovecot is a really good and fast IMAP server - it serves near 3000 in our installation. Now I have a problem and request community's help its resolving;) Dovecot version: 1.0.13, compiled with vpopmail support. I have an account spam(a)domain.com (:-), in which we put all our spam (we gather statistic later). There can be 10 and more delivery attempts in a second to maildir of this account during the spam attacks on our server. The queue of our server can grow up to 20k messages, and all of these messages are sent to spam(a)domain.com. I found a lot of such strings in dovecot.log file during such DoS attack: dovecot.log:deliver(spam@domain.com): May 16 04:18:48 Info: msgid=<01c8b6da$a8bacf80$b7af2abe@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:18:59 Info: msgid=<6611811842.20080516012444(a)poiusadfhnvxzmdiasdasgkhlsdkfg.com>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:06 Info: msgid=<01c8b6a8$7b552e00$a0a4034c@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:14 Info: msgid=<360825920.32055246029506(a)mirgames.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:50 Info: msgid=<01c8b6b1$0df9cb00$cc36dfc9@tek2>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:00 Info: msgid=<087901c7ca2d$ef272640$1e01a8c0(a)telefonia.InterCable.net>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:01 Info: msgid=<000701c8b6d2$01ff999f$c491aca7@snoueiij>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:32 Info: msgid=<000801c8b69b$060c0230$3cd8a4b7@cpbvlrx>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<000801c8b6a5$04ba6412$9910848d@aldldr>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<031401c772e2$adc5be40$1e01a8c0(a)mtu-net.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:23:08 Info: msgid=<01c8b6db$0222fe80$b7af2abe@info>: save failed to INBOX: Timeout while waiting for lock What can I do for resolving this locks?

[Dovecot] Multiple private namespace question
by Troy Engel 24 May '08

24 May '08

(apologies if this has been covered, can't find it on the Wiki/FAQ, etc.) We have a stellar, fantastic, hard working Dovecot 1.0.5 (yes, I need to upgrade) installation running in Courier-IMAP compatibility mode: mail_location = maildir:~/Maildir:INDEX=/var/spool/dovecot/indexes/%1u/%u namespace private { separator = . prefix = INBOX. inbox = yes } A user purchased a Windows Mobile 6 device which is ignoring the namespace (it's the device's bug for sure, other people report it on forums around the 'net) and there's no way on this device to manually set the Prefix; so, his Sent mails are never making it back to the server when replying from the device because of the missing INBOX. issue. Can I add a second hidden namespace with no prefix: namespace private { separator = . prefix = hidden = yes } ...to fix his problem, but without adversely affecting anyone else? The issue that has given me pause is this comment in the config file: "Default namespace is simply done by having a namespace with empty prefix." ..but then there's also: "If namespace is hidden, it's not advertised to clients via NAMESPACE extension or shown in LIST replies." I'm not sure what exactly will happen by adding a hidden namespace with no prefix after an advertised namespace with a prefix; this is a live server, so mucking up the works with a bad config is not an option. :) Anyone have a clue if this is valid/good/correct and Dovecot will play nicely? Many thanks, -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] I've moved
by Timo Sirainen 24 May '08

24 May '08

I've moved again. If you need to know my new address, whois imapwiki.org (dovecot.org address is still lagging behind). My living costs also increased some because of this, but hopefully I'll get enough money from Dovecot coding to pay for it. :) I'll try to get back to replying mails within the next few days.

[Dovecot] Disallow folder delete
by Kenneth Porter 24 May '08

24 May '08

Is there a straightforward way to disallow the deletion of all IMAP mailboxes? I have a user who's deleted an important IMAP mailbox and I'm now recovering a recent copy from the backup. But I'd rather just blanket disallow all folder deletions. The user is using Thunderbird and this has happened more than once so I suspect Tbird is willing to let a folder get deleted too easily. Perhaps there was a delay in the confirmation dialog and the user clicked ahead and confirmed something he shouldn't have. I'm looking at <http://wiki.dovecot.org/ACL> and it looks like I should be able to use a group override to disallow "x" (mailbox delete) but the page says that groups aren't implemented, so I don't know how one says that nobody can do this for any mailbox. I'm using 1.2.rc15 from CentOS 5 (RHEL5 equivalent).

[Dovecot] Don't Understand Error Entry
by Carlos Williams 24 May '08

24 May '08

I am using dovecot-0.99.11-8.EL4 on my system and decided to check the logs since I just took over as the administrator on this system and I noticed the same error entry over and over in the logs. I went to /var/log/dovecot.err and see: imap(rangry): May 22 13:33:31 Error: Error parsing IMAP envelope: "Thu, 20 Apr 2006 10:10:01 -0400" "Re: Hi there I have a question" (("Rodney Angry" NIL "rodney.s.angry" "example.com")) (("Rodney Angry" NIL "rodney.s.angry" " example.com")) ((NIL NIL "rodney.s.angry" "example.com")) (("Gryder, Connie" NIL "CONSTANCE.L.GRYDER" "example.com")) NIL NIL "< DD3761B99DC88F4284EDE00D608383C65DF16C(a)0088-its-exmp01.us.example.com>" NIL I don't understand what this error message means and why its flooding my logs. I do know the that the name in parenthesis on line one is a user on my email server. <rangry> is a user on my domain with a valid email account but I can't tell if the problem is coming from example.com or originating from <rangry>. Anyone happen to know what is causing this? I don't know if you guys need my config here so I don't want to flood this message. If this makes sense to anyone, please let me know what I can do to resolve this or keep this from flooding my email server. Thanks!

[Dovecot] log contents questions?
by Knute Johnson 24 May '08

24 May '08

I switched from using Pegasus and POP3 to Thunderbird and IMAP for my email. Now I get a lot of "Corrupted index cache file" errors in my log.

[Dovecot] procmail --> deliver question
by Ben Budts 23 May '08

23 May '08

Hi there, I use dovecot-1.1-rc4, got imap, imaps, pop3 & pop3s working fine with the mbox format. I use sendmail-8.14.2 as an MTA, sendmail uses procmail as an LDA. I migrated to maildir format now, and pipe all my mail to deliver right now to be able to make use of the indexing etc... Problem is I run into some errors : #My .procmailrc PATH=/usr/bin:/usr/local/bin:/usr/sbin SHELL="/bin/bash" SENDMAIL="sendmail -oi -t" DELIVER="/opt/dovecot/libexec/dovecot/deliver" LOGFILE="$HOME/procmail.log" #/dev/null VERBOSE=on LOGABSTRACT = "all" #DEFAULT="$HOME/Maildir/" #MAILDIR="$HOME/Maildir/" :0 w | $DELIVER ##### My procmail.log : procmail: [12743] Wed May 21 13:43:38 2008 procmail: Assigning "LOGABSTRACT=all" procmail: Executing "/opt/dovecot/libexec/dovecot/deliver" Fatal: destination user parameter (-d user) not given procmail: Error while writing to "/opt/dovecot/libexec/dovecot/deliver" procmail: Program failure (64) of "/opt/dovecot/libexec/dovecot/deliver" procmail: Assigning "LASTFOLDER=/opt/dovecot/libexec/dovecot/deliver" procmail: Locking "/var/spool/mail/kris.lock" procmail: Assigning "LASTFOLDER=/var/spool/mail/kris" procmail: Opening "/var/spool/mail/kris" ####" It's not working out and he falls back to delivering his mail to /var/spool/mail/%u Could you guys point me out in the right direction please ? Another question about the logging with deliver... I've put the following in my deliver.conf : deliver.conf in the lda section : log_path = /var/log/dovecot/deliver.log info_log_path = /var/log/dovecot-deliver.log root@blaat:/home/kris# ls -la /var/log/dovecot/ total 232 drwxrwxrwx 2 root root 4096 2008-05-20 10:44 . drwxr-xr-x 11 root root 4096 2008-05-19 10:08 .. -rw-rw-rw- 1 root root 0 2008-05-20 10:44 deliver.log But it's not logging at all... Also tried the syslog alternative, no logging either.

Hi,I need some help. I use dovecot and dovecot-sieve on a freebsd 7.0-release. everything worked fine without dovecot sieve. I want to deliver amavisd spam marked messages to the 'spam' folder of the user. the system uses virtual environment with multiple domains (and users).all want is a global sieve, to all users, all domains.I googled, but I cannot find the problem,my protocol lda section:protocol lda {    log_path = /usr/local/vmail/dovecot-deliver.log    sieve_global_dir = /usr/local/vmail/globalsieverc    mail_plugins = cmusieve    mail_debug = yes    log_path = /var/log/dovecot-deliver    info_log_path = /var/log/dovecot-deliver     postmaster_address = postmaster(a)tamann.hu    mail_plugin_dir = /usr/local/lib/dovecot/lda    sendmail_path = /usr/sbin/sendmail}globalsieverc:require "fileinto";if header :contains "X-Spam-Flag" "YES" {        fileinto "Spam";        stop;}thank you for your help,and sorry for my bad english.t

[Dovecot] auth_socket_path permissiones
by Adrián Ribao Martínez 22 May '08

22 May '08

Hello, I'm using dovecot 1.0 under debian etch. The lda socket path is set to: auth_socket_path = /var/spool/postfix/private/auth But this gives me the error: net_connect(/var/spool/postfix/private/auth) failed: Permission denied I suppose deliver is run as dovecot user. I read about running deliver as root with the suid bit set. I'm not quite sure if this is a good solution. Is there any other way. In the wiki says: "Most MTAs won't let you run deliver as root, so for now you'll need to make it setuid root. However deliver isn't designed to be run as setuid-root" My MTA is postfix, does someone know if postfix let me run deliver as root? If not, should I go to the setuid option? Thank you. -- Adrián Ribao Martínez

[Dovecot] Clients hang because imap-login discards post-login commands
by Mike Abbott 22 May '08

22 May '08

Some of my IMAP clients hang when connecting to Dovecot 1.1.rc5. I believe the problem is that imap-login reads eagerly rather than sparingly. If a client sends a login user password b select Inbox all at once, without waiting for the login reply before sending the select, imap-login eats the second command (reads it from the socket and does nothing with it; system call tracing confirms this) and the client hangs waiting for a reply to the select command. I can reproduce this simply using telnet to the dovecot on localhost, as long as I send both lines at once (I paste them in together). $ telnet localhost 143 * OK Dovecot ready. a login user password b select Inbox a OK Logged in. <dovecot never replies to select> This may also be true with pop3-login, I have not checked. It does happen (with IMAP) when authentication is delayed and Dovecot responds with "* OK Waiting for authentication process to respond.." but I believe that shares the same underlying cause as the simpler case above. I believe the login processes should read only as much as they need to satisfy the login request and leave subsequent commands in the socket for post-login processing. Or, the login processes should pass the remainder of their input buffers to the mail processes so no commands are dropped. This section of RFC 2060 explains why I think this: 5.5. Multiple Commands in Progress The client MAY send another command without waiting for the completion result response of a command, subject to ambiguity rules (see below) and flow control constraints on the underlying data stream. Similarly, a server MAY begin processing another command before processing the current command to completion, subject to ambiguity rules. [...] The exception is if an ambiguity would result because of a command that would affect the results of other commands. Clients MUST NOT send multiple commands without waiting if an ambiguity would result. If the server detects a possible ambiguity, it MUST execute commands to completion in the order given by the client. So it appears that both the client and Dovecot may be in violation, depending on how you define "ambiguity." The RFC does not explicitly define whether login causes an ambiguity, but I personally believe that login does "affect the results of other commands" (the login may fail, for instance). So the client should not issue commands before receiving the login reply, and Dovecot should not drop commands during login. I have reported the client issue to the developers of the IMAP client, as I am reporting the server issue to you. Fortunately for me, only one or the other needs to change to erase the symptom (hung clients), but fixing both would be best. Thanks for your attention.

[Dovecot] Dovecot or postfix Quota
by Adrián Ribao Martínez 22 May '08

22 May '08

Hello, I'm a bit confused with the dovecot quota support. What is it for? I thought postfix should be the one managing the quota. If I set up a quota in dovecot, does dovecot keep the messages size under certain limit? What happen when you reach the quota limit? What's the difference between postfix quotas and dovecot quota? I'm confused about this. Thank you! -- Adrián Ribao Martínez

[Dovecot] VMware and Time moved backwards
by Robert Henjes 22 May '08

22 May '08

Hi, I followed the discussions regarding the "time moved backward" problem and the use of ntp in such cases. At our department we are running two dovecot servers within an vmware server environment, and unfortunately the timedrift (with ntpd active) exceeds sometimes up to 30 minutes virtual drift within 10 minutes realtime (mostly into future). This is due to some overcorrections within the TSC algorithms of the vmware virtual machine. More information and some hints to workaround are documented here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=di… Nevertheless we are currently working on evaluating a stable solution by doing some system measurements, which would be the best option to cope with this problem, since the XEN environment seems to have a similar issue. Running "ntpdate -u" as a cronjob is not an option due to two facts: a) Time is moving quickly and may cause "major problems" ;) b) It is not recommended by the vmware team itself as well We are currently considering two options: a) Using the "clock=pit" kernel option, which may cause the system to be to slow b) using vmware tools and use only the ntp synchronisation of the host (we have currently only little experience with this). Also vmware tools are somewhat critical in case of updates. So our intention was to use as less vmware specific things as possible within the virtual machine, so only our host itself depends on vmware specific software. The question is, which option would you prefer? Is there another solution beside the mentioned ones? According to Timo's postings, workarounds within the dovecot itself to cope with "time moved backward" problems are not planned yet to be impelented. So best regards, Robert

Thank you for the prompt answers @Luuk Vosslamber >finding correct values for the following entrys in your vmware(host) >config file might solve some things: >host.cpukHz = 1596000 <== depends on processor speed ;-) >host.noTSC = TRUE >ptsc.noTSC = TRUE >hostinfo.noTSC = TRUE >tools.syntime = TRUE > >Above values go with the presumption that the host CPU is running at a >fixed frequency.

We tried your parameters already, but they are not an option, unless you have the following a) machine smp disabled (enabled in our case) b) other machines on the host system have really low load c) vmware tools should not be missing on guest @Peter Hessler >never ever ever run ntp on virtual hardware. > >instead, run ntp on the host hardware, and tell the client to always obey the bios clock. I add "* * * * * /sbin/hwclock --localtime -->hctosys" >to my crontab for that. Thank you very much Peter, this hint opens up a bunch of new possibilities only mentioning "adjtimex" ... BUT: And this brings me back to, why I posted this issue to the dovecot mailinglist and not elsewhere: All these guest based solutions lead to a fixed time movement (we used previously ntpdate -u every 7 minutes, ntp itself synchronizes every 11 minutes with the hardware clock for calculating drifts), which happens about once per week, that the time movement backward is larger than 11 seconds between two dovecot imap operations, which leads to an immediate shutdown of the dovecot process. All other services on these machine can cope with this. So the question is how to get these adjustments smooth or close to realtime. Best regards, Robert Btw.: We are running Dovecot 1.0.13 from Debian etch-backports (which is an important information since debian seems to have its own rules ;) )

[Dovecot] Maildir locking by LDA of dovecot
by Mike Grozak 21 May '08

21 May '08

Hi all! First of all, I want ti thank the whole Dovecot community (developers for developing and fast responses, users for populating and responses too). Dovecot is a really good and fast IMAP server - it serves near 3000 in our installation. Now I have a problem and request community's help its resolving;) Dovecot version: 1.0.13, compiled with vpopmail support. I have an account spam(a)domain.com (:-), in which we put all our spam (we gather statistic later). There can be 10 and more delivery attempts in a second to maildir of this account during the spam attacks on our server. The queue of our server can grow up to 20k messages, and all of these messages are sent to spam(a)domain.com. I found a lot of such strings in dovecot.log file during the such DoS attack: dovecot.log:deliver(spam@domain.com): May 16 04:18:48 Info: msgid=<01c8b6da$a8bacf80$b7af2abe@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:18:59 Info: msgid=<6611811842.20080516012444(a)poiusadfhnvxzmdiasdasgkhlsdkfg.com>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:06 Info: msgid=<01c8b6a8$7b552e00$a0a4034c@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:14 Info: msgid=<360825920.32055246029506(a)mirgames.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:50 Info: msgid=<01c8b6b1$0df9cb00$cc36dfc9@tek2>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:00 Info: msgid=<087901c7ca2d$ef272640$1e01a8c0(a)telefonia.InterCable.net>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:01 Info: msgid=<000701c8b6d2$01ff999f$c491aca7@snoueiij>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:32 Info: msgid=<000801c8b69b$060c0230$3cd8a4b7@cpbvlrx>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<000801c8b6a5$04ba6412$9910848d@aldldr>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<031401c772e2$adc5be40$1e01a8c0(a)mtu-net.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:23:08 Info: msgid=<01c8b6db$0222fe80$b7af2abe@info>: save failed to INBOX: Timeout while waiting for lock My dovecot.conf: $ cat /etc/dovecot.conf | grep -v \# | grep -v ^\n protocols = imap pop3 log_path = /var/log/dovecot.log ssl_disable = yes login_user = dovecot login_process_per_connection = no login_max_connections = 1024 login_greeting = Server is ready. >>dotlock_use_excl = yes - can it be the reason? fsync_disable = yes first_valid_uid = 39 last_valid_uid = 39 first_valid_gid = 39 last_valid_gid = 39 max_mail_processes = 1024 maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { mail_plugins = quota imap_quota login_greeting_capability = yes imap_client_workarounds = outlook-idle } protocol pop3 { pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)tversu.ru mail_plugins = quota cmusieve sendmail_path = /usr/lib/sendmail fsync_disable = no } auth_cache_size = 10240 auth_username_format = %Lu auth default { mechanisms = plain login cram-md5 socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } } passdb vpopmail { args = cache_key=%u dovecot } userdb vpopmail { } user = vpopmail ssl_require_client_cert = no } dict { } plugin { quota = maildir:ignore=Trash } What can I do for resolving this locks?

[Dovecot] Running sieve filters on already delivered mails

I want to know what the best way to run sieve filters on already delivered mail is. Problem is that I have a rather large unfiltered mailbox and filtering it by hand would be a PITA. I don't mind coding something up to do this, but I just don't think that I'm the first one with this problem. Thanks - Axel

[Dovecot] New ManageSieve releases: v0.10.2 for Dovecot 1.1.rc4 and v9.3 for Dovecot 1.0.13
by Stephan Bosch 20 May '08

20 May '08

Hello Dovecot users, Recently, I was pointed towards a problem in the managesieve SASL implementation. As it turns out there was a bug in handling mechanisms that expect more than a single client response. That is why the PLAIN mechanism works and the (obsolete) LOGIN mechanism fails (along with probably many others). This problem was present in both v9.2 and v0.10.1 for Dovecot 1.0 and 1.1 respectively. This issue is fixed in the new releases: Change Log v9.3/v0.10.2 ------------------------ * Fixed bug that caused SASL mechanisms that require more than a single client response to fail. Reported by Steffen Kaiser and occured when he tried using the (obsolete) LOGIN mechanism. * Updated installation and configuration documentation to match the information provided in the wiki Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is finally available on the Dovecot wiki at: http://wiki.dovecot.org/ManageSieve New releases: 1.0: (patch) http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.13-MANAGESIEVE-v9.3.diff.gz http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.13-MANAGESIEVE-v9.3.diff.gz… 1.1: (package + patch) http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.2.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.2.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc4-managesieve-0.10.2.diff… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc4-managesieve-0.10.2.diff… (my public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net) Have fun testing the Dovecot ManageSieve service.

[Dovecot] Looking for suggestions: How to strip attachments from mails
by Patrick Nagel 20 May '08

20 May '08

Hi, I know this is not 100% on-topic, but I'll try anyway... I'm looking for a way to strip attachments from incoming mails on the server. The attachments should be stored on a file server (where users have access via SAMBA) and only a link to the file (UNC path) should remain in the mail body. This is to prevent the mail storage from filling up with a large amount of big mails where at the same time the 'payload' (attached file) is not conveniently accessible by the users. The current setup is postfix / dovecot deliver / dovecot (with sieve plugin). I'm considering piping the mails through something like mimeStrip.pl (http://freshmeat.net/projects/mimestrip.pl/) but therefore I'd probably need to bring procmail/maildrop into the game, right? Or are there other (better) ways to accomplish this?

[Dovecot] messages downloading repeatedly to mozilla/seamonkey pop3 client
by Ben Julian 19 May '08

19 May '08

Hello Dovecot List, I am a bit of a sysadmin novice and this is my first time emailing, so please let me know if I have left some critical information out. I am supporting a small office network supported primarily by linux servers. All of my users are using dovecot as a pop3 daemon on a centOS 5 box, no IMAP users. Seven users are running outlook 2003 on windows XP, two users are running thunderbird on ubuntu, two are running evolution on ubuntu, and one is running mozilla seamonkey on XP. Emails to the mozilla/seamonkey user are downloading multiple times, but not to any of the other users. A typical maillog report following this user's mail client pop3 login: Mar 3 10:37:00 servername dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=::ffff:192.168.99.13, lip=::ffff:192.168.99.4 Mar 3 10:37:00 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84873 > 84872, seq=2, idx_msgs=3) Mar 3 10:37:01 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84877 > 84872, seq=2, idx_msgs=4) Mar 3 10:37:01 servername dovecot: POP3(user): Disconnected: Logged out top=0/0, retr=1/3364, del=1/1, size=3347 Things I've tried: *adding the following lines to dovecot.conf: protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } *deleting the user's homedir mail directory (including all dovecot index files) *restarting dovecot *changing mail clients: tried outlook express, netscape 4.8, thunderbird on user's PC *restarting the server All changes resulted in only a brief (1-2hr) cessation of the problem. I've subscribed for a month or so now and searched the archives, but if I missed a solution to this in there, I apologize. Thanks, Ben Julian

[Dovecot] Fixed a Duplicate?
by Nigel Allen 19 May '08

19 May '08

Greetings We have recently switched from mbox to Maildir so that we can implement symlinks for a large email account that is shared (partially) between some 20 or so users. The setup is dovecot-1.0.3-6.fc6, procmail-3.22-17.1, sendmail-8.13.8-2. Procmail has a single recipe in /etc/procmailrc that simply says "DEFAULT=$HOME/Maildir/". The problem is that I am seeing a lot of blank emails being created. For exaample, every time I open a folder from this shared account, I get either one or two emails being created on the spot. The are /always/ created with the current date and time stamp (i.e. now) and at the same time a tail -f of maillog shows something like this: > May 19 09:10:05 sydsrv56 dovecot: IMAP(plans): Fixed a duplicate: > dovecot-shared:2, -> 1211152205.P10039Q1.sydsrv56 The only thing that appears to change is the last modified date and time of the two files, dovecot.index.log and dovecot.index.cache. Should I be maintaining separate index files or lock files for each user in this shared account? Currently the Maildir is shared and has the g+s bit set. Any ideas where I can start looking would be appreciated. Rgds Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Postfix & Dovecot LDA
by Jochen Schulz 18 May '08

18 May '08

Hi, before I start to write a lengthy email about something that isn't really possible anyway: can I make Postfix use Dovecot's LDA and start it with different user IDs? My scenario: Dovecot authenticates users for Postfix and itself using Postgresql. Mails for two domains should be stored under /srv/<domain>/<user> (which is the location returned by my user_sql query and mail_location). When my clients login (with usernames of the form 'user@domain'), Dovecot creates/opens the correct mailboxes for them, but I can't get LDA to deliver to these mailboxes. Whatever I try, I am always running into some kind of permission problems (either for the mailboxes, or for auth_socket). I want to use a unique UID for every virtual domain, so I guess LDA needs to have permissions for every corresponding mailbox *and* Dovecot's auth_socket_path. Is there a good solution for this which doesn't involve severe security implications? J. -- If all my friends had Playstations I would buy a Nintendo to prove my individuality.

[Dovecot] Security Hole in 1.0.13?
by Lawrence Sheed 18 May '08

18 May '08

I'm running 1.0.13 If I run dovecot for a while, I see a /var/run/dotvecot folder created with the following: drwxr-xr-x 3 root root 4096 2008-05-18 13:30 dotvecot drwxr-xr-x 3 root root 4096 2008-05-18 13:47 . drwxr-xr-x 18 root root 4096 2008-05-18 13:47 .. srw------- 1 root root 0 2008-05-18 13:47 auth-worker.15138 srwxrwxrwx 1 root root 0 2008-05-18 13:47 dict-server drwxr-x--- 2 root dovecot 4096 2008-05-18 13:47 login -rw------- 1 root root 6 2008-05-18 13:47 master.pid It appears to be created by imap-login I've tried removing any dovecot remnants and reinstalling from the 1.0.13 tar.gz from the site. After starting dovecot again after a few minutes the files appear. The processes are running something on 6243 and 6244 (Presumably an exploit / login) I have iptables setup to only allow existing ports in/out so I think thats saved me so far. I've switched to courier-imap in the interim. Anyone want to assist in finding out how they are getting in? Definitely dovecot related. If I don't run dovecot, seems secure.

[Dovecot] Development news
by Timo Sirainen 17 May '08

17 May '08

First a list of all the new features and their state: 1. http://hg.dovecot.org/dovecot-threadindexes/ THREAD=REFERENCES indexes. Missing NFS flushes, support for mmap_disable=yes, breaks when more than one session modifies at the same time. Not tested much if the replies are really correct at all. Also started THREAD=X-REFERENCES2 but it doesn't work as expected. 2. http://hg.dovecot.org/dovecot-virtualboxes/ Virtual mailboxes. Nothing changed since http://dovecot.org/list/dovecot/2008-March/029546.html 3. http://hg.dovecot.org/dovecot-condstore/ Implemented CONDSTORE, QRESYNC, ESEARCH, SEARCHRES and WITHIN extensions. The only known problem left is making CONDSTORE's STORE UNCHANGEDSINCE operation atomic, but it requires changing transaction log file format. Maybe I'll do it and just make v1.1 and v1.0 be able to read the format and just ignore the modseq in the record. Those code trees don't contain all the latest changes from v1.1 tree. So at some point I'll start merging all of them into one dovecot-1.2 code tree. v1.1 is coming along pretty nicely. I'll make a new RC release in a few days. After that probably one more and then v1.1.0. Tomorrow begins a 5 week lab course at school. Every day and about 8 hours a day. And then we'll also have to write these reports about what we have done and how/why, which takes quite a lot of time as well. After 5 weeks there's one free week and then probably another 2 week lab course if I get selected there. So I doubt I can get much Dovecot work done for the next two months. It's also likely that I won't be answering mails much in this list either.

[Dovecot] mysql index control allow nets
by Evaggelos Balaskas 16 May '08

16 May '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, I am using dovecot 1.0.13 with sieve plugin, index, control and allow nets in my userdb per user. I am trying to have the same configuration with dovecot 1.1 and MySQL. According to log files when a virtual user is connecting to dovecot, the dovecot reads from MySQL the correct values but dovecot doesnt create the dirs for INDEX, CONTROL and the allow_nets is bypasses. - From my logs : dovecot: May 14 20:56:23 Info: auth(default): master out: USER 12 ebalaskas(a)ebalaskas.gr uid=1002 gid=8 mail=maildir:/var/mail/ebalaskas.gr/ebalaskas INDEX=/var/mail/.index/ebalaskas.gr/ebalaskas CONTROL=/var/mail/.control/ebalaskas.gr/ebalaskas allow_nets=10.10.10.192 The connection is ok (i tested via telnet and webmail) but my IP is : 10.10.10.102 and there isnt any /var/mail/.index/ebalaskas.gr/ebalaskas or /var/mail/.control/ebalaskas.gr/ebalaskas folders The only thing is the folder : var/mail/ebalaskas.gr/ebalaskas the dovecot-sql.conf is correct (you can see this from my logs) so what is wrong ???

[Dovecot] Sieve plugins 1.0.3 and 1.1.5 released
by Timo Sirainen 16 May '08

16 May '08

http://dovecot.org/releases/sieve/dovecot-sieve-1.0.3.tar.gz http://dovecot.org/releases/sieve/dovecot-sieve-1.0.3.tar.gz.sig http://dovecot.org/releases/sieve/dovecot-sieve-1.1.5.tar.gz http://dovecot.org/releases/sieve/dovecot-sieve-1.1.5.tar.gz.sig I've usually released new Sieve plugins at the same time as new Dovecot versions, but since I wasn't planning on releasing v1.0.14 anytime soon and it looks like v1.0.2 release was quite a while ago, I decided to release these today. Changes: - Improved vacation reply checks, log discarded vacation replies (in v1.0.3, these were already in v1.1.0) - Expand ~ to home directory in sieve path - If compiled script has the exact same mtime as the source script, assume the script hasn't changed (changed "<" check to "<="). - Unfold multiline headers before comparing them. - Improved error logging.

[Dovecot] deliver exits with status 89 on some but not all mails of a batch
by Patrick Nagel 16 May '08

16 May '08

Hi, I'm trying to get dovecot's LDA 'deliver' to deliver mails that come in through a postfix daemon on the same box. I'm talking about dovecot version 1.0.rc15 (on CentOS 5 as Linux-VServer guest on a CentOS 5 host). Configuration ------------- # /etc/dovecot.conf ssl_cert_file: /etc/pki/selfmade/server.crt ssl_key_file: /etc/pki/selfmade/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login verbose_proctitle: yes mail_extra_groups: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: verbose: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot dovecot-ldap.conf looks like this: uris = ldap://dbserver dn = cn=dovecot,ou=services,dc=company,dc=net dnpass = secret ldap_version = 3 base = ou=people,dc=company,dc=net scope = onelevel user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = LDAP-MD5 postfix has mailbox_transport set to dovecot, and master.cf contains the following: dovecot unix - n n - - pipe flags=DRhu user=fry:fry argv=/usr/libexec/dovecot/lda/deliver -d ${recipient} Problem ------- When a lot of mails come in 'at the same time', for example because an employee mailed all other (local) employees, the following happens: Some mails are being delivered as advertised, but on some mails, deliver exits with status 89 and the message bounces.

Hello, I run a debian etch server with the mail services configured like their: http://workaround.org/articles/ispmail-etch/ It worked during month but of the last upgrade it doesn't work anymore when postfix calls deliver. dovecot version is 1.0.rc15.

[Dovecot] moving folders bug - rc4
by Anil 15 May '08

15 May '08

I am fairly new to dovecot... I had a user who in outlook tried to move one of the folders into another folder but it crapped out. User tried to move "Djans*" folders into Koi folder. The subscription seems to show the folder move but the actual data is still under ".ClickEats.Clients.Djans" instead of ".ClickEats.Clients.Koi.Djans*. How do I fix this? Thanks. root@the:/apps/mail/clickeats.com/juliam/Maildir# grep -i djan subscriptions ClickEats.Restaurants.Djan's ClickEats.Clients.Koi.Djans.Online Orders ClickEats.Clients.Koi.Djans root@the:/apps/mail/clickeats.com/juliam/Maildir# ls -a |grep -i djan .ClickEats.Clients.Djans .ClickEats.Clients.Djans.Online Orders .ClickEats.Restaurants.Djan's root@the:/apps/mail/clickeats.com/juliam/Maildir#

[Dovecot] Automounted home dirs not working
by Roy McMorran 15 May '08

15 May '08

I'm testing Dovecot as a possible replacement for UW. In my environment the home directories are automounted via NFS from a NetApp. In general this works fine, but Dovecot isn't picking up the automounted directories. Consider the case of Arthur Dent, test user: May 12 10:30:24 testbed dovecot: [ID 107833 mail.info] imap-login: Login: user=<adent>, method=PLAIN, rip=xxx.xxx.xxx.242, lip=xxx.xxx.xxx.242, secured May 12 10:30:24 testbed dovecot: [ID 107833 mail.error] IMAP(adent): mkdir_parents(/home/adent/Mail) failed: No such file or directory May 12 10:30:24 testbed dovecot: [ID 107833 mail.error] IMAP(adent): Mail storage creation failed with mail_location: mbox:/home/adent/Mail:INBOX=/var/mail/adent May 12 10:30:24 testbed dovecot: [ID 961074 mail.error] child 21816 (imap) returned error 89 (if however I make sure that /home/adent is mounted at the server (eg. cd /home/adent) prior to starting the mail client this error does not occur) Why isn't the automount succeeding? This is Dovecot Version 1.0.13. I'm running under Solaris 10. Thanks!

Its not always because someone was lazy about > their time setup. My point exactly. It's amazing how some people are quick to ramble about someone else's administrative incompetence without taking time to read the situation. (One person even suggested hacking the dovecot startup script to run ntpdate -- useless as ntpd already occupies the ports). Fact is, ntpd can take unpredictable delay before the initial time-step. Delay that can't be controlled, and it would be unreasonable to delay starting mail services until it is guaranteed to complete. Then, dovecot dies, and admin (who is not always immediately available) has to start it manually anyway (especially as it is not clear what to do with possibly unsynced timestamps) -- only after the unnecessary downtime. So, the question is: why on earth can't we add a single line of code to dovecot to restart itself after terminating? Kind of reminds me of the "fsck_y_enable=YES" option in rc.conf. Without it, if fsck does not like someting during reboot, the server would just sit there in single-user prompt, waiting for (expensive) console operations. Best wishes Eugene

[Dovecot] Allow_nets + MySQL failing when using range notation
by Javier García 15 May '08

15 May '08

Hello all, I am testing my dovecot installation in order to restrict access via POP3 for IPs outside my network. I have read and understood the instructions in the wiki and I have reached a configuration that works ONLY when single IPs are listed in allow_nets but not when ranges in the notation x.x.x.x/y are listed. Some examples should be more explanatory. I am using 1.0.rc15 patched as for last week as distributed in Debian etch. First of all, everything related to this is stored in a MySQL database, here is my password query: password_query = SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.%Ls = 1 ) and u.mail = '%u' This one should validate all mail addresses when the protocol used is marked as 1 in table access_type and when the allow_nets value in this same table contains the IP used for the access request. The, if access_type looks like: ID_access pop3 imap allow_nets 3 0 1 10.34.128.0/23, 10.34.133.0/24, 192.168.0.0/24 users with ID_access=3 fail to login by either pop3 (normal, value is 0) or imap. Here is the corresponding excerpt from dovecot.log: dovecot: 2008-03-31 11:29:04 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.imap = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 192.168.0.0/24 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.128.0/23 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.0/23 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): passdb(user(a)domain.com,10.34.133.104): allow_nets check failed: IP not in allowed networks but if it looks like ID_access pop3 imap allow_nets 3 0 1 10.34.133.105, 10.34.133.104 then access is allowed by IMAP dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.imap = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.105 dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.104 dovecot: 2008-03-31 11:34:01 Info: auth(default): client out: OK 1 user=user(a)domain.com while POP3 still disallowed as expected: dovecot: 2008-03-31 11:34:25 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.pop3 = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:34:25 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): unknown user So, is there a bug related to the IP class notation or am I doing something wrong? I have tried to leave a single class (10.34.133.0/24), to explicitly erase any spaces after the commas, but nothing of these worked. Also, note that using 0.0.0.0/0 behaves as expected, this is, access for any IP is allowed. Thanks in advance, Javier

[Dovecot] Mixed maildir and mbox folder

Hello, i tried to implement a mixed structure of mbox for spams and spam backscatters and maildir for the rest at dovecot 1.0.13. I used the information at the dovecot wiki: http://wiki.dovecot.org/Namespaces (Multiple Mailbox Locations) But if i try this (complete config is attached with this part) namespace: type: private separator: / prefix: "#md/" location: maildir:/srv/imapd/user/%u/maildir inbox: yes hidden: yes namespace: type: private separator: / location: mbox:/srv/imapd/user/%u/Spam thunderbird can't open a maildir folder:-( The msg is " Mailbox doesn't exist: XXXX" If i use this version: namespace: type: private separator: / location: maildir:/srv/imapd/user/%u/maildir inbox: yes namespace: type: private separator: / prefix: "#mb/" location: mbox:/srv/imapd/user/%u/Spam hidden: yes Thunderbird can open maildir folder but no mbox folder.. " Mailbox doesn't exist: XXXX" :-( Where is my fault? Or is this feature first complete implemented at 1.1?

[Dovecot] homedir override problem, MS AD + WINBIND + PAM + SIEVE
by Milan Koudelka - Internet Mall 15 May '08

15 May '08

Hello, i installed my Dovecot with authetification in MS AD throught WINBIND and PAM. Works fine. So I have virtual users with UID, GID from MS AD. I set maildir path as mail_location = maildir:/var/spool/mail/%n/ Then i want to make some vacation system. I install sieve and use dovecot LDA. In postfix main.cf I have mailbox_command = /usr/libexec/dovecot/deliver Setup of lda in dovecot.conf protocol lda { postmaster_address = postmaster(a)mail-server.cz log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log mail_plugins = cmusieve } Sieve user-scripts doesn't work without this: plugin { sieve = /var/spool/mail/%n/.dovecot.sieve } With this settings, LDA and sieve works OK. I can use user-scrips to forward mail by subject or something like this. Vacation rules works too. But it isn't create .dovecot.lda-dupes in user home directory that contains e-mail addresses that was replied. So vacation is sent always. I have this error in dovecot-deliver.log deliver(mkoudelka): May 14 12:24:19 Error: open(/home/MALL/mkoudelka/.temp.cz-dc1-s-018.mall.cz.11302.7e2cc05a1e1df1a7) failed: No such file or directory I tried to override home directory by set this: userdb passwd { args = home=/var/spool/mail/%n } But there isnt't any change. Can you please, help how to set correct home for sieve ? MALL is domain of user mkoudelka. Thank you -- Milan Koudelka Linux & Network Administrator Internet Mall, a.s.

Hello, I'm seeing some messages from dovecot in my logs such as: May 8 11:43:41 snowdrift dovecot: IMAP(username): Disconnected: BUG: Unknown internal error I did some searching, and discovered a similar report last month, to which there was a request for more information that didn't seem to get followed up, so I have collected this information too. Dovecot version: 1.0.10 (from Ubuntu hardy package, which includes some patches; details of the patches can be found here: http://svn.debian.org/wsvn/collab-maint/deb-maint/dovecot/trunk/debian/patc… ) OS: Ubuntu 8.04 (Hardy) CPU: x86 Filesystem: ext3 IMAP client: Thunderbird. What was happening with it is not too clear, unfortunately it only seems to occur for one user, and that's not me. Reproducability: Seems to occur fairly frequently, but unable to provide steps. dovecot -n output: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s ssl_cert_file: /etc/ssl/certs/snowdrift-cert.pem ssl_key_file: /etc/ssl/private/snowdrift-key.pem ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd Raw log output: 29 OK Fetch completed. * 632 FETCH (UID 14265 RFC822.SIZE 4373) * BYE BUG: Unknown internal error Immediately before that was a set of headers from an email, so I guess that's what the "29" line's talking about, and it's just the last two that are relevant. Please let me know if there's anything further I can provide to help track this down. Thanks, Ainsley

[Dovecot] unix style mbox and vmain maildir on the same server
by Glen Lee Edwards 15 May '08

15 May '08

Hi, I'm new to dovecott. Using version 1.0.rc15. I have a mail server that has both the old style unix mbox in /var/mail/%u, and virtual mail maildir in /var/vmail/%d/%n. Debian Linux Etch stable. I'm trying to get dovecot to deliver to /var/mail/%u using mbox format, and to deliver to /var/vmail/%d/%n using maildir format. I can't get it do work. I can get it to access both directories, but not use the two formats. This is what I tried last: namespace private { separator = / inbox = yes hidden = yes prefix = location = mbox:~/mail:INBOX=/var/mail/%u } namespace private { separator = / inbox = no hidden = yes prefix = mail/ location = maildir:/var/vmail/%d/%n } I have since commented out the above two namespaces and set mail_location to mail_location = maildir:/var/vmail/%d/%n. $ dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login passdb: driver: pam args: dovecot passdb: driver: passwd args: blocking=yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=2000 gid=2000 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail Glen

[Dovecot] Problem with virtual mail user login users uid not permitted

14 May '08

Hello, I am trying to run exim 4.68 and dovecot 1.0.13 on Solaris 10 x86 5/08 using dovecot lda and sieve with virtual users and domains, tls and ssl. At the moment certificates are from my internal CA Exim and Dovecot, dovecot lda and dovecot sieve were downloaded and installed from Blastwave. Mail delivery (ie from Exim to dovecot via dovecot lda) is working correctly but when I try to access mail using imap from a client (eg. Thunderbird) the login fails. My mail user for accessing virtual user mail is vmail (uid=954, gid=954). I have attached the messages from dovecot.log and the output of dovecot -n below as well as contents from the passdb file.

[Dovecot] Time moved backwards
by Eugene 13 May '08

13 May '08

Hello, I would like to suggest a change in handling of 'Time moved backwards' problem. Right now dovecot just dies. So, the scenario: 1) Colocation server is shut down for some reason. The internal time drifts. 2) Server is started again. 3) Dovecot starts successfully. 4) In about a minute, NTP daemon feels confident about adjusting the system time. 5) Dovecot sees the changed time and dies. 6) Admin has to notice that, login and restart Dovecot manually. I suggest that Dovecot simply terminate the current connections (causing the client to reconnect) or -- if the time change is really that much of a problem -- to restart itself automatically. Maybe a config option could be introduced. Best wishes Eugene

[Dovecot] Access to the root of a shared mailbox

A must have an access to all mail of B So i create a public namespace namespace public { separator = / prefix = Public/ location = maildir:/home/users/B/Maildir } It's OK for the subfolders, but not for the root (B's inbox, the most important !) it's seems to be like http://www.dovecot.org/list/dovecot/2007-October/025965.html it's the only feature that prevents me to migrate from Courier-IMAP !

12 May '08

Hi All, I'm trying out the imapsync migration tool, migrating user mails from cyrus IMAP to Dovecot IMAP. In order to avoid knowing about each of the users password, I use the cyrus admin user in the cyrus end. Is there such a thing as the dovecot admin user, or is that simply the root user? Any input appreciated /Lars

[Dovecot] imap memory footprint rather large
by martin f krafft 12 May '08

12 May '08

Dear list, I am experimenting with a new mail handling setup and it involves a single IMAP folder with just under 70'000 messages. When OfflineIMAP connects to the server, the imap process starts to eat up a lot of memory: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 15607 madduck 35 19 283m 244m 239m D 16.9 49.3 0:09.96 imap On the contrary, when "online" client, such as Thunderbird connect, memory usage is around 10m, which is entirely acceptable. The way offlineimap reads may is by FETCHing metadata, then APPENDing new local mail, SEARCHing for the UIDs of each uploaded mail, and finally FETCHing new remote mail. Memory use seems to be O(n) in the size of the folder. On the folder with 70k messages, dovecot seems to allocate 280m of memory, which it then fills to about 70% during the metadata FETCH, and then keeps growing while APPEND/SEARCHing the new local messages. The 70k mailbox is just short of 600Mb in size on disk. Dovecot uses 280Mb to serve it. Is it possible that dovecot is reading too much into memory, or over-optimising? Can I somehow tweak this to lower the memory footprint? Cheers, -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck "the unexamined life is not worth living" -- platon spamtraps: madduck.bogus(a)madduck.net

[Dovecot] Another numptie question - making maildirs for shared mailboxes.
by Stroller 12 May '08

12 May '08

Hi there, Sorry to have so much trouble with my Dovecot setup & to ask so many questions, but I'm having some problems with shared folders. I've read the thread at <http://dovecot.org/pipermail/dovecot/2005-January/006079.html> and added the following lines to /etc/dovecot.conf: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = General/ location = maildir:/tmp/dovecot-test/ inbox = no hidden = no } So I create a directory /tmp/dovecot-test/ and an empty file /tmp/dovecot-test/dovecot-shared with liberal (777 & 666 respectively) permissions and then try to subscribe to the "General" folder in Outlook - I get a "failed to subscribe to the folder. The server responded `the mailbox doesn't exist: General`" error message, but cur, new & tmp are created in /tmp/dovecot-test. These subfolders are owned by the user that attempted to subscribe & have 700 permissions; chmod'ing them 777 makes no difference. Since "default_mail_env = maildir:%h/.maildir" in dovecot.conf I make a directory /tmp/dovecot-test/.maildir also containing cur, new, tmp & dovecot-shared. When I select "IMAP folders" in Outlook I am still unable to subscribe to "General" but am now able to subscribe to "General/maildir". The subscribed folder is shown in Outlook underneath the users' Inbox as a sub-folder of general, screenshot at <http://linux.stroller.uk.eu.org/DovecotSharedFolders.png> - see how I can't subscribe to "General" alone, but it is "brought in" by subscribing to "General/maildir"? If I try to copy a test message into General then, after a delay of a minute or so, I get "Can't move the items - this IMAP command could not be sent to the server before the connect was terminated"; if I try to copy the test message into General/maildir then I immediately get "Can't copy the items. The server responded: `Internal error occurred. Refer to server log for more information [2005-12-20 12:05:40]". I've tried tinkering with other directory structures under /tmp/dovecot-test/ with no success - can anyone suggest what I'm doing wrong, please? It's quite important to me that the "General" folder is a fairly high-level one - only one additional folder icon should show up for the users' shared mail. At one point I managed to create a folder General/General, but that's undesirable - the users wouldn't understand the concept of having a folder showing in Outlook that they can't write to, or which is only used as a container for another folder. (In any case, I believe I was still unable to write to it). I was about to say, "I know I could resolve this with the use of a symlink-type shared folder, but that's undesirable because I'd have to manually add the symlink for each user that's added to the system", but writing this it occurs to me that I could resolve that by adding the symlink to the the etc/skel/. Nevertheless, I see the namespaces approach as more elegant, as it allows for different user groups having different shared folders. I'd appreciate any advice - I suspect I'm just getting the directory hierarchies wrong, or the syntax of dovecot.conf wrong AGAIN! If anyone with a working shared folders setup could provide a copy of the appropriate section of dovecot.conf & a listing of the appropriate directories then I'd be EXTREMELY grateful. Stroller.

[Dovecot] how add size and vsize filed to a maildir filename ?
by Marco Giunta 12 May '08

12 May '08

Hi to all, I'm a sys admin in a college, and we're using Dovecot as IMAP/POP3 server and delivery; we're also patch dovecot to add managesieve capability. I've a question: I've read on dovecot's wiki, that is possible improve the performance on maildir file by adding ,S=<size>,W=<vsize> fields on filename. How is possible to do that ? I've search on all the wiki and on the mailing list, but I didn't find nothing about modify the maildir file name. Someone can help me ? Best regards, Marco

[Dovecot] IMAP, Shared folders, symlinks and permissions
by Nigel Allen 12 May '08

12 May '08

Greetings Using FC7, dovecot-1.0.3-6.fc6 and maildir I have a recurring problem with permissions. We have a (real) account on the system called "custs". Within the email account for custs there exists some 300 folders, one for each customer. This worked okay originally with mbox. Everyone had access to their own email folders and they all had access to the "custs" account. They only problem is that to find one folder (customers)'s emails, you had to scroll through 300+ folders. For the people who need access to all of the custs' folders, there was no problem (apart from a real estate one of scrolling which sometimes caused people to drag and drop into the wrong folders). The problem is that around 16 staff need only access to a subset of customers (i.e. the ones they manage - around 20 each) while the rest of the staff need access to the lot. What we did was to convert everything to Maildir so that we could use symlinks. So far so good. We created symlinks from /home/custs/Maildir/customer1 to /home/manager1/Maildir/customer1 and from /home/custs/Maildir/customer2 to /home/manager2/Maildir/customer2. Again, so far, so good. Manager 1 gets access to Customer 1 and Manager 2 gets access to Customer 2. The problem comes when someone who ONLY has access to the "custs" account drops an email into Customer 1. The file dovecot-uidlist gets created and suddenly Manager 1 cannot see the folder. We changed (in desperation) the group owner of custs/Maildir to "common" (which everyone is a member of) and did a chmod g+s from the custs/Maildir down. e even set the permissions of the custs/Maildir/* to 777 to watch what was happening. It appears that the permissions on the file dovecot-uidlist is set to 600 every time someone drops an email into the folder. Then when someone else tries to access the folder they get a "permission denied" error on dovecot-uidlist. Can anyone explain to me how to: Change the way dovecot creates the dovecot-uid files so that the permissions are set to 660 or 666 or Set this up better so that we can share all these folders. Any suggestions, questions, comments will be (very) gratefully accepted. Rgds Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] BUG: Bad grep when building dovecot?
by Andrew Lentvorski 12 May '08

12 May '08

Is dovecot *really* that picky about grep, or did it just happen to pick up an autoconf that's being overly pedantic? I saw this message a couple of times when googling, but no particularly good solution presents itself. I'll probably give it a new GNU grep just to get it to shut up, but I'm a bit surprised. I tried to compile dovecot in an OpenSolaris 2008.5 system in a zone (which is quite a bit more minimal than base OpenSolaris). bash-3.2# uname -a SunOS postfix-s0 5.11 snv_86 i86pc i386 i86pc bash-3.2# ./configure --help `configure' configures dovecot 1.0.12 to adapt to many kinds of systems. bash-3.2# which grep /usr/bin/grep bash-3.2# grep -v Usage: grep -hblcnsviw pattern file . . . bash-3.2# which egrep /usr/bin/egrep Error in configure: checking for cc option to accept ISO C89...

[Dovecot] MBOX to Maildir preserving the UIDL (outlook-tested, no redownloading)
by Horn Wijaya 09 May '08

09 May '08

TESTED AND RUNNING, MIGRATING from MBOX to MAILDIR, PRESERVE UID and OUTLOOK sees the email as downloaded. I hope this helps a lot of people out there. Feel free to post this somewhere else too. By: Horn Wijaya (hwijaya(a)nodens.biz) 8th May 2008 I have been searching for weeks for a foolproof method to migrate all my users mbox to maildir/dovecot without having the pain of downloading all emails again, especially for heavy users. It would cause frustration to thousands of my users. So.... eventually I found out why Outlook will keep downloading the emails despite all the configuration done in the dovecot.conf. Apparently the UID is generated realtime. When it first generated, it took the time the process runs. Before I migrate, here's the email sample which I have downloaded to my outlook (and keep email on server), and then I use telnet to pop to get the uidl list. +OK POP3 localhost.localdomain v2003.83rh server ready user ***** +OK User name accepted, password please pass ***** +OK Mailbox open, 444 messages uidl +OK Unique-ID listing follows 1 47b1303d00004c2d 2 47b1303d00004c2e 3 47b1303d00004c2f ... 47b1303d = 1202794557 = 12 Feb 2008 13:35:57 the date and time the mbox was created 00004c2d = 19501 the IMAP counter so far.... sequently added as you could see with email #2 and email #3 Then I switch my POP server to dovecot, and migrate my MBOX to Maildir, and I do a telnet to get the UIDL +OK Dovecot ready. user ***** +OK pass ***** +OK Logged in. uidl +OK 1 4822815000000001 2 4822815000000002 3 4822815000000003 ... 48228150 = 1210220880 = NOW 00000001 = counter starts at 1 No wonder outlook sees the emails are NOT-DOWNLOADED-YET status. Then I ponder for another few days and the key is in the dovecot-uidlist...... How to fill it with the correct info.... and there's a way. Which I hope useful for converter developer, and could be implemented in the next version of the converter. Here's the step I do to reach my objective which is to get UID 47b1303d00004c2d in the first email: 1. mb2md-3.20.pl -s /var/mail/hwijaya -d home/hwijaya/Maildir/ that's converting 444 emails from mbox to 444 files in the Maildir/cur folder 2. cd /home/hwijaya/Maildir/cur 3. grep IMAPbase * and I get 1210219860.000000.mbox:2,S:X-IMAPbase: 1202794557 19944 The last 2 strings are the KEY to the ORIGINAL UID 4. So in order to prepare the environment to fool it, some calculations are needed: How do we get 19501 as the first counter? as expected in the first POP TEST above: 19944 - 444 emails + 1 = 19501 5. cd /home/hwijaya/Maildir 6. echo '3 V1202794557 N19501' > dovecot-uidlist 7. DONE....... pop it via outlook and nothing will be downloaded, after pop or imap is processed, the dovecot-uidlist is auto-filled, index auto generated. Proof: +OK Dovecot ready. user ***** +OK pass ***** +OK Logged in. uidl +OK 1 47b1303d00004c2d 2 47b1303d00004c2e 3 47b1303d00004c2f ... I assume the same method could be used for individual folders in the imap (under .mailboxlist or .subscriptions) Please do let us know if there's any cases/environment that it won't work. Thanks very much, and a big migration job is in front of me now... ------------------------------------------ Warmest Regards From: Horn Wijaya Consultant hwijaya(a)nodens.biz http://www.nodens.biz/ Nodens Solutions Pte Ltd "where there is freedom in your choice"

[Dovecot] [Q] IMAP update message header?
by Roderick A. Anderson 08 May '08

08 May '08

More about IMAP, less about Dovecot. This is more an IMAP question than specifically about Dovecot. Sorry to ask here but I've been researching, reading and lurking with no answer so far. What I'm doing is running reports as a user from a remote system to provide a list of messages (Sender/From, Subject, Date, size) in a specific folder(?). In one case it isn't even a Dovecot based server so I only have access as a client. (Though I use Dovecot on several other systems and will need this capability for them.) When a message in the folder has been reported I'd like to add a X-Header-??? indicating that the message has been reported so the next time through it isn't reported again. (After the message is X days old it is deleted.) These reports are run using Perl and I've tried most every CPAN module available but haven't figured out how to change/add a header then save the message back. So far I haven't been able to determine if this is even possible by reading the RFCs. Is there a method as a client from a remote system to make changes to a message then save it back? What is the IMAP verb, command, etc. to do this? Or if there are Perl programmers on the list a brief description (or code) for doing this? TIA (and sorry for the off topic posting), Rod --

Not true! simple way: Just change the default config TB create your account from with the settings you need. You can find the file under your program dir i.e. C:\Programme\Mozilla Thunderbird\defaults\pref Compare the defaults to your working set of setting and change them accordingly.

[Dovecot] Clarification wanted on mail_access_groups vs. mail_privileged_group
by Mark Sapiro 07 May '08

07 May '08

I have just upgraded to dovecot 1.0.13. All the documentation I can find in the example .conf file and the NEWS and ChangeLog files seems to say that the mail_privileged_group = mail setting is all I should need to make dovecot use group mail to create dotlock files. My understanding from what I read is that mail_privileged_group is used to set the group used while creating dotlock files in (in my case) /var/spool/mail, and mail_access_groups is used to set the group used to actually access the mailbox. In my case, /var/spool/mail is group 'mail and group writable/searchable drwxrwxr-x 2 root mail 4096 May 7 08:35 /var/spool/mail and the individual mailboxes are owned by the respective users. So it seems that I would need "mail_privileged_group = mail" do be able to create dotlock files in /var/spool/mail, and that I would not need any mail_access_groups as the users can access their own mailboxes. But this doesn't work. With "mail_privileged_group = mail" and mail_access_groups unset, I get May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Yet with "mail_access_groups = mail" and mail_privileged_group unset, it works with no problem. Is my understanding wrong? Is the documentation wrong? Is the implementation wrong? Or is there just something wierd in my case (possibly pop3_lock_session = yes)? # dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf protocols: pop3 pop3s ssl_cert_file: /etc/postfix/grizz-cert.pem ssl_key_file: /etc/postfix/grizz-key.pem login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_access_groups: mail mail_location: /var/spool/mail/%u mbox_write_locks: fcntl dotlock mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] dovecot pop3 proxy with AUTH PLAIN
by Luis Barrueco 07 May '08

07 May '08

Hi, I tried as hard as I could, but I couldn't get this working. So here I come begging for help :) I need to configure dovecot to proxy some users' incoming pop3 connections to another server running the Zimbra Collaboration Suite, trying to log into zimbra via a master password. The problem I found is that zimbra only allows me to log in as a master user with the "AUTH PLAIN" mechanism, but it seems that dovecot uses the "USER.... PASS" authentication when proxying. Am I missing something? Has anyone ever tried to do the proxy+master password to zimbra? I'll post my configurations down here. I really appreciate your help- ----------------------------- dovecot version: 1.0.13 ----------------------------- "dovecot -n" output: # 1.0.13: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd ----------------------------- /usr/local/etc/dovecot-sql.conf: driver = mysql connect = host=172.16.0.252 dbname=dovecot user=usuario_dovecot password=miclave password_query = SELECT password, 'secret_zimbra' as pass, host, destuser, 'Y' AS proxy FROM proxy WHERE user = '%u' ----------------------------- sudo tcpdump -w output_tcpdump -i eth0 dst host 172.16.0.20 and dst port 110: .........USER mnunez master ......... .........PASS secret_zimbra ----------------------------- I hope this information was helpful!

[Dovecot] FETCH for mailbox INBOX UID 5003 got too little data: 5369 vs 38919
by Adam McDougall 07 May '08

This happened a while back, I was running 1.1rc3 up until today so I have no idea if it would have an effect. Sorry if its something that has been fixed. The error below was repeated many many times, I deleted the index so the user would stop getting disconnected (although I didn't hear any complaints).

[Dovecot] dovecot + exim + verify recipient / reject bad recipient at SMTP time
by Peter Hudec 07 May '08

07 May '08

hello, I'm quite new to dovecot. My instalation is working good Debian Etch - exim: 4.63-17 - dovecot: 1.0.rc15 I'm using virtual user setup, with LDA delivery method. There is no database backend at this time. Is there any way to configure exim to reject non-existing user /asking dovecot lda/ at SMTP time. The standard exim configuration in ACL section do not work: --- cut --- require message = e-mail address is not valid ($local_part@$domain / $recipient_verify_failure) domains = +virtual_domains verify = recipient --- cut --- Please, have any work working example ? This setup work good witch cyrus-imap and LMTP. best regards Peter Hudec

[Dovecot] Manual thread breaking from Thunderbird
by Christian Jaeger 07 May '08

07 May '08

Hello I'm looking for a way to manually break threads apart when independent threads are mixed up, mostly by users which aren't aware that they should not be replying to existing threads when starting a new one. Since Thunderbird afaik does the threading itself, it would require a solution that actually changes the In-Reply-To header (and maybe also that other (non-standard?) header which is being sent by the M$ clients). For me modifying the actual emails on disk would be fine, i.e. renaming the In-Reply-To header to Old-In-Reply-To and such. (I'd actually *prefer* a solution that modifies the server side store, as opposed to one which keeps that info on the client side only like mutt seems to be doing.) Is there a way to do this already? Seems like a task for a dovecot plugin--or for the xexec plugin and an external perl script or some such? For triggering the renaming, a hacky solution could be to misuse labels (e.g. marking a message starred and "Later" and "Important" at the same time would trigger the modification and remove the labels). When implementing such a thing: maybe also offer a way to modify subjects (for those cases where people are using short meaningless and recurring subjects--to both help breaking up the ensuing threading as well as giving them a useful replacement), maybe as an IMAP extension or such (to be used by Thunderbird plugins (?), or by web apps). (I can code in C and Perl, but don't generally have much time.) Christian.

[Dovecot] Question about Maildir automatic cleanup.
by José Ildefonso Camargo Tolosa 07 May '08

07 May '08

Hi! I want to automatically delete old messages from one user's Maildir, and I was thinking on running something like this: find /home/user/Maildir/cur/ /home/user/Maildir/new/ -daystart -mtime +15 -delete but I'm not sure if by deleting messages "manually" I will break the dovecot.index* files. What do you think? Thanks! Ildefonso. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

[Dovecot] 1.07 to 1.0.13 mail_extra_groups
by Mark Sapiro 06 May '08

06 May '08

I have just upgraded from 1.0.7 to 1.0.13. I read the comments in the example .conf file and it seemed what I needed to enable dotlock access to mailboxes in /var/spool/mail (writable by 'mail' group) was "mail_privileged_group = mail" so I removed the "mail_extra_groups = mail" that I had in 1.0.7 and added "mail_privileged_group = mail", but I got errors like the following: May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-05-06 12:48:54] May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 May 6 12:48:54 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured I then put "mail_extra_groups = mail" back in the configuration. This seems to have the effect of setting both "mail_privileged_group = mail" and "mail_access_groups = mail" as well as issuing "Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead" when dovecot is started. So my question is what do I need. I thought it would be just "mail_privileged_group = mail", but that doesn't work. Do I need both "mail_privileged_group = mail" and "mail_access_groups = mail" or just "mail_access_groups = mail". Also, are the comments describing these in the example .conf file correct, or are they reversed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] deliver custom maildir creation
by Steve Roemen 06 May '08

06 May '08

/ I'm testing a new setup of postfix using deliver to put the messages into the user's maildir, and am curious if there is a way to make deliver create custom maildirs when it delivers to a valid user without a maildir? Right now it only creates the inbox, I'd like it to create the .sent/ .Trash/ and .SPAM dirs. Is this possible? Thanks -------------------------------------- / /Steve Roemen// /

If the user received new mail on the new system, say, around 200kb, and then he/she logs in, messages from the old system are copied. If he had 100Mb of mails (old system), and quota is 20Mb, only the 200kb are shown. Dovecot was not restarted. The problem was what you pointed out, maildirsize had to be deleted, then everything seems to be ok - getquotaroot indicates 100Mb + 200kb. > How badly wrong is the quota?

[Dovecot] imap fs quota (rpc) won't work?
by Adam McDougall 06 May '08

06 May '08

In the past I dabbled with the imap quota plugin with the fs backend because I wanted to report usage to my users (not limit them). At the time, the quota plugin would make dovecot crash when trying to write to a folder (I can bring up this report if needed). However, in a later beta of dovecot 1.1 I tried quota again but I cannot get it to report any results. I've been wanting to use fs:noenforcing but also tried just quota = fs to simplify. When I right click a folder stored in my homedir, thunderbird tells me 'the server does not support quotas' in the folder properties. What else can I do? Thanks!

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by David Jonas 06 May '08

06 May '08

Upon upgrading from 1.0.2 to 1.1rc4 I see this error for many of our users: Getting size of message UID=1 failed Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged Logging in with IMAP I would see a bunch of messages with no subject or time and blank bodies (usine horde/imp). Removing dovecot.index.log, dovecot.index.log.2, or dovecot-uidlist fixes the problem for the account (I chose dovecot.index.log). I imagine that forces a rebuild of the indexes. Removing other files in the directory didn't seem to make a difference, including dovecot.index or some arbitrary non-dovecot file. Is there a more conventional way around this problem?

[Dovecot] A previously unreported lsub/list discrepancy in 1.1rc5 and earlier
by Adam McDougall 06 May '08

06 May '08

Not sure about 1.0, I don't run it anymore :) But a few users discovered for a small issue that only affects a very small portion of my userbase where instructional correction will suffice. I guess I am reporting it in the interest of getting it out there, and I can live with it if not fixed but it might be an issue for some people. I'm running through my list of issues. Basically, if a user has a valid namespace prefix set such as mail/ (used to be required on old mail server but discouraged on new mail client setups with dovecot), lsub/list do not show public namespaces that the user has permission to via acl. If the user removes the namespace prefix, they can 'see' the public folders and subscribe. Additionally if the user subscribes to a public folder then puts mail/ back in the prefix, the folders are no longer listed. Not sure if public folders should be affected by the requested prefix in this manner, since they are not in the user's account.

[Dovecot] Replication milestone 1
by Timo Sirainen 06 May '08

06 May '08

5 milestones planned currently. I'll start with the always-on multi-master replication, because that's the most difficult one to get working correctly and efficiently. So if during its implementation I find some design problems, less code needs to be fixed. Milestone 0 will hopefully be done within a month. This includes reading and replying to the rest of the mails on this list and getting a v1.1.0 release out. :) There will most likely also be a v1.2.0 release this summer that has some new features on top of v1.1. Several companies have asked for replication within the past year. At least two are willing to contribute some money into its development this summer, but having more wouldn't hurt of course. :) Paying also guarantees (within reasonable limits) that I'll listen to what kind of a installation you're planning and make sure that the replication will work in that kind of a setup. So, below's the milestone 1 fully described with a couple of FIXMEs left. The rest of the milestones are described only briefly. 0. Prerequisites: - Change v1.2 CONDSTORE implementation to allocate modseqs differently. Currently log file sequence + offset determines the modseq. This can't work in a cluster since their log files are different. Instead add a new "UIDs [..] have modseq X" transaction log record that gets updated when needed. UID list can be 0 to update higest-modseq. To avoid adding modseq for all changes, we can be optimistic and assume that usually multiple servers aren't doing changes at the same time. So the next transaction after modseq=5 record will have modseq=6 and the following one modseq=7, etc. - Update v2.0 framework to include v1.2 changes and make it work. Base the replication code on top of v2.0. - Shared mailboxes making all users' all mailboxes available for read/write within the same (replication) process. 1. Incremental replication for existing mailboxes. IMAP, POP3 and deliver use a replication plugin, which connect to a replication process via UNIX socket (or TCP optionally for chroots). The plugin sends the SAVE, EXPUNGE and STORE changes to the replication process, which forwards them to other servers. The other servers receive the commands and store them to local filesystem. The sending and the receiving sides have quite distinct jobs, so they should probably be implemented as separate processes. They could still use the same TCP socket though, replication sending process writes to the socket and replication receiving process reads the socket. The processes still need to share some state though. Most importantly keeping track of the mailbox master servers. This is probably the most cleanly implemented by having a separate master tracking process which the sending/receiving processes talk to via UNIX socket. The rest of the data sharing is about forwarding command replies (SAVE, STORE with CONDSTORE flag) to replication sender, so it can pass them on to the originating mail process. This can be done easily using an extra pipe/socket between the processes. Examples use: - C1 = Client 1 - C2 = Client 2 - S = Replication sending process - R = Remote replication receiving process - Small letter before commands = IMAP-like command tag - * before commands = tag for a command that doesn't expect a reply 1.1. Master tracking process Master tracking process is connected to sending and receiving replication processes. LOCK: (mail process -> replication sender -> master tracker) - User name - Mailbox name Reply: - success LOCK is sent by replication plugin from mail processes when it wants to assign UIDs for new messages. Replication sender proxies this command to master tracker. If server is already the master, the command returns success immediately. Otherwise tracker looks up from its cache who the current master is and requests it using the REQUEST command. Once GIVE command is received, reply success to the mail process. FIXME: handle timeouts (and master disconnections) somehow? UNLOCK: (mail process -> replication sender -> master tracker) - User name - Mailbox name No reply. UNLOCK is sent by mail processes after they've finished assigning UIDs and sending replication SAVEs. If this was the last lock, pending TAKE requests for this mailbox are handled. GIVE: (replication receiver -> master tracker) - User name - Mailbox name No reply. Notification that this server is now the master for the specified mailbox. If there are any pending LOCK requests for this mailbox, they're replied to in here. TAKE ([mail process ->] replication receiver -> master tracker): - User name - Mailbox name - Server ID No reply. Request for giving master state for the specified server. When this mailbox contains no locks, the TAKE command is forwarded to replication sending process which passes it to the requesting server. While waiting for existing locks to be releases, handling new LOCK commands for the mailbox must be delayed to avoid lock starvation. When forwarding TAKE command, the destination server ID is cached as being the mailbox's current master. If we're not the current master for this mailbox, forward the request using REQUEST command. This also happens if there are multiple pending TAKE requests. The first one gets to become the master and the rest of them are handled as REQUEST commands. REQUEST (master tracker -> replication sender): - User name - Mailbox name - Server ID of the current assumed master - Server ID who wants to be the new master (e.g. ourself) Request master status to be moved to the specified server. If server ID isn't ours, cache it as being the mailbox's current master. If we don't have any idea who the master might be currently, use the root server ID. ROOT-SET (replication receiver -> master tracker): - Server ID This command causes all cached master states to be dropped. Any new LOCK requests are delayed. Once all mailboxes are unlocked, drop being a master from all mailboxes and send ROOT-CLEAR command to replication sender, which passes on the information that we've cleared the master states. The given server ID is set to be the new root. ROOT-CLEAR (replication receiver -> master tracker): - Server ID Given server ID has notified that it has cleared its master states. If we're not the current root, this command is forwarded to it. If we're the root and this was the last pending ROOT-CLEAR, start handling the pending REQUEST and LOCK commands. FIXME: How is initial root selection done? How is it decided who's the new one when previous one dies? 1.2. Replication sending 1.2.1. Saving (For now we ignore the possibility of saving as non-master.) When a mail process wants to give UIDs for newly saved messages, it first requests for master lock for the mailbox from the master tracker process. Once UIDs have been assigned for the new messages, the messages are sent to replication sender using SAVE commands. After the last one is sent, the master lock is dropped. Note that this lock duration should be as small as possible, so in Dovecot's code this means doing both locking and unlocking in mailbox_transaction_commit(). If multiple processes are sending SAVEs at the same time, the replication sender may receive the UIDs in wrong order. It must reorder them before forwarding the SAVEs to other servers. Since all master LOCK/UNLOCK commands pass through the replication sender, it can figure out when it has seen all the SAVEs based on them. For example: C1-C3 -> S: a LOCK [1] S -> C1-C3: a OK [Client 1 sends the first mail] C1 -> S: b SAVE uid=5 .. [SAVE uid=5 depends on dropping [1] locks (currently clients 1,2,3)] C1 -> S: * UNLOCK [1] (left 2) [Client 1 starts sending more mails in a separate transaction, lock counter is incremented because of the previous SAVE] C1 -> S: d LOCK [2] (remember lock[2].prev_uid=5) S -> C1: d OK [Client 2 sends its mail] C2 -> S: b SAVE uid=9 .. [SAVE uid=9 depends on dropping [1-2] locks (currently clients 1,2,3)] C2 -> S: * UNLOCK [1] (left 1) [Client 3 sends its mail] C3 -> S: b SAVE uid=3 .. [SAVE uid=3 depends on dropping [1] lock (currently client 3). It doesn't depend on [2] lock, because uid < lock[2].prev_uid (3 < 5)] C3 -> S: * UNLOCK [1] (left 0) [SAVEs depending on [1] locks are ordered and forwarded.] S -> R: x SAVE uid=3 .. S -> R: y SAVE uid=5 .. [Client 1 finishes its second transaction] C1 -> S: f SAVE uid=7 [SAVE uid=7 depends on dropping [2] lock (currently client 1)] C1 -> S: * UNLOCK [2] (left 0) [SAVEs depending on [2] locks are ordered and forwarded] S -> R: x SAVE uid=7 .. S -> R: y SAVE uid=9 .. The idea is that locks have a counter which is incremented if there was a SAVE command sent after the previous LOCK command. The previous SAVE's UID (prev_uid) is also stored to the lock. When the first SAVE after LOCK arrives, it's assigned a dependency on all existing locks which have uid > prev_uid. The lock counter order doesn't guarantee an ascending prev_uid order. (An actual lock counter probably isn't even needed, prev_uid should be enough as the lock ID. Lock counter simplifies the above example though.) All subsequent SAVEs from the client before the next UNLOCK will have the same dependency as the first SAVE. This is because by that time the transaction has been committed and all messages within the transaction have been given UIDs. So in fact it wouldn't really matter in which order the SAVEs are even sent to the replication sender. Although sending them in order allows an extra optimization: If only a single client is holding a lock, the SAVEs can be immediately forwarded as they're being received. After all lock dependencies have been dropped, it's guaranteed that all new SAVEs will have higher UIDs, so the SAVEs can be ordered and forwarded. A further optimization could use some kind of weak locks that are dropped after the client's first SAVE command. After the weak lock count has dropped to zero, the messages can started to be sent. For example assume two clients having the same lock counter. Both clients would be sending 10000 messages within the same transaction. Waiting for and buffering all of them would waste a lot of memory. Instead it would be possible to read the first SAVE from the first client and then block until the first SAVE is read from the second client. The SAVE with a smaller UID can be forwarded to remote servers. The next message is then read from that connection, and this is continued until all messages have been processed. A simpler solution would have been to order and forward SAVEs only when lock counter dropped to zero, but under very high load it's (at least theoretically) possible that the counter never drops to zero. In synchronous setups (recommended whenever possible) the SAVE commands use a tag (not "*"), which requests an ack reply from the remote. After replication sender has sent SAVE to a remote server, the remote server eventually replies back. This reply is forwarded from replication receiver to sender, which in turn forwards it to the mail process. After mail process has finished sending all SAVEs, it waits until it has received at least one ack for each SAVEd message. If the replication sender sent the SAVE to multiple servers, mail process may receive multiple acks for each message. It should just ignore the ones it doesn't care about. 1.2.2. Modseq updating If all mailbox modifications were done only while the server was the mailbox master, there wouldn't be any problems with modseq updates, because only one server could modify the mailbox at a time. This scales badly though, so it's preferrable to move the master only when absolutely required (for SAVEs) and handle modseqs another ways. Modseqs are incremented by each mailbox modification. All modification commands contain a modseq parameter. When applying the modification command make sure the local modseq is at least as high as the modification command's modseq. If the local modseq is higher, broadcast the new modseq to all other servers using MODSEQ command. When receiving a MODSEQ command, update the modseq only if its current value is lower than the received one. Remember that modseqs can also be updated for expunged messages. All this means that eventually everyone's modseq will be the highest assigned modseq for the change in the cluster. It doesn't matter if temporarily some clients saw lower modseqs. The worst that can happen is that some extra FLAG/MODSEQ updates are sent to the client. Although there is a problem if a client can jump from a server where it had higher modseqs to a server that hadn't yet received the incremented modseqs and performed a sync using the higher modseq. If the updated modseqs come after the sync, they're lost from the client. This could be avoided by issuing a cluster-wide sync wait before such syncing commands are run. 1.2.3. Expunging EXPUNGE commands can be replicated without waiting for anything. There are problems with messages getting expunged while COPY is being handled, but this will be resolved later when COPY is implemented. 1.2.4. Flag updates When STORE is received by a master, it checks if it has higher modseqs in messages than the modseq in STORE parameter. Then it applies all the changes and forwards the changes to other servers using possibly updated modseqs. For messages that had higher initial modseqs their current flags are sent back to the originating server to fix a potential desync. If STORE is initiated by the master, there are no flag desynchronization possibilities. The correctness of applying conflicting changes could be improved by including a "highest modseq of messages before this STORE" parameter. The applying server (master) could then find the flags from that point in time and apply changes on top of it. And finally on the top would be applied newer changes (that were already once applied). There could still be conflicting changes, but the result would be better for updates that had been delayed for a long time. Finding these flag changes and old flag values isn't simple though, so this won't be at least in initial implementation. STORE UNCHANGEDSINCE (CONDSTORE extension) is initially implemented by grabbing a master lock. If there are simultaneous STOREs in other servers, they'll temporarily have lower modseqs and different message flags. Eventually when the STOREs reach the master, they will be applied on top of the CONDSTORE modification. So even if normal STOREs were sent slightly earlier than CONDSTORE, they'd eventually be applied on top of the CONDSTORE change. This makes the STORE UNCHANGEDSINCE work correctly (even if with a slight delay), and our multi-master replication should be fully compatible with the CONDSTORE spec. 1.3. Replication receiving Replication receives 3 different types of data from remote sender: 1. Replies to commands this server's replication sender sent 2. Message texts (as part of SAVE) 3. Metadata updates (SAVEs, STORE, EXPUNGE, etc.) Command replies are handled by directly forwarding them to the replication sender process via a pipe/socket. 1.3.1. Receiving SAVEs The message text part of the SAVE is stored in a file. The file format depends on the server's configured default data format. For now we consider only maildir format where the data is written as-is to the file. This file is later hard linked to the destination maildir directory. If multiple partitions are used, the file should be written to the correct partition. The initial code could write the file to the destination mailbox's tmp/ directory to make sure the partition is correct. There may be some permission problems with this approach though, a separate replication drop directory would be nicer. The rest of the SAVE is processed similarly to other metadata updates. The path to the written file is added as new metadata to the SAVE command. 1.3.2. Metadata updates The primary replication receiver process's job is to read data from the network as fast as possible. Processing the actual updates can take a while, so the work is distributed to multiple worker processes. As discussed above, the primary replication receiver process still writes message texts to files. The workers could do this as well, but it would mean that the text needs to be sent via IPC to the workers, which adds extra overhead. If the message writing really becomes the bottleneck, this change could be done. The replication receiver tries to pass the same user's updates to the same workers so they can benefit from keeping mailboxes open longer. Each worker could be limited to e.g. 100 open mailboxes. The worker handles the SAVE/EXPUNGE/STORE commands using the normal mailbox handling functions. After the changes were successfully committed, commands that had tags are replied as having succeeded. If a change failed, a failure reply is sent instead for it. Replication receiver passes this reply to the replication sender (not to be confused by remote command replies which are also forwarded), which in turn passes it to the originating server. ------ 2. Mailbox synchronization for existing mailboxes. - As described in the replication protocol. - IMAP UID conflict resolution. 3. Mailbox list synchronization. - Track creates, deletes, renames. - Add unique global mailbox ID which is preserved across renames and allows replication to perform renaming (and symlinking?) 4. More features 4.1. Global UIDs - Save GUIDs to messages (dbox: metadata, maildir: dovecot-uidlist) - Tracking GUIDs globally - Implement COPY command - Implement SAVEs sending only global UIDs and FETCHing unknown ones 4.2. Support for untrusted user-run replication processes - Make SAVE and work without being a master - Make CONDSTORE's STORE UNCHANGEDSINCE work without being a master 4.3. Transactions - Wrap changes into transactions just like they're in the originating Dovecot's transaction (e.g. TX-BEGIN, TX-END commands) - On receiving side a transaction is handled in a single Dovecot transaction by a single worker. 4.4. Cluster-wide sync - Broadcast a ping packet and wait for a reply from all servers on the cluster. This ensures that all changes before the ping packet was sent have been received. - Then ping replication receiver process and have it ping worker processes to wait until all received changes have been committed. - CHECK command could do it. - CONDSTORE/QRESYNC commands that take modseq parameters could maybe do it? Or would it be too slow? It would at least increase reliability. We could probably also figure out some rules when the sync is needed and when not. 5. dbox support - Message text can't just be written to a file and renamed. At minimum some dbox metadata needs to be written to it. - Files can't be shared between mailboxes by hard linking like they can be with maildir

[Dovecot] Timeout when using icedove's searching on a large amount of email.
by guillaume.yziquel＠free.fr 05 May '08

05 May '08

Hello list. I'm using dovecot as a local server, where I'm the only user (or so), and I appreciate using icedove searching functionality to roam through the whole inbox in search of some specific string in the body of my emails. Unfortunately, recently, such a search has become impossible, since the search takes too much time, and the connection times out. I've looked throughout the .conf file and the documentation, but I haven't found where I could increase the delay until timeout. If someone knew the right option in the .conf file, it would be really great... Guillaume Yziquel.

Hello I've noticed a little strange behaviour of that option. For example with following settings: system user: admin, with its home directory as /home/admin dovecot options: as reported by dovecot -n (in attachment) dovecot will try to chroot into /home/home/admin with the following message in logs, in my case: Fatal: chdir(/home/home/admin) failed with uid 1999: No such file or directory The same happens if I use per-user chroot= option in userdb, f.e. in passwd-file I've noticed it's just now, as I've always used explicit chroot dirs specified through passwd-file with /./ (which works perfectly fine, except harmless double slashes in logs), and didn't bother with single system user (I made some chroot/lock related bugreports in distant 1.0rcXX past).

Hi, I was wondering - are there any plans on switching the sieve plug-in to use libsieve (http://libsieve.sourceforge.net/)? The rationale of using this library is simple - cmusieve codebase seems stagnant and libsieve promises to implement some new sieve rfc drafts. -- matik

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc5.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc5.tar.gz.sig I've finally gone through all my unread mails and fixed most of the reported bugs. There are only a couple ones left that I can't reproduce. Please report if you still have any problems with rc5, even if you already have reported the same bug before. v1.1.rc6 will hopefully be the last RC before v1.1.0. + Support cross-realm Kerberos 5 authentication. Based on patch by Zachary Kotlarek. + Added dict_db_config setting to point to a Berkeley DB config file. + If mail_chroot ends with "/.", remove chroot prefix from home directory. - Fixed several bugs and memory leaks in ACL plugin. LIST and LSUB may have listed mailboxes where user had no 'l' access. STORE could have been used to update any flags without appropriate access. - mbox: Valid-looking From_-lines in message bodies caused the message to be split to two messages (broken since v1.0). - Plugin initialization hooks were called in wrong order, possibly causing problems when multiple plugins were used at the same time. - Expire plugin was broken - LIST-EXTENDED options were ignored. - LDAP: Static attribute names weren't working correctly - deliver: mail_uid and mail_gid settings weren't used. - pop3 + maildir++ quota: maildirsize file wasn't created if it didn't exist already. - dnotify: Waiting for dotlock to be deleted used 100% CPU
