[Dovecot] v1.2: can't access other users shared INBOX
by Sascha Wilde 06 Apr '09

06 Apr '09

Hi *, when a user A shares his INBOX with another user B, the user B can't access its content: User A: g getacl INBOX * ACL INBOX A(a)example.com lrswipkxtecda B(a)example.com lrswipkxtecd g OK Completed User B: l list "" "*" * LIST (\Noselect \HasChildren) "/" "user" * LIST (\Noselect \HasChildren) "/" "user/A(a)example.com" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/Gesendet" * LIST (\HasChildren) "/" "user/A(a)example.com/foobar" * LIST (\HasNoChildren) "/" "user/A(a)example.com/INBOX" l OK List completed. s1 select "user/A(a)example.com" s1 NO [CANNOT] Invalid mailbox name s2 select "user/A(a)example.com/INBOX" s2 NO [NONEXISTENT] Mailbox doesn't exist: INBOX Actually there are two bugs to observe here: 1) "user/A(a)example.com" really should be accessible to user B. Why is it listed with "\Noselect"? 2) "user/A(a)example.com/INBOX" does not exist, so the error message is correct, but why does it appear in the listing in the first place? cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Implementation of editheaders in dovecot
by Konstantin Lepa 06 Apr '09

06 Apr '09

Hello. I wrote the hook function for deliver. I want to add support of editheaders in the plug-in for dovecot. For this purpose I wrote the function rarules_get_stream. Remover of headrs works properly, but adding does not work. I took Timo Sirainen's advice from http://markmail.org/message/skb6arnll5gaopdr . Do I use a correct way of creation of a message? I give backtrace and a part of my code.

[Dovecot] is it possible to recover files from a dovecot.inboxe.cache file?

06 Apr '09

I found this file in the mail boz and noticed it had 20 emails in it (though you can only read really the header the body is cryptic cause it is a bin file?) Just not sure if I can and how to use this to restore the lost emails in that inbox. Thanks

[Dovecot] Segfault in Sieve 1.2
by Bernhard Schmidt 06 Apr '09

06 Apr '09

Hello, two days ago I've upgraded to 1.2rc2 and the new sieve implementation (version 0.1.4). Today I got the first mail that got stuck in the postfix queue because deliver was dying with a segfault. The mail is spam, thus I don't have any issues sharing it: http://users.birkenwald.de/~berni/temp/deliver-segfault.mail It happens with this small sieve script (my normal one is larger, but this is the part that triggers the segfault): http://users.birkenwald.de/~berni/temp/deliver-segfault.sieve Note that I've been running this script unaltered for months, first with Dovecot 1.1 and CMUSieve and now with various versions of Dovecot 1.2 and the new sieve implementation for about three weeks, this is the first mail that got stuck. I got a coredump, but without debugging symbols it doesn't tell that much. If you can't reproduce it I'll compile it with debugging symbols and try again. (gdb) bt full #0 0x00007fa0f87ecbd7 in strstr () from /lib/libc.so.6 No symbol table info available. #1 0x00007fa0f8341933 in ??

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc2.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc2.tar.gz.sig Somehow I forgot to check that "make distcheck" finished successfully in rc1, so rc1 didn't actually even fully compile. No other changes since rc1 than the compile fix.

[Dovecot] THREAD X-REFERENCES2 index bug?
by Nathan Kinkade 04 Apr '09

04 Apr '09

Hi all, $ sudo dovecot --version 1.2.beta3 I just started using Dovecot a few weeks ago, and my client is also using the X-REFERENCES2 thread algorithm. The client is misbehaving when trying to list messages in my INBOX, but only when a threaded message exists. I have tracked it down to the thread index that Dovecot is returning, but the problem is only extant when using the X-REFERENCES2 thread algorithm. Here is a snippet of transcript from imap client that comes with Dovecot: $ export MAIL=maildir:~/Maildir:INBOX=~/Maildir/INBOX $ /usr/lib/dovecot/imap <snip> 1 SELECT "INBOX" <snip> 2 THREAD X-REFERENCES2 UTF-8 ALL * THREAD (0)(2)(1 3)(4) 2 OK Thread completed. There are, in fact, only 4 messages in my INBOX, and the reference to (0) seems spurious. When I do the same test, but passing REFERENCES instead of X-REFERENCES2 Dovecot returns an index which I believe to be correct: <snip> 2 THREAD REFERENCES UTF-8 ALL * THREAD (1 3)(2)(4) 2 OK Thread completed. <snip> Is this the normal and expected behavior of X-REFERENCES2 that the client just needs to take into account, or is the reference to thread index (0) an error? Thanks! Nathan

Hi By playing around with imap acl I managed to get another crash. Setup is the same as in my last crash report ("1.2 beta4, crash with ACL"), except updated from beta4 to rc2 and added the slash to the prefix, as suggested by Timo: prefix: shared/%%d/%%n/ What I did: logged in as sales 2 setacl INBOX oli@<domain>.ch -lrs Connection closed by foreign host.

[Dovecot] v1.2.rc1 released
by Timo Sirainen 03 Apr '09

03 Apr '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz.sig I think it's time to get v1.2.0 out soon. Shared mailbox code is beginning to look like it's working and other features should work fine also. I don't really see any reasons to delay it, so please start testing and let's get the last bugs found and fixed quickly. I'm also going to start v1.3 branch soon with configuration rewrite and multi-dbox support. Changes since beta4: * Renamed THREAD X-REFERENCES2 to THREAD REFS (from INTHREAD draft) + When a process is killed, show the signal code and the sending process's pid and uid. + quota-fs: Added support for NFS group quota. - Several fixes to shared mailboxes and ACLs - Removed umask setting. We're nowadays creating practically all files with proper umasks. - acl: Dropped default ACL cache timeout from 5 minutes to 30 seconds. - fts-solr fixes - virtual mailbox fixes - Write to main index file less often.

[Dovecot] Missing mail_max_userip_connections setting
by Thomas M Goerger 03 Apr '09

03 Apr '09

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present?

[Dovecot] Maildir files with mtime in the future
by Holger Weiss 03 Apr '09

03 Apr '09

If Maildir storage is used, the mtime of a given Maildir file is set to the message's INTERNALDATE. Now, when a client APPENDs a message to an IMAP mailbox, the client may optionally specify the INTERNALDATE: | If a date-time is specified, the internal date SHOULD be set in the | resulting message; otherwise, the internal date of the resulting | message is set to the current date and time by default. [ ftp://ftp.fu-berlin.de/doc/rfc/rfc3501.txt (6.3.11. APPEND Command) ] However, if the client does so, Dovecot will set the mtime of the Maildir file in question to the date specified by the client even if it's in the future. Since files with an mtime in the future can cause all sorts of trouble (e.g., they might get backed up repeatedly by incremental backups), it would be nice if Dovecot would (optionally?) use the current time if the client specifies a time in the future. For example, we use the following patch: ---------- 8< ---------------------------------------- 8< ---------- diff --git a/src/imap/cmd-append.c b/src/imap/cmd-append.c index 0b22fd5..b7e42b9 100644 --- a/src/imap/cmd-append.c +++ b/src/imap/cmd-append.c @@ -319,6 +319,12 @@ static bool cmd_append_continue_parsing(struct client_command_context *cmd) return cmd_append_cancel(ctx, nonsync); } + if (internal_date != (time_t)-1 && internal_date > time(NULL)) { + /* the client specified a time in the future, set it to now. */ + internal_date = (time_t)-1; + timezone_offset = 0; + } + if (ctx->msg_size == 0) { /* no message data, abort */ client_send_tagline(cmd, "NO Can't save a zero byte message."); ---------- 8< ---------------------------------------- 8< ---------- Holger

[Dovecot] v 1.1.13 / GSSAPI / Timeout waiting for handshake from auth server
by Jahnke-Zumbusch, Dirk 03 Apr '09

03 Apr '09

Dear all, I am trying to setup Dovecot with GSSAPI support. For testing purposes gssapi is the only method allowed for login. As I cannot login to my mailbox, I'vo got two questions about the following log entries: dovecot: Info: auth-worker(default): passwd-file /dovecot/store/db/test-userdb: Read 3 users dovecot: Info: auth(default): new auth connection: pid=3915 dovecot: Info: auth(default): client in: AUTH 1 GSSAPI service=imap lip=131.169.*.* rip=131.169.*.* lport=143 rport=35779 dovecot: Info: auth(default): gssapi(?,131.169.40.218): Obtaining credentials for imap(a)my.host.name dovecot: Error: imap-login: Timeout waiting for handshake from auth server. my pid=3918, input bytes=0 1. I am puzzled about the credentials "imap(a)my.host.name" being obtained; shouldn't this be something like "imap/my.host.name(a)MY.REALM" ? 2. what does "Timeout waiting for handshake from auth server." mean? Who is trying to handshake with whom? Any ideas?

[Dovecot] Time moved backwards errors
by Bloke 03 Apr '09

03 Apr '09

Hello, I am experiencing a number of 'Time moved backwards errors' such as: Mar 27 11:38:20 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 729 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 27 15:20:10 host-78-129-239-60 dovecot: Time just moved backwards by 4214 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 29 11:08:59 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 4341 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards on my Centos 5.2 openvz - based VPS I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem. Reading the TimeMovedBackwards article on the Dovecot wiki, and the kernel mailing list thread referred to on it, it would seem quite apparent that this is caused by a failure of the gettimeofday() function to reliably return the correct value. If anyone has any advice as to how I could proceed to fix this (I currently have a watch on the Dovecot service which restarts it after any failures) or how I should best phrase this to get it resolved 'upstream' by the VPS provider, I would be very grateful. Thank you, Patrick Vale

[Dovecot] dbox benchmarks
by Timo Sirainen 03 Apr '09

03 Apr '09

http://hg.dovecot.org/dovecot-dbox-redesign/ Looks like multi-dbox scales pretty nicely. Even after 100k messages the peak saved msgs/sec is the same as the initial saved msgs/sec, even if the average slows down somewhat. I tested this by first deleting mailbox, then running "imaptest" for a second to get saving to start writing several fields to dovecot.index.cache file. Then ran imaptest for 60 seconds that did nothing but save messages using IMAP APPEND commands. The summary is that multi-dbox is almost 10x as fast as maildir when fsync is disabled and 2,5 faster with fsyncing: fsync_disable=yes: multi-dbox : ~1700 -> ~1500 msgs/sec, 90842 msgs/60 sec single-dbox: ~1700 -> ~1400 msgs/sec, 86149 msgs/60 sec maildir : ~330 -> ~110 msgs/sec, 9789 msgs/60 sec fsync_disable=no: multi-dbox : ~220 -> ~170 msgs/sec, 10113 msgs/60 sec maildir : ~100 -> ~70 msgs/sec, 4123 msgs/60 sec Also I just noticed that saving messages with two clients gets a peak of 2200 msgs/sec, most likely because two CPU cores can be used then. Hmm. I guess if there were no locking it should have reached 3400 msgs/sec, but it's better than no performance increase.

[Dovecot] An issue of I login my mail server from webmail client

Dear all: I have a really strange issue, that is when I login my mail server from webmail client (I used SquirrelMail, by the way, I have modified squirrelmail's timeout value, that means not since squirrelmail timeout), I will got timeout issue when I login about 5PM ~ 10PM everyday (it works fine on other time, I also check my cron, that looks no problem), and during this time, I also cannot connect my 993 port with openssl like this: openssl s_client -connect myDomainName:993 But when I use mail client (such as outlook) to access dovecot, that works fine, and during 5PM ~ 10PM, my web site also works fine, and once I restart computer if I can not login during 5PM ~ 10PM from webmail client. that will work fine. can you try to help me? below is my configure of dovecot. *dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/run/dovecot/maillog info_log_path: /var/run/dovecot/maillog protocols: imaps ssl_parameters_regenerate: 0 verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: convert_mail: mbox:~/Mail:INBOX=/var/mail/%u* -- Best Regards Alan Zheng

[Dovecot] Dovecot ACLs

03 Apr '09

Running Dovecot 1.1.8 using Virtual users, multiple domains. My file structure is /var/spool/mail/<domain>/<user>/Maildir/ (cur, new,tmp,.Spam) What I'd like to do is add an ACL such that all users can read/delete/move mail that's in the spam folder, but not delete it. Am I going to have to create an entry for every single user, or is there a way to do it once, for all .Spam folders? I've read through http://wiki.dovecot.org/ACL and can't quite get this as the last step. Thanks rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Fatal: imap-login: io_loop_handle_add: epoll_ctl(1, 4): Operation not permitted

Hello, I'am following the beginning tutorial on the Wiki, but actually, I can't even start the server correctly so far. The imap-login child dies immediately. What I can guess from the log is that it tries some unpermietted operations on some files but I can't find out which files are concerned. Google is not my friend at all either on this matter. How can I know which files are concerned ?

[Dovecot] Squat memory usage
by Ryan 02 Apr '09

02 Apr '09

I've been reading about using Squat with Dovecot on large mailboxes. I was wondering if some of the memory usage during searching and indexing could be reduced by using a berkeley db? I've used this in the past for something similar and in BTREE mode it was very fast for millions of keys. I havent had time to look at how squat is implemented, but I thought I'd throw it out there... -Ryan

[Dovecot] v1.2.beta2: Fatal: io_loop_handle_add: epoll_ctl(1, 10): Bad file descriptor
by Pascal Volk 02 Apr '09

02 Apr '09

Hi Timo, I'm playing with Dovecot v1.2.beta2 currently. When the dict process was started via deliver(?) and Dovecot is killed (kill $PID_OF_DOVECOT) after delivering only one message, it logs: Fatal: io_loop_handle_add: epoll_ctl(1, 10): Bad file descriptor If the dict process was not started or deliver has delivered more than one message, the error doesn't occur. I'm not using SELinux or AppArmor or something similar. # 1.2.beta2: /usr/local/dovecot12/etc/dovecot.conf # OS: Linux 2.6.26-1-amd64 x86_64 Debian squeeze/sid log_path: /usr/local/dovecot12/var/log/dovecot.log protocols: imap listen: 10.11.12.13:10143 ssl: no disable_plaintext_auth: no login_dir: /usr/local/dovecot12/var/run/dovecot/login login_executable: /usr/local/dovecot12/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 70000 first_valid_gid: 70000 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_plugins: quota imap_quota auth default: mechanisms: digest-md5 cram-md5 login plain user: nobody verbose: yes debug: yes passdb: driver: sql args: /usr/local/dovecot12/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/dovecot12/etc/dovecot-sql.conf socket: type: listen master: path: /usr/local/dovecot12/var/run/dovecot/auth-master mode: 384 plugin: quota: dict:user::noenforcing:proxy::quotadict quota_rule: *:storage=10M:messages=11 quota_rule2: Trash:storage=50%% mail_debug: yes dict: quotadict: pgsql:/usr/local/dovecot12/etc/dovecot-dict-quota.conf Regards, Pascal -- The trapper recommends today: cafefeed.0907505(a)localdomain.org

[Dovecot] quota-fs: get nfs GROUP quota (patch)
by fandorin＠rol.ru 02 Apr '09

02 Apr '09

Hi all. Unfortunately, the existing quota-fs does not know how to get GROUP quota with NFS storage. But there is a tool for Linux quota-tools (http://slackware.rol.ru/slackware/slackware-12.2/source/a/quota/) This patch is made on the basis quota-tools. The patch was successful alpha testing.

[Dovecot] File and group permissions for incoming mails
by Sascha Scandella 02 Apr '09

02 Apr '09

Hello I am using Dovecot 1.1.1 together with Postfix (and for some users Procmail for Spam Filtering). Until now I didn't have to use shared mailboxes. Now I want to use simple simlinking to grant other users of the same group access to my mails. The problem is that new incoming mails have always file permissions set to 0600. I have also a file called dovecot-shared (0660) in the Maildir folder. No success. Why doesn't this work? I also tried to use UMASK in the procmailrc. No success. Any help is appreciated! Best regards Sascha

[Dovecot] dbox - how to awaken the monster
by Odhiambo Washington 02 Apr '09

02 Apr '09

Hello people, Since the invention of this storage called dbox, I have never quite gotten round to understanding it, nor getting to use it. It seems so strange to me and I must ask a few stupid questions about it. I use the MTA to deliver mail to Maildir, either in ~/Maildir or /some/path/%d/%n/Maildir. It has always beat me how dbox comes into play under such circumstances. From the wiki, I see the following: "dbox supports a quick migration from Maildir format" - now this leaves me hanging. How? Suppose I migrate from Maildir to dbox, what changes do I make to the MTA to understand that I use dbox? Ok, I use Exim as my MTA. I hope someone can explain to me what I need to do to Exim and what to do th Dovecot so that I can test this dbox thing. And suppose I want to transfer userA's mail to UserB, what do I do? With Maildir, I can simply do something like mv ~A/Maildir ~B/Maildir chown -R B ~b/Maildir Suppose I am using dbox, howdy? Thank you in advance. I know those sound dumb, but I simply haven't understood dbox. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "The only time a woman really succeeds in changing a man is when he is a baby." - Natalie Wood

[Dovecot] Dovecot in OSCON 2009?
by Timo Sirainen 02 Apr '09

02 Apr '09

Hi, I'm thinking about attending OSCON 2009 with some other people from Mailtrust and having some kind of an informal Dovecot meeting nearby. We could for example talk about what Dovecot would need to work better in your system, like missing features or if some things are annoyingly difficult etc, or just general talking and socializing. If you're interested in joining, send me a mail (privately, unless you have something else to say besides "yes").

[Dovecot] Slightly OT : Maildir format (silly) questions
by Thomas Hummel 02 Apr '09

02 Apr '09

Hello, I was asking what was the motivation for not having the envelope From in the Maildir format, as defined in the qmail spec : "The message is delivered without an extra UUCP- style From_ line, without any >From quoting, and without an extra blank line at the end." which may sound silly since we lose an important piece of information. Same question about the motivation in Courrier (Maildir++) for emulating a hierarchy for subfolders (like in .folder.subfolder.subsubfolder) instead of (note : I know about layout=FS, I'm not talking about that) implementing a real filesystem hierarchy. I understand dovecot kept those for compatibility reasons but I'd like to know what was the authors of thoses specs thinking when deciding this.

[Dovecot] Informations in LDAP and Database
by Etienne MAYNIER 02 Apr '09

02 Apr '09

Hi everybody, I'm installing an application using LDAP and I want dovecot to use LDAP too. The problem is that they don't use the same schema (especially because we want per-user quotas). I think the best solution is to have the authentication by LDAP and others datas (like quotas) in a database. Is it possible with dovecot ? and How ? Thanks Etienne

Hi, I'm testing migration from courier to courier-0.57.0 to dovecot-imap-1.1.12 on a debian/sid box. When running the migration script, non of the active users' "courierimapsubscribed" and "courierimapuiddb" files seem to be detected: ZENON:~# ./courier-dovecot-migrate.pl --to-dovecot --recursive /home Testing conversion to Dovecot format Finding maildirs under /home /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/CB: No imap/pop3 uidlist files /home/XXXX/Maildir/subscriptions already exists, not overwritten /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Mail: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files Total: 0 mailboxes / 0 users 0 mailboxes / 0 users 0 errors No actual conversion done, use --convert parameter (the /home/XXXX users are old, non-active users) However when trying the courier-dovecot-migrate-1.0.pl I get plenty of mailbox matches, but since I am installing 1.1.12 it is useless to me.

[Dovecot] about quota in dovecot
by guojinpeng(郭晋鹏) 01 Apr '09

01 Apr '09

Hi, I’m currently try to use the dovecot quota plugin. I use the maildir plugin ,and use mysql as to get the quota rule.

[Dovecot] ampersand in local-part

I have a new email server (postfix/dovecot/mysql) with accounts migrated from another server (different platform) and email addresses with ampersands like "r&d(a)domain.com" that worked on my old email server are not working now.

[Dovecot] dbox with non-dovecot LDA
by Justin Krejci 01 Apr '09

01 Apr '09

Aside from the code is there any documentation on using dbox with a non-Dovecot LDA? We have our own MTA and currently use Dovecot with Maildir only for message retrieval and just have our MTA write the message files to our own directory structure (Dovecot per user mailbox locations stored in mysql) but I am interested in looking at moving to dbox if it is better for performance and other things like static filenames. One thing we'd like to do is not use the Dovecot LDA so as to control the entire inbound email delivery process all the way to verifying the actual message is 100% written to disk. Certainly we can use the Dovecot LDA if it came to it but we'd like to retain control over this entire process if possible.

[Dovecot] Virtual user folder configuration
by Daniel L. Miller 31 Mar '09

31 Mar '09

Since I'm going to make a change to my folder structure, what would be recommended so I can avoid the need in the future? All my mail users are virtual - they have no existence in /etc/passwd, nor do they have folders under /home. At this time, all mail is being delivered to maildir:/var/mail/%d/%n - and the home is the same (which is becoming more of a problem). As I see it, I have the choices of: 1. Place mail underneath home, as in /var/mail/%d/%n/mailbox Probably the simplest, but adds a level to the folder hierarchy. Does that matter in any way? 2. Place home underneath mail, as in /var/mail/%d/%n/home (unless THAT poses a problem as well, with a non-mail folder visible to the mail system) Leaves mail alone - but means the home folder is visible from within the mail system. 3. Relocate home totally outside mail, as in /var/mail/home/%d/%n Would provide isolation - but more difficulty in administration, particularly adding/deleting users. Any suggestions? -- Daniel

[Dovecot] CMUSieve with virtual users
by Guillaume HILT 31 Mar '09

31 Mar '09

Hi, I'm using dovecot 1.1.7 on Gentoo with Postfix and PostfixAdmin to manage my virtual users. I'm trying to use sieve (which has been compiled with Dovecot) but it doesn't work. I added cmusieve in the lda protocol : mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/lda My maildir scheme is : /home/vmail/%d/%n/.maildir The sieve file is in /home/vmail/%d/%n/.dovecot.sieve (i'm using the sieve variable in the plugin section). I also tried in /home/vmail/%d/%n/.maildir/.dovecot.sieve. Then I tried in /var/sieve-scripts/%u.sieve. None of these solutions worked :x I enabled all the debug options in dovecot, and i can't see anything about sieve in my logs. I'm using the same configuration without virtual users on another server and it's working fine. I'm out of ideas. Could someone has managed to use sieve scripts with virtual users ? Thanks :) Guillaume

[Dovecot] Sieve Rule for Folders
by Gerhard Wiesinger 31 Mar '09

31 Mar '09

Hello! Is it possible with sieve to do the following: When a new message is added to a folder (e.g. dovecot folder and not INBOX) then an action like forwarding it per E-Mail should be triggered. Is this possible? If yes, how does the sieve script look like? If possible, can a shell script also be triggered as action? Thanx. Ciao, Gerhard -- http://www.wiesinger.com/

[Dovecot] Empty To: Header and message_address_parse
by Wolfgang.Friebel＠desy.de 31 Mar '09

31 Mar '09

Using dovecot 1.2beta (but earlier versions should behave similarly) we have a problem in conjunction with empty To: headers and the RT request tracker. RT sends mail out using Bcc: and no To: header at all. To make some mailers happy one can configure to send a dummy To: header, which we do. Our To header looks like: To: "AdminCc of rt Ticket #123456":; The message_address_parse function called with the TRUE flag (triggers add_fixed_address) in dovecot changes that to To: AdminCc of rt Ticket #123456: MISSING_MAILBOX@MISSING_DOMAIN ; and then at least alpine does use that invalid address as Cc: address when replying. If the mail is stored in a local folder, i.e. does not get fetched via IMAP then the To: line is displayed as is and a reply does not result in an errorneous Cc: This behaviour is at least inconsistent from a user point of view. Is there some advice other than change the RT mail header generation? (other mailers seem to copy the To: line unaltered which results in an invalid address as well, therefore I admit that the real problem is with RT) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Convert from maildir to dbox
by Daniel L. Miller 31 Mar '09

31 Mar '09

Ok...I made the leap. Compiled a copy of 1.2b4 (very pleasant compile BTW - almost no warnings, nice code Timo!)...tweaked a config...had a few false starts... 1.2b4 seems to working quite nicely. Now...for my next magical trick... I would like to migrate from maildir to dbox. I've tried using the convert plugin, but it kept failing during the conversion. I should mention my paths: home (old & new) = /var/mail/%d/%n old mail = maildir:/var/mail/%d/%n new mail = dbox:/var/mail/%d/%n/dbox Note that "home" was defined as the same path as "mail" in my old config - I'm looking to fix that as well during the migration. I found entries in my mail log after the convert execution similar to: Mar 30 19:00:52 bubba dovecot: IMAP(sfox(a)amfes.com): rename(/var/mail/amfes.com/sfox/.dovecot.convert.lock/cur, /var/mail/amfes.com/sfox/dbox/mailboxes/dovecot/convert/lock/dbox-Mails) failed: Not a directory Mar 30 19:01:41 bubba dovecot: IMAP(sfox(a)amfes.com): Mailbox conversion failed for mailbox dovecot.convert.lock Now that I'm staring at that line...I'm wondering if that "home=mail" configuration is part of the problem. I currently have about a dozen users on this box - but with very large mailboxes (I still have archived mailing lists in mine!). If there's a few manual steps I need to perform to "condition" this setup prior to conversion please advise. Should I manually shift the mailboxes into a "/var/mail/%d/%n/maildir" folder? -- Daniel

[Dovecot] MAILBOXDIR question
by Stewart Dean 31 Mar '09

31 Mar '09

I'm unclear about where and how this is to be used. I gather it is to be a new standard, but I didn't seem to find anything about it in the Dovecot Wiki Mail Location page. There are some words about it in the 1.1.12/3 release notes, but perhaps I'm thick, but they're meta-ambiguous to me. Is it meant to be used like this: mail_location = mbox:MAILBOXDIR=~/mail:INBOX=/var/mail/%u instead of the current mail_location = mbox:~/mail:INBOX=/var/mail/%u ??? Sorry to be so dense. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] Panic: Trying to allocate 2147483648 bytes
by David Halik 30 Mar '09

30 Mar '09

Hi all, I recently upgraded from courier to dovecot 1.1.12 on a Solaris 9 system with about 100 users. We have been testing dovecot for sometime in a mixed Linux/Solaris environment and are aware of the index endianess issue with multiple archs. To solve this, we run with INDEX=MEMORY (as seen in the docs) so that only Linux clients have anything to do with the indexes. We generally have much more of them anyways. So far everything is working smoothly, but when someone does a search through directory with a large number of emails, dovecot dies and prints the following message: [ID 107833 mail.crit] Panic: Trying to allocate 2147483648 bytes I googled around and saw this same issue elsewhere, with NFS indexes usually being the problem. However, we have indexes turned off, so I don't understand why the same problem is still happening. Just to be sure, I ran with: mmap_disable = yes dotlock_use_excl = no mail_nfs_storage = yes But there has been no change, I can still reproduce it at will. Setting mail_nfs_index = yes caused my connections to stop working, so that didn't help either. Besides, I wouldn't think that would be the answer considering we set INDEX=MEMORY. This thread also seems to be related, but we're definitely running with this code in 1.1.12, yet it still happens: http://dovecot.org/list/dovecot/2008-September/033615.html I grabbed a backtrace if it is helpful: http://pastebin.com/f5f3d282c Also, here is dovecot -n: # 1.1.12: /usr/local/etc/dovecot.conf # OS: SunOS 5.9 sun4u protocols: imap imaps pop3 pop3s ssl_cert_file: /usr/local/ssl/certs/nbcs.key+crt.pem ssl_key_file: /usr/local/ssl/certs/nbcs.key+crt.pem 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_location: maildir:~/Maildir:INDEX=MEMORY mmap_disable: yes mail_nfs_storage: yes 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota pop3_quota 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): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: * userdb: driver: passwd plugin: quota: fs Any help would be appreciated!

[Dovecot] Upgrade from 1.0 to 1.1, plus migration from Maildir to dbox
by Daniel L. Miller 30 Mar '09

30 Mar '09

Ok - I gave up on trying to get CIFS to work - there's obviously stuff going on I don't understand. So - instead of trying to get a virtual server to work, I next tried a chroot. That worked...but imapsync error'ed out trying to handle one of my large mailboxes. I was trying to setup a "new" server, migrate all my mail over, verify everything worked - maybe even leave the virtual server operating for a while. But the fates are consipiring against me. So - time to make the leap. I want to upgrade a live version 1.0 server to version 1.1 (from Ubuntu repositories, using version 1.0.10 to 1.1.4). What special steps do I need to take to have this go smoothly? At least I have some semi-tested configs for 1.1 that I can use. Do I just stop the server, upgrade, upgrade the configs, start - and pray? Or is there another step? Also, my legacy installation was using maildir - I'd like to try shifting to dbox. Do I just need to change the prefix on mail_location and the conversion will magically happen? -- Daniel

[Dovecot] dovecot: auth(default): ldap(...): Authenticated user not found
by Stas SUSHKOV 29 Mar '09

29 Mar '09

Hi, I'm trying to set up dovecot together with postfix and experience some problems. Here's in details what I have and what I want to get. I have a ldap server on localhost, a working setup of dovecot to serve sasl, imap using ldap, a working setup of Postfix for (s)smtp (I can authenticate which uses dovecot's sasl). What i wan't to get is a completely working email server for ldap users with their email forwardings (so far they have only 1 forwarding). The porblem I stuck on is the following: when sending mail through (s)smtp, after passing authentication, I get my email dropped. And I see this in logs: http://ciorne.softwareliber.ro/index.php/view/raw/aaf3eb42 ***Authenticated user not found!!!*** My dovecot conf is this: http://ciorne.softwareliber.ro/index.php/view/raw/f8696531 And my dovecot-ldap is this: http://ciorne.softwareliber.ro/index.php/view/raw/698dc851 (I'm using prefetch) Can somebody point me where's my problem. *Any* advices are welcomed!!! Thank you in advance. P.S.: Environment is a vanilla installation of Ubuntu 8.04.02 with latest updates. -- () Campania Panglicii în ASCII /\ http://stas.nerd.ro/ascii/

[Dovecot] sendmail with dovecot sasl
by Mario Pavlov 28 Mar '09

28 Mar '09

Hi, I was wondering if I can make sendmail use dovecot's SASL implementation...maybe I should somehow compile it against dovecot's SASL ? My idea is to make sendmail and dovecot authenticate against one central user/password repository. Is this possible ? thank you. P.S. I want to use virtual users

Hi, Is there a way for dovecot to use a pool of sql (mysql) servers and load balance queries between these? Also fallback to next available sql server if connection to previous one fails. Can dovecot do such things currently? (If not this is feature request). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 27 Mar '09

27 Mar '09

Hi Timo, Not sure if you saw this yet, or if you're still working on a response. Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] outlook problem if TLS mailsettings are off
by Georg Käfer 27 Mar '09

27 Mar '09

Dear List, I dont know if its a config problem or its an outlook 2007 issue. Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled) can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly. Other ssl/tls settings: ssl_disable = no login_process_per_connection = yes using or not using following makes no difference... imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh I'm sad - but I cant force SSL/TLS for my users - so I cant "solve" this by using "disable_plaintext_auth = yes" Is there any way out of the dark? my data: gentoo linux dovecot 1.1.7 postfix 2.5.5 postfixadmin-2.2.1.1 mysql 5.0.70-r1 php 5.2.8-pl12 dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-gentoo-r3 i686 Gentoo Base System release 1.12.11.1 ext3 protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/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 mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 30 first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 12 last_valid_gid: 12 mail_privileged_group: mail mail_uid: mail mail_gid: mail mail_location: maildir:/var/mail/%d/%n/Maildir/:INDEX=/var/mail/%d/%n/indexes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.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: mail group: mail regards, Georg

[Dovecot] very slow pop3 downloads

Hi all, I have a dovecot installation which very suddenly decided to slow to a crawl yesterday after being totally fine for months.

[Dovecot] Preventing IMAP folder deletion?
by dovecot＠corwyn.net 27 Mar '09

27 Mar '09

Hi! I'm running postfix with dovecot using mysql for user accounts, with Outlook being used as the IMAP mail client. I'm using a mail delimiter ("+") and mail automatically goes to a Spam folder as part of spam filtering with amavisd and spam assassin. It's configured so that folders won't automatically create; if the folder isn't there mail delivers to the inbox (so that spam doesn't create extra folders). the problem I ran into today is that a user deleted the Spam folder. While recreating it isn't that hard, is there a way I can prevent them from being able to delete specific folders in IMAP? In squirrelmail I can create "system" folders that the user can't change or delete, but that's client based. Since I don't see that ability in Outlook, can I somehow configure dovecot so the user can't delete specified folders? Thanks Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Version 2.0 with multiple IP/TLS certificate support.
by Gordon Dickens 26 Mar '09

26 Mar '09

Hello, I sent this email earlier but for some reason it did not go through so I will try again! I am using Dovecot on several servers that require multiple domain SSL certificates. I like Dovecot very much because of its speed and stability. Currently, Dovecot does not support multiple SSL certificates directly although I have gotten around this problem with multiple Dovecot instances running multiple configuration files. However, I would prefer to have one configuration file that supports multiple domain certificates. My understanding is that Dovecot Version 2.0 will have this "multiple SSL certificate" feature. So, my question is, when is version 2.0 projected to be released? Many thanks! Gordon Dickens

[Dovecot] v1.2.beta4 released
by Timo Sirainen 26 Mar '09

26 Mar '09

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz.sig This release fixes a memory corruption bug related to MODSEQ handling in earlier v1.2 releases. Memory corruption means that it's a security bug and possibly exploitable. MODSEQ code is new in v1.2, so v1.1 and older releases are not affected. Other than that, there is an ESORT bugfix and other fixes that were added to v1.1 branch too.

[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox.

[Dovecot] deliver command line options "visible" in sieve script

I use dovecot mailbox as destination of fetches from a few POP mailboxes. I would like to pass name of "source mailbox" to sieve script via deliver's command line option(s). As I understand I should use -a "mailbox@domain". How it would be accessible in sieve script? -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu It is always the best policy to tell the truth, unless, of course, you are an exceptionally good liar. -- Jerome K.

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR
by Alan Swanson 25 Mar '09

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below. I presume it's related to these MAILBOXDIR changes but the only documentation is the single line in the news for changing to ":MAILBOXDIR=mailboxes" when using dbox. Current configuration is "mail_location = dbox:~/Mail" so what exactly should be changed here?

[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] v1.1.13 and v1.2.beta3 released
by Timo Sirainen 21 Mar '09

21 Mar '09

http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz.sig http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz.sig Looks like Friday the 13th isn't the best day to make releases. :) These releases fix two bad bugs in v1.1.12. - v1.1.12's MAILBOXDIR changes broke accessing mails in some setups - v1.1.12's login_executable -D checking changes caused dovecot to crash at startup if protocols setting contained only pop3. - mbox: pop3_lock_session=yes was broken with mail_privileged_group.

[Dovecot] Single Instance Storage still on the roadmap?
by Charles Marcus 20 Mar '09

20 Mar '09

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] ESORT broken in Dovecot 1.2
by Michael M. Slusarz 20 Mar '09

20 Mar '09

Looks like ESORT is broken (just compiled 1.2 from hg 10 minutes ago). Here is the command I'm using and the corresponding error message: C: 5 UID SORT RETURN (ALL COUNT) (ARRIVAL) US-ASCII UNSEEN S: 5 BAD Error in IMAP command UID: Invalid sort argument. The corresponding UID SORT command (without the RETURN syntax) works fine: 5 UID SORT (ARRIVAL) US-ASCII UNSEEN * SORT 5 OK Sort completed (0.000 secs). michael

[Dovecot] fchown() error with Public Folders
by Stephen Carville 18 Mar '09

I was able to get public folders to work with a dedicated account for the hierarchy and ACL's for individual users. I have location defined so that each user has a local index and control files location = maildir:/usr/mail/public/cs/mail:CONTROL=~/Maildir/CS:INDEX=~/Maildir/CS Now i am seeing the folliwing error in the logs. dovecot: IMAP(stephen): fchown() failed with file /home/stephen/Maildir/CS/.Incoming/dovecot.index.log: Operation not permitted As I understand it, dovecot runs as root but the the IMAP process that servicers the request runs as the user so naturally the fchown() fails.

[Dovecot] IMAP ACLs not working
by Seba 18 Mar '09

18 Mar '09

Hi, I've some problems to get folder ACLs working with Dovecot. I've defined some folders (like drafts, spam etc.) for every user and created a dovecot-acl file in every folder so that users can not delete or rename these folders but this does not work as expected. Config ===== Debian Lenny 5.0 Dovecot 1.0.15 dovecot.conf ========= protocols = imap protocol imap { listen = xxx.xxx.xxx.xxx } disable_plaintext_auth = yes log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = yes mail_location = maildir:/home/vmail/%Ld/%Ln namespace private { separator = . prefix = inbox = yes } mail_privileged_group = vmail protocol imap { mail_plugins = acl } protocol lda { postmaster_address = postmaster(a)example.com hostname = hostname(a)example.com mail_plugins = cmusieve } auth_username_translation = %Lu auth default { mechanisms = cram-md5 passdb pam { } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } Folder structure =========== (For dovecot-acl) /home/vmail/example.com/user/.Spam/dovecot-acl dovecot-acl contains =============== owner lrwstiek For me the config looks OK and I can't find an error... When I change the dovecot-acl to "owner l" for example it seems that this change has no effect. Are there an error in my setup? Seba

[Dovecot] mbox on NFS + automount, folder creation -> mkdir_parents() failed
by Sebastian Kayser 18 Mar '09

18 Mar '09

Hi, i am about to migrate some internal imapd mboxes to dovecot. Regular access is fine, just when i want to create a folder i get the following error message in the logs: Mar 18 17:36:57 pulsar dovecot: [ID 107833 mail.error] IMAP(skayser): mkdir_parents(/home/skayser) failed: Operation not applicable /home/skayser is mounted via autofs. When i set mail_location to a subdirectory within /home/skayser, folder creation works. From looking at the truss output dovecot tries to mkdir() the parent and doesn't seem to like the ENOSYS that is returned when the directoy is an autofs mountpoint.

[Dovecot] NFS-error with dovecot 1.1.12

Uhg, I win the CluelessnUnobservant Award for this. Thanks everyone for the followups. I caught that myself yesterday and fixed the problem on Postfix's side. To sum up in case anyone else runs in to this, the mistake I made was in assuming that Postfix just made the handoff to Dovecot and that Dovecot would handle the rest, so I commented out the parts of the old config where Postfix handled this when I was using Postfix virtual transport. Once I restored those and gave Postfix the query it needed, it worked fine. Thanks for bearing with me, everyone. Kat
