[Dovecot] Virtual Users
by Gerard Seibert 20 Oct '06

20 Oct '06

Dovecot 1.0.rc7 Postfix 2.4-20061006 FreeBSD 6.1 STABLE I have dovecot up and running with postfix. I now want to switch over to a system using purely virtual users. I have gotten postfix configured to deliver the mail to virtual mailboxes correctly. The problem I am having is with dovecot. After configuring the dovecot.conf file, dovecot will POP mail from the virtual mailboxes. However, that is only for users who are in the /etc/password file. I will have a large number of users who are truly virtual and therefore not be in that file. I know I am dumb, but I do not know how to set up either a MySQL data base, or just a plain flat file with the required information. I tried Googling, but I cannot find the exact syntax to use. Perhaps someone could point me in the right direction or give me a brief example of how to go about this. Thanks! -- Gerard "It is not the OS's job to stop you from shooting your foot.

[Dovecot] md5 password storage
by Andrey Bibiano Jardim 20 Oct '06

Hi List. I've got a dovecot running with mysql. All my users data are there. But I intend to use MD5 instead of clear passwords at MySQL. Someone can help-me? []s; Andrey Here's my dovecot-mysql.conf: # Dovecot queries db_host = localhost db_unix_socket = /var/lib/mysql/mysql.sock db_port = 3306 db = mail db_user = my_conn_user db_passwd = my_conn_passwd # # Pehapes i need to change this, but I tryied changing it do md5 with no success. # default_pass_scheme = PLAIN # # This I changed for own reasons, but works. # password_query = SELECT clear FROM postfix_users WHERE user=substring_index('%u', "@", 1) user_query = SELECT concat('/var/spool/mail/', maildir) AS mail, uid, gid FROM postfix_users WHERE user=substring_index('%u', "@", 1)

[Dovecot] 1.0.rc10 in inetd mode
by Phil Oleson 20 Oct '06

20 Oct '06

Hey.. I'm finding that I can force dovecot (setup in inetd mode) into a wedged state by spamming it with carrage returns. As I've not had enough time to familiarize myself with the code.. I thought I'd ping the list before 1.0 is christened. -Phil.

[Dovecot] Problem with indexes
by crs 20 Oct '06

20 Oct '06

Hello. Dovecot is really good software but I have one big problem with indexes. I have server with a lot of mailboxes - filesystem has quota enabled and I can't resign it from different reasons. When mailbox achieve quota size and user wants to pick mails via pop3, error "-ERR Mailbox is in inconsistent state, please relogin." is given. I know it's because dovecot can't write indexes. Is it possible to force dovecot to write indexes with definite owner/group f.e dovecot/dovecot and not owner/group of mailbox? I can set quotas for user dovecot to unlimited and problem would disappear. Thanks in advance for any answers. Best regards - Chris. ---------------------------------------------------------------------- PS. >>> http://link.interia.pl/f19a6

[Dovecot] POP State
by LDB 20 Oct '06

20 Oct '06

I upgraded Dovecot and it was smooth except some of my users using POP3 and leaving their mail on the server, are getting all their mail again. Is there a way to prevent this from happening in the future? /var/run/dovecot was kept during the upgrade ... Thanks, LDB

[Dovecot] Subscription file
by Steven F Siirila 19 Oct '06

19 Oct '06

Background: We are a UW-IMAP shop, using mbox format. (!) We are in the process of upgrading to Dovecot, hopefully to 1.0 proper. :) One of the modifications we have been using in test versions of Dovecot involve the move of the user subscription file from: IMAP-root/.subscriptions to: $HOME/.mailboxlist Rather than having to make changes to Dovecot source code each time a new release comes out, it would seem to make sense to have a way to configure this from dovecot.conf. Something like: # Default (%i denotes IMAP root): #imap_subscription_file = %i/.subscriptions # UW-imap-style (%h denotes home directory): #imap_subscription_file = %h/.mailboxlist While it makes sense to me to have the subscription file where it is in Dovecot by default, it would be a substantial undertaking to determine where to move the .mailboxlist to in our environment for each user, since there is no easy way to determine what a user's IMAP root directory is set to in their client.

[Dovecot] open-folder limit
by T. Horsnell 19 Oct '06

19 Oct '06

Is there a way to limit the number of folders a user can have open simultaneously? I seem to remember a config option which would only permit one imap process per user, and would share this between his folders, but I cant find anything relevant in the docs now. Am I talking nonsense here? I'm new to Dovecot. Cheers, Terry.

[Dovecot] Urgent - Inconsistent Inboxes
by Jakob Curdes 19 Oct '06

19 Oct '06

Hi, An urgent problem that I have : runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, nothing. For this machine we have a backup server rsyncing everything over. Now the main server went down and we started DC on the backup machine some day ago. Everything went well, besides one problem : people complained about missing mails that they had seen beforehand. When looking in the inbox, they were all there. After recreating the imap account (outlook express) or deleting the cache file (thunderbird .msf files) everything was well. But you can't really recreate all accounts after switching to the backup machine every time.... today we went back to the main server and in advance I deleted all .imap.index files hoping that they might have been the eventual cause of the problem, but no, same thing happens again. It now seems to me that this is a pure client issue, but nevertheless two questions : a) who knows a way to tell the client (OE or TB in this case) to disregard all local information and get everything fresh from the server ? b) Can this behavior be influenced from the server side? I know I'm behind with 0.99.14 but up to now there was no problem and "never change a running system". If upgrading could help, I would do it immediately. Any hints welcome, especially fast ones as tomorrow morning I have to get the clients running. Yours, Jakob Curdes

[Dovecot] LDAP Username Change
by Todd Johnson 19 Oct '06

19 Oct '06

I have a virtual setup using LDAP where the a user has an email address at 2 domain names. The want the mail kept separate but want to use the same password. I use the mail attribute and insert both email addresses. This works perfectly with deliver but opens the wrong Inbox when I IMAP. Is there a way to disable this in the conf file? host dovecot: auth(default): auth(jeff@idom.net,::ffff:127.0.0.1): username changed jeff(a)idom.net -> jeff(a)jdom.net

[Dovecot] Logging authentication failures?
by dri 19 Oct '06

19 Oct '06

I use a script that watches log files looking for failed ssh login attempts and adds firewall rules when there are enough login failures within a certain amount of time. I would like to apply this to Dovecot to automatically firewall attackers trying to brute-force an IMAP account. Is there a way to make Dovecot log authentication failures (I'm running 1.0.rc10)? In other words, can I configure Dovecot to put something in the log the instant "NO Authentication failed" is sent to the IMAP user? With "auth_verbose = yes" I can see individual authentication mechanisms fail, but I have multiple passdb sections so a failure in one mechanism doesn't mean a complete login failure. Thus, configuring the script to watch for individual mechanism failures may result in the firewalling of legitimate users. Thanks for any info!

[Dovecot] Proxy not working using passwd-file
by Clayton Epp 18 Oct '06

I've been having problems setting up my proxy using dovecot. I'm using the passwd-file for authentication as well as the regular unix passwd file. Can someone provide me with a complete example of how this should be done, I'm finding that the documentation on http://wiki.dovecot.org/AuthSpecials is sparse on the details. Please do not assume anything as I am new to both Dovecot as well as Linux (FC5).

[Dovecot] trash plugin causes crashes in quota plugin?
by Mike Horwath 18 Oct '06

18 Oct '06

I just lost my scrollback - so I'll have to recreate it the issue. Using both 1.0r7 and 1.0r10 on FreeBSD 6.1-STABLE. For the: mail_plugins = quota imap_quota that works fine (using maildir for quota plugin) But... mail_plugins = quota imap_quota trash will cause the quota plugin to die at line 156 of quota.c: root->v.deinit(root); I haven't dug through the code enough to find the actual area for this piece of code to add some debugging. Once I can generate a new traceback, I'll drop another email. -- Mike Horwath drechsau(a)iphouse.net ipHouse - Welcome home!

[Dovecot] passdb checkpassword and lastauth
by Max A 18 Oct '06

18 Oct '06

Hi. If checkpassword interface is used for working with vpopmail, function vpopmail "Record time and ip of last auth attempt" (--enable-auth-logging option for configure) won't work - the file "lastauth" is created in Maildir, but does not contain ip-address. If I had correctly understood, dovecot woldn't have set a enviroment variable TCPREMOTEIP for vchkpw. If changes are made in auth/passdb-checkpassword.c (a patch in attachment), everything will work. Probably, the patch is incorrect and does not solve all problems, however the request is to pay attention to existence of the problem. Also it is possible, that a similar problem exists with other variables TCP UCSPI protocol (http://cr.yp.to/proto/ucspi-tcp.txt) P.S. If use the interface vpopmail instead of checkpassword, the file "lastauth" will not be created at all, that is a little bit inconvenient. ********************************** System: dovecot-1.0.rc10 vpopmail-5.4.17 ASP Linux Server II (RHEL3 clone) kernel 2.4.21-47.EL.aspsmp CPU architecture: x86 (IBM xSeries 336) Filesystem: ext3 ********************************** dovecot configuration: base_dir = /var/run/dovecot/ protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes login_greeting = Ready. first_valid_uid = 89 last_valid_uid = 89 first_valid_gid = 89 last_valid_gid = 89 protocol imap { listen = 81.26.136.8:144 mail_executable = /usr/local/libexec/dovecot/imap mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { listen = 81.26.136.8:112 login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = %f mail_plugins = quota mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb checkpassword { args = /var/qmail/vpopmail/bin/vchkpw } userdb prefetch { } user = root } dict { } plugin { quota = maildir } *************************************** dovecot configure options: ./configure \ --disable-ipv6 \ --prefix=/usr/local \ --sysconfdir=/etc/dovecot \ --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --with-checkpassword \ --with-vpopmail \ --without-static-userdb \ --with-prefetch-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --with-ssl=openssl \ --with-pop3d \ --without-deliver \ --with-storages=maildir \ --with-docs ***************************************** vpopmail configure options: ./configure \ --enable-auth-module=cdb \ --enable-logging=p \ --enable-md5-passwords \ --enable-make-seekable \ --enable-file-sync \ --enable-ip-alias-domains \ --enable-clear-passwd \ --disable-roaming-users \ --disable-learn-passwords \ --disable-passwd \ --enable-auth-logging diff -ur dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c dovecot-1.0.rc10/src/auth/passdb-checkpassword.c --- dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c 2006-08-22 06:37:56.000000000 +0400 +++ dovecot-1.0.rc10/src/auth/passdb-checkpassword.c 2006-10-17 16:47:09.000000000 +0400 @@ -226,6 +226,10 @@ env_put(t_strconcat("REMOTE_IP=", net_ip2addr(&request->remote_ip), NULL)); + env_put(t_strconcat("TCPREMOTEIP=", + net_ip2addr(&request->remote_ip), + NULL)); + } if (request->master_user != NULL) { env_put(t_strconcat("MASTER_USER=",

[Dovecot] 1.0.rc10 released
by Timo Sirainen 18 Oct '06

18 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

[Dovecot] Strange POP3 problem...
by Mike Cisar 18 Oct '06

18 Oct '06

I've been having this problem for a long time now. It started when I first began to use Dovecot (0.9x) and seems to have been occurring more and more frequently as we've progressed through the betas and now into RC7. I have been kind of chaulking it up to a "user issue" since the problem only seems to occur for one user (who has one machine at his office, and one at his weekend cabin... problem occurs with equal frequency on both of his machines). Lately it's been occurring about once every couple of days, but still nothing that I have been able to reproduce with any particular email or frequency. However as luck would have it the problem occurred today while I was onsite at the client's office so I was at least able to see that end of things at the same time. Essentially the user will have a number of messages in their mailbox (today for example 13) the download of mail will go just fine until one particular message and then the download will just stop, eventually returning an error message. Trying to receive mail again will retrieve messages 1-9 again and fail in the same spot. If you log in via IMAP and delete the following message (ie. the message after the one that was last received) you can then POP for mail again and the remaining messages in the mailbox will download. In the log all we see is the following (over and over)... Aug 28 16:14:51 mail dovecot: pop3-login: Login: user=<xxxxx>, method=PLAIN, rip=vvv.www.xxx.yyy, lip=vvv.www.xxx.yyy Aug 28 16:15:32 mail dovecot: POP3(xxxxx): Disconnected top=0/0, retr=9/170375, del=0/13, size=1349520 >From the client side I get the following in Outlook Express... "Your server has unexpectedly terminated the connection..." "...POP3, Server Response: '+OK 795 octets'..." Interestingly 795 bytes is the size of the "bad" email (the one that won't download). Any thoughts? Cheers, >>>>> Mike <<<<<

[Dovecot] Index files
by Steven F Siirila 17 Oct '06

17 Oct '06

I am doing some testing with Dovecot and wondered if it was normal for the deliver program to create index files for an Inbox (the test Inbox is over 7MB), but to not update the index files after the initial creation, even though messages continue to come into the mailbox. Note that during this testing, no IMAP or POP accesses are being made. Would it matter if a command-line program such as mutt were reading/updating the Inbox in question? Shouldn't Dovecot delivery be continually updating the index files as new messages arrive in the Inbox? -- Steven F.

[Dovecot] dovecot tpop3d UIDL mbox
by antencek＠volja.net 17 Oct '06

17 Oct '06

Hello All! I am new to this list so I hope I'm not in the wrong list with my question. First, I have to say that dovecot is (in my opinion) one of the best POP3/IMAP servers arround. I especialy like its' simplicity (configuration) and powerfullness (speed, auth mechs). In my production environment I would like to cange from tpop3d to dovecot, but I have only one little problem :). This is my situation: pop3 server: tpop3d mail fromat: mbox (/var/mail/username) UIDL: tpop3d UIDL format Since there are users who let mail on server, I need to keep UIDL. The problem is that the patch which gives dovecot the capability to replay with tpop3d UIDL format apparently works only on maildir mailboxes. Is there any resonable solution to my problem? TIA. Regards, Antencek

The alarming aspect of the corruption is when it occurs at the beginning of an email (i.e. ^@^@^@From:...). Emails can be lost/appended to the bottom of the previous email. I've seen this problem several times on our deployment and tracked it down to what appears to be NFS locking issues. Are you storing mails on an NFS mounted filesystem? If so check the following... http://wiki.dovecot.org/NFS We're running dovecot-1.0 beta5 (admittedly not an rc version but >beta4 which is mentioned in the NFS wiki section) so I'm not sure the mbox rewrite from v0.99.x has fixed the problem. We had several applications accessing the mbox (Dovecot and Pine mainly). Reconfiguring Pine to use IMAP (using Dovecot) rather than write to the mbox directly appears to have fixed the problem and we have had no corruption for several months now. So, my question is am I wrong to assume NFS locking/corruption? Does anyone know if this is really a Dovecot or NFS issue? Phil

[Dovecot] 1.0.rc9 released
by Timo Sirainen 17 Oct '06

17 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz.sig Most importantly this should fix the login process problems that people have been reporting. There were also some bugs in the proxying feature. Also note the 64bit change in dovecot.index.cache files. Unless you delete dovecot.index.cache files manually, you'll these kind of error messages into your logs: Error: Corrupted index cache file ...dovecot.index.cache: registered field date.sent size changed They'll get fixed automatically of course, but it might be a bit annoying to see them. * 64bit systems: dovecot.index.cache file will be rebuilt because some time fields have been changed from 64bit fields to 32bit fields. Now the same cache file can be used in both 32bit and 64bit systems without it being rebuilt. * Added libmysqlclient workaround to conflicting sha1_result symbol, which caused Dovecot to fail logging into MySQL. + dovecot.index.cache file opening is delayed until it's actually needed. This reduces disk accesses a bit with eg. STATUS commands. + auth_cache: Try to handle changing passwords automatically: If password verification fails, but the last one had succeeded, don't use the cache. This works only with plaintext auth. - dovecot.index.cache: We didn't properly detect if some fields were different length than we expected, which caused assert crashes - Lots of fixes to login/master process handling - mbox: Fixed a bug causing "X-IMAPbase uid-last unexpectedly lost in mbox file" errors, and possibly others.

[Dovecot] Separate auth for pop and imap
by Hr. Daniel Mikkelsen 17 Oct '06

17 Oct '06

Hi. Is it possible to set up separate authentication backends for POP and IMAP for a single Dovecot instance? Or does this require two separate dovecot instances with separate config files? Specifically, I want to have one database query for IMAP and one for POP so that I can let these be separate features that I can flag in a database. -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] MBox path
by Rick 17 Oct '06

17 Oct '06

Hi, I'm having great difficulty pointing Dovecot to my MBox files. They are all in /var/spool/mail/username as textfiles.. not directories. So my guess was: default_mail_env = /var/spool/mail/%u Since %u is user. If the user is "server" I would expect it to go to /var/spool/mail/server exactly what I want. But it doesn't /var/spool/mail///home/server. If I create the directory home in /var/spool/mail and make a symlink of the username pointing to /var/spool/mail it does work. But that's a very dirty workaround I rather not use, also because we have a lot of users.. a lot of symlinks. If I set default_mail_env = /var/spool/mail, it also searches for /var/spool/mail///home/server. I feel like I've tried everything. What am I doing wrong? I'm using version 1.0.beta8, included in Fedora Core 5. Thanks, Rick

[Dovecot] Dovecot still failing with RC10...
by Timothy Meader 16 Oct '06

16 Oct '06

Hello, I mentioned back with version RC8 that dovecot was having an issue with the first login working, but all subsequent attempts failing with the error message: "Error: Maximum number of mail processes exceeded" in the dovecot log file. This is with an unchanged working conf file from RC7 (which, aside from comments, nothing has changed config-wise in the conf from version RC7). Now, the max mail processes were already set at 1024 (and I'm the only person using this server while testing), but just for the heck of it, I tried bumping the number up to 4096 and giving it another shot. No such luck. You can login once, but any subsequent attempts come back with the error I mentioned. This is making all versions above RC7 unusable for me unfortunately. I was hoping to get buy-off on switching from QPopper/UWImap to an all Dovecot solution with the pending 1.0 final, but I doubt they'll go for allow and RC being run on the production side. Two notes that might help(?): -I'm running this on Solaris 9, not a Linux box -Dovecot is not running in daemon mode, it's running through xinetd Here are the xinetd.conf sections that are relevant: defaults { #The maximum number of requests a particular service may handle # at once. instances = UNLIMITED # The type of logging. This logs to a file that is specified. # Another option is: SYSLOG syslog_facility [syslog_level] log_type = FILE /var/log/servicelog # What to log when the connection succeeds. # PID logs the pid of the server processing the request. # HOST logs the remote host's ip address. # USERID logs the remote user (using RFC 1413) # EXIT logs the exit status of the server. # DURATION logs the duration of the session. log_on_success = HOST PID DURATION EXIT # What to log when the connection fails. Same options as above log_on_failure = HOST # The maximum number of connections a specific IP address can # have to a specific service. per_source = 50 } service pop3 { socket_type = stream protocol = tcp wait = no user = root server = /usr/local/libexec/dovecot/pop3-login port = 110 flags = REUSE IPv4 rlimit_cpu = 150 instances = 80 cps = 110 10 no_access = xxx.xxx.xxx.xxx log_type = FILE /var/log/POPlog disable = no } service imap { socket_type = stream protocol = tcp wait = no user = root server = /usr/local/libexec/dovecot/imap-login port = 143 flags = REUSE IPv4 rlimit_cpu = 120 only_from = xxx.xxx.xxx.xxx log_type = FILE /var/log/IMAPlog disable = no } Thanks in advance for any help with this. --- Tim Meader CNE ISG Security NetCommerce Corporation Tim.Meader(a)gsfc.nasa.gov (301) 286-8013

[Dovecot] indexes?
by David Lee 16 Oct '06

16 Oct '06

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.). So locking is an important consideration. Decent "noac,actimeo=0" seems to address this succcessfully. But indexes... What is the best place for the index files? Logically alongside the INBOX area on the shared-NFS area? Or within each UN*X machine? (Or something else?) And why? Is there documentation of what functionality the index files provide, and how, if at all, this interacts with the locking of INBOXes (and folders). Thanks. -- : David Lee I.T.

[Dovecot] System-wide sieve script?
by Ty! Boyack 16 Oct '06

16 Oct '06

In the dovecot LDA documentation, it mentions having sieve scripts located in ~/.dovecot.sieve, which works great for per-user sieve code. I was trying to find out if there was a system-wide sieve script (maybe /etc/dovecot.sieve?) that would hopefully be run first, followed by any per-user sieve code. Anyone know if this is already possible, or if not, if there are any plans to implement this? I'm assuming one could make a kludgey fix by having every .dovecot.sieve include a system-wide file, but that would allow a user to remove that "include" if they choose. I'd like to have a centrally controlled, immutable set of rules that all mail goes through. If I missed something in the wiki or archives, I offer my apologies in advance. Thanks! -Ty!

[Dovecot] LDAP Memory Leak
by Daniel 16 Oct '06

16 Oct '06

Hi Timo I use LDAP auth on a system with around 2000 email account. I use dual OpenLDAP servers. I haven't noticed a leak of memory. Is there any more information and I will have a look to see if I can see anything that might help. Is it only affecting certain machines or all? Regards Daniel Rowe Date: Mon, 16 Oct 2006 02:39:26 +0300 From: Timo Sirainen <tss(a)iki.fi> Subject: [Dovecot] 1.0.rc10 released To: dovecot-news(a)dovecot.org, dovecot(a)dovecot.org Message-ID: <1160955566.5448.126.camel@hurina> Content-Type: text/plain; charset="us-ascii" http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX.

[Dovecot] Apple Mail quota display
by Timothy Martin 16 Oct '06

16 Oct '06

I know this isn't necessarily a dovecot issue, but I was wondering if anyone has the quota displaying correctly in Apple Mail? I have it set up and working and displaying properly in thunderbird, roundcube (webmail), and squirrelmail. But for some reason Apple's Mail doesn't show the values or its nice thermometer bar. Are there additional configuration options for quota not documented on the wiki? .tim

[Dovecot] Duplicate mails
by Vegar Nilsen 16 Oct '06

16 Oct '06

Hi, one of our customers reported a problem after we moved her maildir to another disk. (Jail in FreeBSD 6, moved to another disk with rsync.) For some reason she's seeing duplicates of almost every message from November, 2005 until June, 2006 (the move happened in September, 2006.) It seems like these mails have been respooled somehow and been inserted into the maildir with the same date and time as the original: root#loc [</var/gopostal/maildirs/wow/lina/cur>] diff 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf -rw------- 1 mailnull mail 7755 Nov 24 2005 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf root#loc [</var/gopostal/maildirs/wow/lina/cur>] ls -l 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac -rw------- 1 mailnull mail 7755 Nov 24 2005 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac As the diff command shows these mails are identical, except that one was created about 10 months after the other. 1132869216.H332479P92237.mail9.copyleft.no,S=7755:2,STac was written by Exim in November (we've configured Exim to add the size (",S=7755") to the file name), but I have no idea where the other file comes from. Could this be Dovecot that has recreated these mails for some reason? (Since the file names are different I doubt that this happened during the rsync, instead it must come from some program that conforms to the maildir standard of naming files. The mailserver had a different name back in November, mail9 was the old name, locusts is the new one.) Originally this file 1158863410.P19488Q34M511758.locusts.copyleft.no:2,STbf was named 1158863410.P19488Q34M511758.locusts.copyleft.no:2,bf which, if I understand it correctly, means it's unread. (The customer has deleted it since reporting this problem.) root#loc [</var/gopostal/maildirs/wow/lina/cur>] uname -r ; dovecot --version ; exim -bV 6.1-RELEASE 1.0.beta3 Exim version 4.60 #0 (FreeBSD 6.0) built 22-Feb-2006 13:01:52 If anybody has an idea as to what caused this I would really appreciate any pointers or info.

[Dovecot] Authenticating dovecot against Active Directory using bsdauth and login_ldap
by Martin Croker 16 Oct '06

16 Oct '06

All, I'm working in a multi-platform environment where user accounts are already held in Active Directory. I'm been trying to setup dovecot to perform user authentication against Active Directory using ldap. My Environment is: Platform OpenBSD 3.9 Dovecot Version 1.0.rc7 Active Directory Windows 2003 The approach I've taken (being the only one I was able to make work) is to use login_ldap to perform bind authentication against Active Directory/LDAP and authenticate dovecot using bsdauth. As far as I can tell the dovecot ldap authentication module requires access to the encrypted password field to which Active Directory does not permit access. Simulated LDAP login fails and when debug is enabled writes the following to /var/log/maillog ==== /var/log/maillog ================ Oct 15 20:12:27 server dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=***********************== Oct 15 20:12:27 server dovecot: auth(default): bsdauth(mcrokerx,127.0.0.1): invalid password field Oct 15 20:12:28 server dovecot: auth(default): client out: FAIL 1 user=mcrokerx Oct 15 20:12:38 server dovecot: imap-login: Aborted login: user=<mcrokerx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured ======================================= It appears that the cause of these log messages are the following lines of code in src/auth/passdb-bsdauth.c ==== src/auth/passdb-bsdauth.c ======== 29 if (!IS_VALID_PASSWD(pw->pw_passwd)) { 30 auth_request_log_info(request, "bsdauth", 31 "invalid password field"); 32 callback(PASSDB_RESULT_USER_DISABLED, request); 33 return; 34 } ======================================= These lines seem to require that the pw structure contains the encrypted password in pw->pw_passwd. Where login_ldap is used against Active Directory the encrypted password is not available to bsdauth and instead pw->pw_passwd contains '*'. If auth_userokay is called independently it is however able to authenticate the user correctly, as such I wonder if the IS_VALID_PASSWD check is actually necessary. It could be that my entire approach is wrong in which case I'm happy to be put right; however it seems that lines 29-34 need modification to correctly support this behaviour of bsdauth. This is beyond my limited ability in c but temporarily removing these lines of code from passdb-bsdauth.c has enabled me to authenticate dovecot against login_ldap (and thereby against Active Directory). My config files are: ==== /etc/dovecot.conf ================ base_dir = /var/dovecot/ ssl_cert_file = /etc/ssl/certs/server.crt ssl_key_file = /etc/ssl/private/server.key disable_plaintext_auth = no login_dir = /var/dovecot/login login_user = _dovecot mmap_no_write = yes protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain passdb bsdauth { } userdb passwd-file { args = /etc/passwd } user = root } plugin { } ======================================= ==== /etc/login.conf (exert) ========== staff:\ :auth=-ldap:\ :x-ldap-server=10.0.0.23:\ :x-ldap-port=389:\ :x-ldap-noreferrals:\ :x-ldap-uscope=subtree:\ :x-ldap-basedn=dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-binddn=cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk:\ :x-ldap-bindpw=mypassword:\ :x-ldap-filter=(&(objectClass=user)(mail=%u)):\ :datasize-cur=512M:\ :datasize-max=infinity:\ :maxproc-max=256:\ :maxproc-cur=128:\ :requirehome@:\ :tc=default: ======================================= Note: for login_ldap to work it is necessary that the user information (minus password) is replicated on the localhost. I've done this using a relatively inelegant script which for completeness is below. I guess adding some error checking would be a good idea. ==== ldapsync.ksh ===================== #!/bin/ksh ldapsearch -h 10.0.0.23 \ -D cn=UnixUser,cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -b cn=Users,dc=my,dc=domain,dc=co,dc=uk \ -w mypassword \ -v \ -x "(objectClass=user)" | while read key value ; do if [ "$key" == name: ]; then ldap_name="$value" fi # User Mail field as Unix name - remove @my.domain.co.uk if necessary if [ "$key" == mail: ]; then ldap_mail=$( echo "$value" | sed 's/@.*//g' ) if ( id 2>/dev/null >/dev/null $ldap_mail ); then usermod -c "$ldap_name" -s osbin/nologin -g staff -L staff $ldap_mail else useradd -d /home/$ldap_mail -c "$ldap_name" -s /sbin/nologin -m -g staff -L staff $ldap_mail fi ldap_name="" ldap_mail="" fi done ======================================= Martin

[Dovecot] Messages not expunged
by Jackie Hunt 16 Oct '06

16 Oct '06

Hi all, I'm doing some testing between U of Washington IMAP server (which we currently run) and Dovecot on a IBM AIX system. I created a 50M mailbox, made up of 262 msgs. I'm using a Perl Script with the imap::client module to fetch each message and then flag it for deletion. At the end of the test, I run an expunge to delete all the messages. UofW imap server ran fine, messages gone. With dovecot I found the messages were not being expunged. The log indicated they were, but then said 262 messages existed at the end. After more checking, I found the file system I was using was low on disk space (<50M). As soon as I added more disk space, and reran the test with dovecot the messages were indeed expunged. Is this normal imap protocol behavior? I thought I would see an error message or something in the dovecot log. Does dovecot duplicate the mailbox before expunge? There wasn't room on our system to do that. Thanks much for any insights/info.

Hi, I have mail box info(a)mydomain.com stored in MySQL db. But dovecot is allowing me to login as both INFO(a)MYDOMAIN.COM info(a)mydomain.com Shows two mail boxes. The small letter account is the one mail server really deliver all mails. Is there any way i can specify all login names are small letters, so that user always access real mail box ?

[Dovecot] Restricting Services (POP or IMAP)
by Odhiambo WASHINGTON 15 Oct '06

15 Oct '06

It would be great to have a HOWTO in the wiki, on how to restrict services by username in dovecot, so some users are allowed IMAP and others not allowed. As concerns restricting users by IP, I believe that is a bad idea. It's almost a useless idea, imnsho, because they can connect from another IP. It's easy to restrict services by IP using a firewall or by using inetd. -Wash http://www.netmeister.org/news/learn2quote.html DISCLAIMER: See http://www.wananchi.com/bms/terms.php -- +======================================================================+ |\ _,,,---,,_ | Odhiambo Washington <wash(a)wananchi.com> Zzz /,`.-'`' -. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +======================================================================+ Don't take life too seriously -- you'll never get out of it alive.

[Dovecot] Dovecot rc9 error (More information)
by Daniel 15 Oct '06

15 Oct '06

Hi This happens when email is copied/moved from the inbox to another folder on the same imap account. The mail client goes into a loop with the below errors logged. This is on a 64bit Linux machine using the Maildir storage format. After doing a 'rm dovecot*' from the Maildir folder of the account having the problem the client can log in again but if the client tries to copy again it gets the same error. RC9 appears to be broken on this box. I have tested connecting form a windows machine and I get the same with thunderbird. I have tried with different accounts and they get the same problem. I have down graded to RC8 and all is working OK so seems to be a problem introduced with RC9. I have a 32bit Linux server with RC9 installed which has around 2000 accounts on it and this has no problems so maybe not affecting 32bit machines. If I can give any more information please let me know. Am getting this error with Dovecot rc9 on a imap account.

[Dovecot] MySQL stored proc authorization
by Chaos Engine 14 Oct '06

14 Oct '06

On my Gentoo box until today I had dovecot-1.0_rc7 and used following entry in /etc/dovecot/dovecot-sql.conf password_query = call Authorize('%u', '%n', '%d') Simply put dovecot is calling my mysql stored routine which handles authorization. Until today, when I updated dovecot to dovecot-1.0_rc8 it worked flawlessly. With this version executing stored proc dies with: Password query failed: PROCEDURE mailsql.Authorize can't return a result set in the given context Replacing stored proc call with select .... statement does the thing, but it's stored procedures are ... generally better to do things on DB imvho :-) Downgrading to dovetot-1.0_rc7 fixes the problem immediately. Of course /etc/dovecot/dovecot.conf remains the same in either case. Is this a bug or change made on purpose? -- Chaos greets U

[Dovecot] child 29480 (auth) returned error 89, FC5, Postfix, MySql, mbox....arghhhh
by Kent Iverson 14 Oct '06

14 Oct '06

Hi all, I have been putting a small (simple?)dedicated email server together to (ultimately) host a couple of domains. I am currently getting the configuration to work with one domain w/local mbox users and then plan to extend it to virtual users and an additional domain. Dovecot has been a problem to integrate in the configuration. The basic pieces are FC5, Postfix, Dovecot, with Cyrus-sasl and MySql user/password databases. I have installed, configured, and verified Postfix, Cyrus-sasl, and MySql both separately and working together. All applications are standard Yum sourced FC5 binaries. Dovecot, however, stubbornly refuses to join the party. I have searched for clues on-line and have not found anything that has helped, thus this message. The problem seems to be tied tightly to using mySQL as an access mechanism for passdb/userdb information since if I remove that access mechanism Dovecot runs fine. The reason I am looking to use mySQL is that it seemed an easy way to have a common database for user name and domain identification with a single common FQDN login authentication format for current local users and future virtual users. As I understand it, the default PAM passwd doesn't support FQDN user names. The symptom: =========== Dovecot starts and immediately exits. Maillog shows the following immediately after executing /sbin/service dovecot start Oct 12 21:36:24 Playtime dovecot: Dovecot v1.0.beta8 starting up Oct 12 21:36:25 Playtime dovecot: child 29479 (auth) returned error 89 Oct 12 21:36:25 Playtime dovecot: child 29480 (auth) returned error 89 Oct 12 21:36:25 Playtime dovecot: Auth process died too early - shutting down Oct 12 21:36:25 Playtime dovecot: auth(default): net_connect_unix(/var/run/dovecot/auth-worker.29480) failed: Permission denied Oct 12 21:36:25 Playtime dovecot: auth(default): net_connect_unix(/var/run/dovecot/auth-worker.29479) failed: Permission denied It appears that the dovecot-auth process is immediately exiting with a non-specific error (89) and no collateral info. There are two sets of error 89's because the process count is set to 2 in dovecot.conf (see below). Looking at the messages log, you find a line reflecting the empty sockets as below: Oct 12 21:36:25 Playtime kernel: audit(1160714185.460:373): avc: denied { write } for pid=29479 comm="dovecot-auth" name="auth-worker.29479" dev=dm-0 ino=692358 scontext=user_u:system_r:dovecot_auth_t:s0 tcontext=user_u:object_r:dovecot_var_run_t:s0 tclass=sock_file There is nothing in the auth log other than happy noises from Postfix about its mySQL accesses. I am unaware of any other logs that might shed some light. Troubleshooting: ============= --- I have been using standard FC5 compiled binaries sourced through YUM for all applications. To the best of my knowledge, the package that Yum pulled for Dovecot is built --with-mysql and thus should support mysql access. I found this tidbit of info in the /usr/src/redhat/SPECS/dovecot.spec document. -- I have rolled back the dovecot.conf to remove the mysql passwd/userdb configuration leaving the default PAM configuration and found that Dovecot behaves correctly and joins the party. However, since Postfix is using mySQL data, the client FQDN login user names it uses don't match up with the simple UNIX user names that Dovecot's default PAM password mechanism is supporting (thus my attempt to get them both to use the mySql database.) So from this I know that the problem appears to be basic to startup of dovecot-auth and the mysql configuration. -- I have verified the location of the dovecot-sql.conf file as configured in dovecot.conf -- I have verified that the 'connect' parameters in the dovecot-sql.conf.work from a command line and the password_query syntax from inside mysql.

In looking into this further, I see what you're getting at. There are commands in postfix/master.cf which specify different flags depending on what external delivery program is used. However, I haven't touched that and none of the entries that came with the standard master.cf file reference Dovecot, so I'm not sure if any of those entries even apply. What I changed to cause Dovecot delivery to be initiated was simply the mailbox_command in postfix/main.cf: mailbox_command = /opt/dovecot/libexec/dovecot/deliver I have been unable to determine what, if any, changes are necessary in the master.cf file to customize what parameters are sent to Dovecot deliver.

[Dovecot] you got chocolate in my peanut butter?!
by Logan Shaw 13 Oct '06

13 Oct '06

Hey everyone, Ran into something positively perplexing today. A user came to me and said that this morning when they checked their mail, they got about 120 strange new messages. Upon further inspection, it seems the "new" messages are all addressed to a certain other different user and are all 3 or 4 months old. And looking in that other user's /var/mail/(username) mailbox, I see the same messages that arrived mistakenly. And they're not in the /var/mail mailbox of the user whose desktop computer they ended up on. So it would appear that, possibly, when this user connected to the server, they got someone else's messages! Messages that, in fact, came from an account they don't even have the password to! I'm really curious if anyone has seen something like this before. We're using dovecot-1.0.beta9, and have been since mid-June. I've never seen anything happen like this before. I'm perfectly willing to upgrade to the latest release candidate, but it's hard for me to "upgrade and see if that fixes it", because it happens so rarely and it won't be easy to know empirically. So what I'm really hoping for is confirmation that this is/was a known problem, if in fact it is. Of course, I don't know that this is a dovecot bug, but I could imagine that it might be (maybe a daemon forgets to switch users after one session is closed and another is opened?), so I thought I'd ask. I did see what looked like TLS fixes and login fixes in the changelogs, so it doesn't seem out of the question that such a bug could've existed. Some more information: I checked the user's settings on their desktop computer, where the unexpected messages appear, and sure enough, there is only one POP server account configured there, and it has the correct username. What's more, I asked them what time this happened, and they said probably at 7:00am or maybe a little earlier. Looking at my dovecot logs, I see this (where 'theuser' is the user who received the messages): Sep 28 06:59:49 myhostname dovecot: pop3-login: Disconnected: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: pop3-login: Login: user=<theuser>, method=PLAIN, rip=192.168.1.245, lip=192.168.1.20, TLS Sep 28 06:59:55 myhostname dovecot: POP3(theuser): Disconnected: Logged out top=0/0, retr=0/0, del=0/9, size=130585 So, it would seem that the user did login at the time they claimed and it was at that time (or close to it) that the weird messages appeared. Also, I checked the logs for logins from the person whose messages accidentally got downloaded, and it doesn't show them logging in until several hours later. Oh, and there are no log entries for either of the two users in question before that, at least not for over 12 hours before that. The user is running Outlook 2003, with POP3 + TLS access to the mailbox. My dovecot.conf has nothing fancy in it: base_dir = /var/run/dovecot/ ssl_cert_file = /etc/mail/certs/server.crt ssl_key_file = /etc/mail/certs/server.key protocols = imap imaps pop3 pop3s disable_plaintext_auth = no login_dir = /var/run/dovecot/login syslog_facility = local0 first_valid_uid = 100 protocol imap { } protocol pop3 { pop3_lock_session = yes pop3_uidl_format = %08Xv%08Xu } auth default { mechanisms = plain user = root passdb shadow { } userdb passwd { } } The accounts are all coming out of LDAP via nsswitch (and this is all happening on Slackware 10.2), but I'm fairly sure that's irrelevant since "getent passwd", etc. all show the right stuff. Thanks for any help anyone can give... - Logan

[Dovecot] Feature req: auth_cache_relookup
by Bill Boebel 13 Oct '06

13 Oct '06

With auth_cache_size set to a value greater than zero, when our users change passwords their accounts stop working for a few minutes, because they are trying to log in with their new password, but Dovecot is comparing that against the cached old password. It would be nice if an option could be added so that if the login password does not match the cached password, the cache value is dropped and dovecot-auth queries the userDB, but only if the previous login was successful (to avoid frequent queries for bad logins). Maybe this option could be called "auth_cache_relookup" Bill

[Dovecot] default_mail_env renaming
by Timo Sirainen 13 Oct '06

13 Oct '06

I was thinking about renaming default_mail_env to something that is more understandable. I'll keep it working for backwards compatibility anyway. How about: # Location for users' mailboxes. This is the same as the old default_mail_env # setting. The default is empty, which means that Dovecot tries to find the # mailboxes automatically. This won't work if the user doesn't have any mail # yet, so you should explicitly tell Dovecot the full location. # # If you're using mbox, giving a path to INBOX file (eg. /var/mail/%u) isn't # enough. You'll also need to tell Dovecot where the other mailboxes are and # where Dovecot can place its index files. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/variables.txt for full list. Some examples: # # mail_location = maildir:/var/mail/%1u/%u/Maildir # mail_location = mbox:~/mail/:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n # # http://wiki.dovecot.org/MailLocation # #mail_location =

[Dovecot] 1.0.rc8 released
by Timo Sirainen 13 Oct '06

13 Oct '06

I've still over 200 mails unread in the mailing list, and important things left in TODO. This release is an improvement over rc7 anyway, hopefully I'll have time to fix the rest soon. http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz.sig * GSSAPI: Changed POP3 service name to "pop", which is what the standard says * "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" + SHA1, LDAP-MD5, PLAIN-MD5, PLAIN-MD4: The password can be now either hex or base64 encoded. The encoding is detected automatically based on the password string length. + Allow running only Dovecot master and dovecot-auth processes with protocols=none setting + deliver: -f <envelope sender> parameter can be used to set mbox From_-line's sender address + deliver: Log all mail saves and failures + Tru64 SIA passdb support. Patch by Simon L Jackson. - INBOX was listed twice in mailbox list if namespace prefix was used - INBOX-prefixed namespaces were a bit broken - kqueue: Fix 100% CPU usage - deliver: Duplicate storage was a bit broken - dictionary code was broken (ie. dict quota) - SIGHUP caused crashes sometimes

[Dovecot] 1.0rc8: another problem? Possibly 64-bit index?
by David Lee 13 Oct '06

13 Oct '06

Yesterday I gave a status report about 10.rc8 in production, which mentioned a problem about "Login process died too early..." Timo suggested a patch for logging error messages. I've applied this. Others suggested increasing "login_max_processes_count". That was already way above our likely maximum, but I've doubled it anyway. Today, I've just repeated the trial, but with one significant difference and one significant new problem. The significant difference is that today's machine is not a 32-bit i686 but a 64-bit (and faster) x86_64. The new problem is lots of occurences of: [...]: IMAP([...]): file ../../../src/lib-index/mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) [...]: child 4365 (imap) killed with signal 6 and: [...]: IMAP([...]): file ../../../../src/lib-storage/index/index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) [...]: child 15009 (imap) killed with signal 6 Naturally, I've backed off quickly. Theoretically, this problem could be attributed to any of the three changes: logging, max processes, different (64-bit) machine. I suspect it's not the "login_max_processes_count" increase. Is it a side-effect of the better logging? (That is, was it always happening but the information simply not getting logged?) Note that our index files (and mail spool (INBOX, folder) areas) are on an NFS (NetApp) shared area accessed by all three classes of our machines: o existing UW-IMAP (which doesn't use the indexes) o yesterday-dovecot (32-bit) o today-dovecot (64-bit) My sneaky suspicion is that this is a subtle 64-bit-ism, either on its own, or in some sort of interaction with an indexes created from yesterday's 32-bit client. (Yes, theoretically, I could try another test to attempt to confirm or eliminate the 32/64 difference. But these issues didn't show up under testing, but only when we began trial service; I can't experiment on the users!) -- : David Lee I.T.

[Dovecot] Received dates problem in Outlook after migration
by James Wyper 13 Oct '06

13 Oct '06

Hello everyone, I've just started using 1.0-beta3 on Ubuntu Dapper, having migrated from an mbox / UW-IMAP combination to a Maildir / Dovecot one. For some reason the mb2md tool failed to recognise some of my mbox files as valid ones, so I migrated my email by running UW-IMAP, copying my folders to local storage in Evolution, then running Dovecot instead and copying the folders back. All seems OK, except that in Outlook 98 all the emails now have the date/time of their migration, not when they were received. This isn't a problem in Thunderbird or Evolution - but my wife uses Outlook and doesn't wish to switch. I've tried using touch to change the timestamps of the mails in my inbox (in ~/Maildir/cur) but this hasn't had any effect. I've also tried deleting ~/Maildir/dovecot.index and ~/Maildir/dovecot.index.cache but this hasn't made any difference either. Something else in dovecot must be being sent to Outlook as the date / time on these emails. Can anyone suggest what it would be and how I might go about changing it (to, for example, the Received: date on the email header?). Thanks in advance, James. ___________________________________________________________ Try the all-new Yahoo! Mail.

[Dovecot] Dovecot freeze - 1.0 rc7 - FreeBSD 6.1
by Floris van den Berg 13 Oct '06

13 Oct '06

Hi, One of my customers currently experiences a dovecot freeze on random accassions. Trying to figure out what's wrong with no luck. Dovecot is running fine, up until it suddenly stops responding. The log file says: dovecot: Oct 05 10:12:26 Info: pop3-login: Disconnected: Inactivity: rip=82.217.29.*, lip=85.17.42.165 dovecot: Oct 05 10:12:29 Info: pop3-login: Disconnected: Inactivity: rip=86.87.152.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:12:30 Info: pop3-login: Disconnected: Inactivity: rip=62.131.94.*, lip=85.17.42.165 dovecot: Oct 05 10:13:17 Info: pop3-login: Disconnected: Inactivity: rip=86.88.180.*, lip=85.17.42.165 No other errors are logged. When i restart dovecot it runs fine again for some time. Sometimes it works for a few days, sometimes just a few hours. There's always a point where it freezes again. Reinstalled dovecot. Fiddled a bit with the auth_worker_max_count and auth_process_size settings. No change in behavior was observed. There's no out of the ordinary cpu or memory use. Any ideas? Floris

Dovecot adds lots of spaces after X-Keywords which could just make it look like that. If it really is a blank line, then it's most likely something else than Dovecot that changes the spaces that way.

[Dovecot] proxy mode
by Jernej Porenta 13 Oct '06

13 Oct '06

Hello, I've searched the documentation for IMAP/POP3 server with proxy feature, but wiki says that this is not fully implemented yet, but wiki page hasnt been updated for a while. So is there any change since then? Because we are looking for a solution to replace the perdition POP3/IMAP proxy in front of the current UW-IMAP servers and we would really appreciate this feature, since the documentation says that proxy implementation in dovecot does not create a process for every user (problem with large number of concurrent users). Thanks in advance, cheers, Jernej

[Dovecot] Filtering Mails - how?
by Daniel Seichter 12 Oct '06

12 Oct '06

Hello, I've got some problems about understanding, how to filter my incoming mails. I am using dovecot 1.0.beta3 (ubuntu server) and want to implement a filter, where I can filter all my incoming messages (like the ones from the dovecot ml) to special folders within the mailbox of each user (for each user a special set of filters). Is there a chance to do this in dovecot or have I to use another program? My system works like: Fetchmail fetches mails from two mailservers and deliver them to the users inbox Procmail send them to spamassassin for checking about spam Dovecot provides access to the mailbox with IMAP Hope there is an easy way like module for webmin or something else. Thank you Daniel

[Dovecot] 1.0rc8 status report
by David Lee 12 Oct '06

12 Oct '06

A quick status report on how 1.0rc8 behaved in service for a few hours with several hundred simultaneous users, at a site very new to dovecot. Oh, and a question at the end. Summary: Reasonable for a first shot but one significant problem, requiring backing off. Background: We have a long-established UW-IMAP service for a user population of about 20,000 based on a few Linux (Redhat) machines running IMAP/POP and inbound delivery. We try to ensure, but cannot guarantee, that all activity for a given user takes place within one machine. Each machine mounts the INBOX area ("/var/spool/mail"; traditional UNIX mbox) via NFS with tight NFS arguments ("noac,actimeo=0", etc.) and similarly mounts the users' folder areas which are subdirs of their home directories. (We know that Mark Crispin recommends against NFS for UW-IMAP, but we seem to have been OK.) There is also some processing: .forward->"| procmail"->folder-or-inbox Each machine typically has several hundred simultaneous IMAP connections. This has basically worked well, but the UW-IMAP loading has been heavy. The plan: In an ideal world, I would like to restructure the above. But our world is not ideal, so we have to stay with the structure. But we are looking for a transparent (user perspective) migration to dovecot. The dovecot experience: Yesterday, I quietly adjusted a DNS entry to redirect one of the live email hostnames at an additional machine in the "farm", running dovecot 1.0rc8, including deliver/LDA (and taking into account some post-rc7 dovecot changes in this area). On an earlier, smaller-scale test, one problem had been some periods of "temporary authentication failures". Increasing "login_processes_count" and "login_max_processes_count" (each by a factor of 8) seems to have fixed this, and I'm not aware of any problems in that area yesterday. It basically went well. But just over two hours hours later I had to back off, because of a significant dovecot problem, namely that dovecot crashed, almost silently. The only traces of this event in the log file seem to be: Oct 10 16:26:12 [...] dovecot: child 24525 (login) returned error 89 Oct 10 16:26:14 [...] dovecot: Login process died too early - shutting down Any thoughts? Any fixes? If the problem needs debugging (or additional data/log collection) how might that be attempted in this environment? -- : David Lee I.T.

[Dovecot] Issues with Dovecot/Pam/nss_ldap
by Ejay Hire 12 Oct '06

12 Oct '06

Hello all. I have experienced an unusual behaviour from dovecot which I believe to be related to some interaction between dovecot and nss_ldap/Pam. Centos/Postfix/mbox(es)/Openldap/dovecot. The box is using PAM with ldap, and is also running BIND, SAMBA, and DHCPD. Dovecot 1.0rc2 from source. I left dovecot at the default, to use PAM for authentication and guess the mailbox. This worked well, except during peak times, dovecot would "hang", waiting an exceptionally long time after connecting before doing authentication. The users would report this as "Send/receive stuck on 64%" or something like that. During this time, I would note a number of <defunct> dovecot processes in ps. Increasing the number of idle login proceses in the pool to ridiculously high values (30) did not affect the symptom. Restarting dovecot would immediately resolve the issue. I believe this to be related somehow to dovecot's PAM interaction, because I was able to work around it by setting dovecot to talk directly to LDAP. Googling found isolated reports of similar behaviour in the Fedora Core 3 bug list at Redhat. It's rare I can help in project as important as dovecot, so I'm willing to spend some time tracking this down. What information can I provide to help? Thanks Ejay Hire

[Dovecot] Fwd: Received dates problem in Outlook after migration
by James Wyper 12 Oct '06

12 Oct '06

Having looked at this again, I think I have a hypothesis: 1. Outlook is ignoring the date/timestamps on the files in my Maildirs 2. The file names of my transferred files follow a similar pattern (they start with near-identical numbers) 3. Dovecot's file naming scheme for mails must relate somehow to the date that they were created / transferred / received 4. If I can therefore **rename** the files correctly to reflect their sending date then I can fix my problem Does this make sense? Can anyone point me in the direction of a spec that says how Dovecot names its files? Thanks, James. --- James Wyper wrote: > Date: Sun, 1 Oct 2006 21:47:02 +0100 (BST) > From: James Wyper > To: dovecot(a)dovecot.org > Subject: [Dovecot] Received dates problem in Outlook after migration > > Hello everyone, > > I've just started using 1.0-beta3 on Ubuntu Dapper, having migrated > from an mbox / UW-IMAP combination to a Maildir / Dovecot one.

I believe that when login_max_processes_count is reached (the default is 128) Dovecot is crashing rather than handling that condition semi gracefully. The reason I think this is because we have a cluster of servers that do search indexing for our IMAP mailboxes, and due to a bug this week, those servers started slamming one of our IMAP servers with rapid login failures. Dovecot crashed frequently with "Login process died too early - shutting down" while this was occurring. And then also under normal operation we were seeing Dovecot crash about once per day on random servers when that server was under a heavy IMAP load. To work around this we switched to "login_process_per_connection = no" and bumped up our file descritor limit ("ulimit -n"). No crashes since. But probably still needs to be fixed in the code. Bill

[Dovecot] Problems with LDA and vitual mailboxes
by Daniel Frickemeier 11 Oct '06

11 Oct '06

Hello, I try to set up dovecot LDA with virtual domains/mailboxes to use sieve. I use dovecot 1.0_rc7 with sieve dovecot-sieve-20060726 . All datas about the virtual domains and mailboxes are stored in a mysql-database. And without using the LDA delifer agent, everything works fine.

[Dovecot] RC8 - Creating maildir
by Luigi Rosa 11 Oct '06

11 Oct '06

I just setup a new mail server with maildir and Dovecot RC 8 I noticed that when I login via POP3 with a username that do not have a maildir yet Dovecot logs this line: Oct 11 11:46:52 gw dovecot: stat(/var/spool/mail/xxxx/) failed: No such file or directory After that Dovecot correctly creates the maildir structure Wouldn't it be better to log a message like "Creating maildir structure for user xxxxxx"?

[Dovecot] How Dovecot handles email changed by file operations
by Craig Jackson 10 Oct '06

10 Oct '06

Hi, We have been using Courier-imap for a few years. I am always in the process of reviewing competing software, and hence my interest in Dovecot. Question: If email files are moved between IMAP folders (on the same IMAP server or a different one) or deleted using shell scripts, how does this impact Dovecot's indexes or its method of keeping track of the email? How likely is index or file corruption or race condition? An example, is the centralized removal of mail in all users' Junk folder older than 30 days. We use Maildir format and Dovecot 1.0-RC7 with Mysql. We have about 150 users. Thanks. Craig

[Dovecot] POP3 - Mark messages as read
by Jose Gervasio Gomiz 10 Oct '06

10 Oct '06

Hi all. I have a little problem with Dovecot. My POP3 users can retrieve their emails without problem, but if they have "Leave mail in server" (or similar) active in their clients, their mboxes doesn't get updated marking those messages as read. If I access their mboxes locally with "mail -f username" I can see every message marked as non-read, something that never happened before when I used qpopper. I should note that when they retrieve their emails afterwards those previously received doesn't arrive again (correct behavior). My setup is: RHEL 4 Update 4 dovecot-0.99.11-4.EL4 (last version in RH Updates) mbox format, external POP3, local only IMAP (Squirrelmail) I couldn't find references to this in /etc/dovecot.conf, the FAQ or via web searching. Should I upgrade to dovecot-1.x to solve this? Even if RH doesn't support it yet? Any info would be greatly appreciated. Jose Gomiz

[Dovecot] RC8 failing...
by Timothy Meader 10 Oct '06

10 Oct '06

I just tried upgrading from RC7 to RC8 this morning, and I'm seeing an issue I've never seen before. On my first POP3 login, all is fine, but any subsequent logins seem to fail with the message: dovecot: Oct 10 11:04:31 Error: Maximum number of mail processes exceeded In the dovecot log file. I'm also oddly seeing the message: Oct 10 11:01:05 popbkup pop3-login: [ID 799321 mail.crit] Dovecot version mismatch: Master is v1.0.rc7, login is v1.0.rc8 (if you don't care, set version_ignore=yes) in the messages file on my system. Don't really understand that one, and I've done a complete shutdown of all dovecot or *-login *-auth processes prior to the "make install" for RC8. The only possible config file change I can think of that might've caused this (that was mentioned in the release notes for RC8) is the default_mail_env value, however, I believe mine is fine: mbox:~/mail:INBOX=/var/mail/%1u/%1.1u/%u This is for an actual mailbox with a two character hash for the maildrop directory. I was looking forward to giving RC8 a spin, but I've had to revert back to RC7 for now.

[Dovecot] dovecot, procmail and deliver
by David Lee 09 Oct '06

09 Oct '06

(Using dovecot 1.0 RC7 on Fedora Core 5) <scene set> Hitherto we have used UW-IMAP on a "farm" of Linux machines mounting NFS from a NetApp. (The UW-IMAP author doesn't like use of NFS, but with careful use of NFS mount arguments ('noac,actimeo=0' etc.) and trying to ensure that all activity for a given user takes place within one machine in the farm, we seem to have been OK.) We have also used UW-IMAP's 'tmail' (in sendmail.cf) and 'dmail' (from any user procmail recipes), so that access to the INBOX has been consistently UW-IMAP software. We are now considering doing a transparent migration to dovecot to improve performance. </scene> --- First: a general question: To complement the UW->dovecot migration of the IMAP daemon (reading the INBOX and folders), ought I to do a similar delivery-side migration from [UW] tmail/dmail to [dovecot] 'deliver'? It would feel safer this way, but maybe I worry too much... --- Second: "deliver" seems to add an unconditional "From " line at the start of each delivery. From sendmail, using the 'n' flag, "Mlocal F=...n..." that is OK. (Although I'm not convinced that "dovecot.deliver", nor its two-space separator (emphasis on "two") from the following date are ideal. Nor, come to that line's lack of "@somewhere".) But from a procmail recipe, I end up with two "From " lines. Surely this is incorrect. How can this be reduced to one? Shouldn't "deliver" ensure that there is only "From " line? --- Third: Would it be possible for "deliver" to do a "syslog" entry to confirm final delivery into the destination mailbox, please? (I could try and produce a patch, but someone else with more dovecot familiarity could probably do the job must more quickly and probably also more cleanly!)

Here is a patch which adds mailboxcmp() and mailboxcasecmp() functions, similar to mailbox_equals(). Names were chosen to match strcmp() and strcasecmp().

[Dovecot] which e-mail client can work with recent dovecot?
by Sergey Ivanov 09 Oct '06

09 Oct '06

Hi, I'm trying to use dovecot-1.0.rc7. Before I've used dovecot-1.0 from nightly cvs build of August 08, 2006. It worked perfectly, on Linux 64-bit, you can see spec and patches at http://www.sisyphus.ru/srpm/dovecot/ When I tried to upgrade to rc7 and to recent nightly cvs builds with the same configuration and patches (provided necessary adaptations), it builds O.K, but can not move messages from folder to folder. I've tried the following mail clients: thunderbird-1.5.0.7, evolution-2.0.2, sylpheed-claws-2.0 and KMail-1.7.1 (all from Centos-4.4). KMail refuses to copy (or to move) multiple selected messages, saying:" Error while copying messages.Connection to Server Closed Unexpectedly ...". Evolution is not able to open folders at 3-rd level (like dovecot/2006/09), or it is so slow that I was not able to test moving/copying messages in it. Sylpheed-claws died whan I tried this message copying. Thunderbird tries to move infinetly in a loop, filling the dovecot's log with lines: --- Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25177 (imap) killed with signal 6 Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25183 (imap) killed with signal 6 --- (approximitely 2 cicles per second).

[Dovecot] 1.0rc8 - not quite yet
by Timo Sirainen 09 Oct '06

09 Oct '06

OK, I know I promised rc8 today in my recent mails, but it's way too late and writing changes to NEWS file takes time. :) So I guess it'll happen tomorrow then. In the mean time it would be nice if you'd test that I didn't break anything badly with my recent changes. Especially when I changed the password verifications to detect if the password is in hex or base64 encoding based on the string length. This also allowed me to make LDAP-MD5 and PLAIN-MD5 use the same password verification function. I like this change. :) So, the almost-rc8 snapshot is in: http://dovecot.org/nightly/dovecot-latest.tar.gz I also started building dovecot-sieve snapshots: http://dovecot.org/nightly/sieve/

[Dovecot] Maildir++ quota inconsistency
by Anand Buddhdev 09 Oct '06

09 Oct '06

I've found what I think is an inconsistency in the Maildir quota implementation. According to the Maildir++ quota specification at: http://www.inter7.com/courierimap/README.maildirquota.html Maildir++ quota can be specified as maximum size, or maximum number of messages, or even both. The size specification is supposed to be in bytes. So I could use '10000000S' to set a quota of around 10MB. Now, the Exim MTA has an independent Maildir++ quota implementation, and it follows the specification, so if I set the quota in Exim to 10000000, it will work perfectly with sqwebmail and courier-imap. However, it doesn't play well with Dovecot, because Dovecot chooses to interpret the quota as kilobytes, rather than bytes. An example: If I set the quota to 10240 in Dovecot, it creates a maildirsize file with the value 10240000 in it. If I then set the quota to 10M in Exim, Exim calculates that as 10485760. It detects that the value in the maildirsize file is wrong, and recreates the file with a quota of 10485760 bytes. Exim's behaviour is consistent with the courier family of packages, as well as the specification, so I'm venturing to say that Dovecot's implementation is slightly non-standard, and should be fixed so that the quota setting is interpreted as bytes, and not as kilobytes, to avoid a situation like the above. -- Anand

[Dovecot] Password mismatch - SHA1 authentication problem.
by guard 09 Oct '06

09 Oct '06

Hello, I have problem with authentication. I'm using SHA1 passwords stored in MySQL. >From debug: Info: auth-worker(default): sql(test@mail, IP): query: SELECT password FROM vmail WHERE mail = 'test@mail' Info: auth-worker(default): sql(test@mail ,IP): Password mismatch Info: auth-worker(default): sql(test@mail ,IP): SHA1(dupadupa) != '2bca9dbe8a14811c687bb8c51c0e1cd14db8a018' I tried convert password to upper case, but it didn't help. Then I tried authentication in plain text and everything works fine... So, does dovecot crypt SHA1 using other method? I also use same SHA1 passwords to authenticate users in exim and it doesn't have any problem with that. I'm using mysql 5.0.24 and dovecot 1.0 rc7. Best regards, Tomasz Krynicki

[Dovecot] Dovecot behaviour when the server's file system fails (possible feature request)
by Timo Neuvonen 09 Oct '06

09 Oct '06

I've met a couple of times a situation, that there is something wrong with the mail server's operating system / file system, but Dovecot is still working, although it cannot any more access the mailbox files. The result is, that the imap mail client in the workstation automatically synchronises with the improperly empty-looking mailbox, effectively deleting everything previously loaded into the workstation's mail client (eg. Outlook Express) when using imap protocol. This is very annoying, especially when the workstation isn't connected with a high-speed-enough connection, since after the server is properly brought up again, reloading all the contents of the improperly emptied mail client may take considerable amount of time. This is especially the case, if the workstation has kind of mobile connection (eg. gprs) with very limited bandwith -in that case the sychronizing of eg. 20MB account may take at least from half an hour to more than one hour, and in some cases (eg. gprs roaming) also cost considerable amount of money (gprs data transfer may cost from eg. 5 to over 10 euros or dollars per megabyte, when roaming outside the phone operator's own network). So, is there currently a way to configure Dovecot in a way it would recognize that the mailbox actually is not accessible, and in that case it would return an error message to the mail client instead of returning "empty mailbox"? Of course, a smart enough mail client might also ask something from the user, but that seems not be the case either... If this behavious cannot be changed with the current configuration options, then a kind feature request to the developer: Would it be possible to change the behaviour of Dovecot when it actually can not access the mailbox files? Although the actual problem in this case is outside Dovecot, this kind of improvement would greatly improve the error tolerance of the whole system. -- TiN

[Dovecot] fd leak in 1.0rc7?
by Quentin Garnier 09 Oct '06

09 Oct '06

Hi, I just upgraded a 0.99 installation to 1.0rc7 (going from mbox to maildir along the way, but that's another story), and I'm seeing a rather fast fd quick; I already had to restart dovecot once, after a few hours. What is leaked are pipes, left open on the master dovecot process while the other end is long gone. I can't tell right now if it happens for every single login process spawned (either pop3 or imap), but at least a lot of them. FWIW, I'm running dovecot 1.0rc7 on NetBSD 2.0.3_STABLE. I'll try debugging tomorrow, but if anyone has an idea what happens in the meantime, I'm all hears. -- Quentin Garnier - cube(a)cubidou.net - cube(a)NetBSD.org "When I find the controls, I'll go where I like, I'll know where I want to be, but maybe for now I'll stay right here on a silent sea."

[Dovecot] Pop3s duplicates
by Mark Adams 09 Oct '06

09 Oct '06

Hi, dovecot 1.0 rc6 Can someone please advise on my interpretation of the following logs, Users are reporting duplicate email coming through to their inbox. (user@domain replaced actual username and domain) There are also reports of the connection seemingly freezing whilst the emails are being downloaded (pausing at a certain amount of kB then continuing after a minute or 2). info: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS info: POP3(user@domain): Disconnected top=0/0, retr=4/183443, del=0/313, size=83779942 info: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS info: POP3(user@domain): Disconnected top=0/0, retr=3/183443, del=0/322, size=84201570 In the first instance the user downloaded 4 emails totalling 183443 bytes leaving 313 messages on the server. (outlook 2003 set to leave a copy of messages on the server) second instance user downloaded 3 emails, exactly the same amount of bytes and left 322 messages on the server. Does this mean the users connection was interrupted when downloading the original emails and they attempted to be sent again a second time? how could it be that there are 9 emails left on the server if only 3 extra were downloaded? Any help on this would be much appreciated. Thanks, Mark

[Dovecot] coding techniques
by David Lee 09 Oct '06

09 Oct '06

Whilst debugging a problem in dovecot LDA over the last few days, I came across two different issues in coding techniques. (Note: Please don't take this negatively; my intent is both positive and constructive!) The front page of the website www.dovecot.org says: "it uses several coding techniques to avoid most of the common pitfalls" So I hope it is OK to follow the spirit of that with some suggestions. The two issues I encountered both seem to be fairly easy holes to fall into, and yet equally easy to avoid in the first place by using established C practices. Firstly, many 'if' statements having a single statement (whether in then or else part) are currently written in a short-cut fashion: if (condition) statement 1; else statement 2; This, though technically legal, is potentially lethal when inserting (say) debugging statements. Without diligence it is all to easy to produce: if (condition) debug 1a; statement 1; debug 1b; else debug 2a; statement 2; debug 2b; A simple edit that looks, layout-wise, as if it would do the right thing (and do in Python!); but actually radically changes the execution flow. (This is left as an exercise to the reader... to demonstrate the point.) Could I suggest that the relevant brackets be always used as a matter of course? Something like: if (condition) { statement 1; } else { statement 2; } Then the insertion of debug statements doesn't inflict surprise. (No, I didn't fall into this hole. But it is a trap waiting to happen.) Secondly, code duplication. To give one example: 'get_var_expand_table()' appears in both 'deliver/deliver.c' and 'master/mail-process.c'. (There is also a similar looking function in 'auth/auth-request.c'.) Perhaps consideration should be given to merging such instances. For instance, my woes with "%i"-expansion being treated differently in mail-reading and mail-delivery would likely never have arisen if common code had been used. I hope that helps (constructively!).

[Dovecot] rc7 crashing under heavy load
by Jeff A. Earickson 09 Oct '06

09 Oct '06

Help! Our students are back and they are pounding my dovecot server to death (ie "Login process died too early - shutting down" or "too many open files" type crash). I've had my third crash today. My setup: Solaris 10, imap and imaps, 3K users coming in via horde webmail. My current connection settings are: login_max_processes_count = 2048 login_max_connections = 4096 Q: Does raising these limits actually make my problem worse or better? Are there any other variables that I should change to prevent the "too many open files"? Suggestions? Jeff Earickson Colby College

[Dovecot] sent message not always saved in imap sent folder
by Ian Mortimer 09 Oct '06

09 Oct '06

Users who have their sent folder on the imap server report that sometimes a sent message is saved locally instead of on the server. This is the error from evolution: Error while performing operation. Failed to append to whoever@imap.server:Sent: Server unexpectedly disconnected: Unknown error Appending to local `Sent' folder instead.. We're seeing this with more than one client: evolution (linux) and thunderbird (OS X). It only happens occasionally but often enough to be annoying. It could be because the user's Sent folders are in their home directories which are NFS mounted. Are there any dovecot settings which might help? Thanks -- Ian

[Dovecot] Lost email (inbox) TWICE
by Sezer Yalcin 09 Oct '06

09 Oct '06

I have been losing my inbox. It happened twice. (2 days ago and just half an hour ago) I am using RHEL 4.0 with dovecot-0.99.11-4.EL4 System uses sendmail + procmail, dovecot is up and running. Here is how it happened: I was using Mozilla Firefox with IMAP. At the same time, I logged in from Squirrel Webmail in IMAP to the same account. Squirrel mail did not show my inbox contents. And I turned back to Thunderbird and it said, ' an error has occurred and logged to system log' and INBOX WAS LOST! squirrelmail 1.4.6 and mozilla thunderbird version 1.5.0.7 I checked server log, I see I log in but there are no further logs. This happened 2 days ago, I was wondering what the hell happened. I did not have any issues before. However recently we had a hard drive crash and all home folders are restored from backups. I assume it can be related to this. My inbox and imap folders are all in mbox format. I believe dovecot could not write to log or had something unexpected which lead to loss of inbox. There were no configuration issues and all mail system including dovecot were working fine. Now it works fine as well, but I believe it will lose inbox folder again. Has anybody experienced this? Any suggestions to recover inbox? File was reset to 0 bytes (could be deleted as well), when i did 'stat' on file, there was a file with 1 new message, all were lost. Thank you. Sezer

[Dovecot] Using NFS - which OS would you chose
by Jonathan 09 Oct '06

09 Oct '06

Hi, I'm still looking at a large (under 100,000) user deployment of Dovecot, with a NetApp NFS server as the back-end storage. I've read a few remarks about needing the latest NFS patches from Trond Myklebust to prevent lock-ups. My management would be happiest with a vendor-supported distribution (and especially Suse Linux Enterprise Server 9 or 10). We will be running on an x86 platform. Under these circumstances, which operating system/distribution would you choose? And why?

[Dovecot] Cache fields
by Tony Kay 09 Oct '06

09 Oct '06

Hi, We are using Dovecot with maildir, and the mail client requests flags, internaldate, and uid for all messages on folder open, which on average takes 3 seconds, but for large folders is much longer. It seems like I want mail_cache_fields to include "flags", but which date corresponds to internaldate? date.received? Is UID always cached for messages, or does it have to read through the directory to get them? Are there other optimizations I can do that will improve the speed of folder opens? -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 This isn't right.

[Dovecot] Date Received question
by Timothy Martin 09 Oct '06

09 Oct '06

I migrated from Courier to Dovecot, and today I notice that all my "date received" fields in my client (apple mail) show as the approx date/time of the migration rather than when the emails were received from the smtp server. Is this expected behavior? I normally sort by received date rather than sent -- since I don't care when someone sends something as much as when i get it. But those fields are totally bogus now. .tim

Hi All, Dovecot 1.0rc2. Currently having a problem with Outlook clients popping up with the error; "Your IMAP server has closed the connection.

I dont think this is a known issue that has been fixed with newer releases, as we have rc2 on another server that does not have this problem. Any help thankfully recieved. Regards, Mark

[Dovecot] Add virtual users to the Dovecot configuration
by Jens E. Madsen Jr. 08 Oct '06

08 Oct '06

Dear Dovecot Mail List, I have used Dovecot for quite a while to service remote users on my SOHO network. A local not-for-profit asked about getting their own dedicated domain name for mail. I followed: http://www.howtoforge.com/linux_postfix_virtual_hosting to set up a virtual, but the article leaves out system accounts and I have not been able to access both system and virtual users at the same time. I have the following lines: default_mail_env = maildir:/var/spool/vmail/%d/%n/ which, when commented out, works for system users default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u which, when commented out, which works for virtual users If both are uncommented, only system users work. Wiki-ing and Googling, I learned that namespace could be applied to the problem. Here is the namespace from the configuration file. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. # The default however depends on the underlying mail storage format. #separator = # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # default_mail_env, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = yes # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension or shown in LIST replies. This is mostly useful when converting # from another server with different namespaces which you want to deprecate # but still keep working. For example you can create hidden namespaces with # prefixes "~/mail/", "~%u/mail/" and "mail/". #hidden = yes #} How do I specify which users use which namespace. Is there a good description of namespaces and how to use them? Thanks Jens

[Dovecot] dovecot mailbox to csv
by John Heim 05 Oct '06

05 Oct '06

We (the Math department at the U of Wisconsin) recently switched over from another server to dovecot One thing that a lot of people here do is set up an on-line form that sends them email. They use formmail for this. I have them edit their procmail config so that all the messages go into a particular mail folder.... So far so good. With our old system, all messages in a folder were kept in a single file. With dovecot, they go into a couple of different directories. This is problematic because we often need to convert the form field data to csv values so it can be imported into a spreadsheet. So a professor can create an on-line form and end up with the data from it in an Excell spreadsheet. Slick (when it works). I understand that I can make dovecot store messages in a file by leaving the trailing slash off when specifying the folder name. Sample procmail segment: :0: * Subject:.*\[feedback\] .feedback But I can't get the feedback folder to show up in the list of IMAP folders in my mail client. I've tried Outlook Express and Thunderbird. If I put the slash at the end, it creates a .feedback folder and then I can see it in my mail client. But then I can't export it to cvs. Anybody know why I can't see the .feeback folder? Or maybe somebody has a good way to get data from the body of messages stored in a dovecot folder, for example, .feedback/cur/ and .feedback/new/.

[Dovecot] bug with rsh/ssh connections
by David Lee 05 Oct '06

05 Oct '06

(Using rc7 code) There seems to be a bug in rsh/ssh-style connections. For reference, on a normal imap connection (port 143, 993, etc.) things are OK. The imap session ends (from a client-end command "a logout") thus: --- a logout * BYE Logging out a OK Logout completed. Connection closed by foreign host. unix-prompt% --- But when the connection had been established using rsh or ssh to the servers's "/etc/rimapd" which contains: exec /usr/dovecot/sbin/dovecot --exec-mail imap the session ends thus: --- a logout * BYE Logging out a OK Logout completed. imap(<username>): Info: Disconnected: Logged out unix-prompt% --- Note that additional, protocol-breaking, "imap(...): Info ..." line. This seems to be coming from "imap/cmd-logout.c" calling: client_disconnect(client, "Logged out"); which in turn ("imap/client.c") does: i_info("Disconnected: %s", reason); On the imap connection, this "i_info(...)" output goes (correctly) to syslog, but on the rsh/ssh connection this output seems to go to something like stdout. This strongly suggests a bug: an inconsistency between the two connection types, possibly regarding the way that stdout, stderr, syslog etc. are initialised, assigned, adjusted, etc. -- : David Lee I.T.

[Dovecot] Bug: auth_cache breaks master password feature
by Bill Boebel 05 Oct '06

05 Oct '06

When you set auth_cache_size to a value greater than zero, it breaks the master password feature in Dovecot. It appears that during a cache hit, Dovecot attempts to query the userdb for use the master user's home directory and other settings, rather than querying for the userdb settings of the user that the master was trying to log in for... causing the login to fail. Perhaps caching the userdb settings in addition to the passdb settings (since that is on the TODO list) would indirectly fix this problem. Bill

I have been using bincimap with vpopmail for awhile and would like to give dovecot a try. Does anyone has any success configuring dovecot with vpopmail? I have installed dovecot but didn't manage to get it up with vpopmail. It will be good if someone can share their settings on dovecot.conf with me. Thanks

[Dovecot] Can't load certificate file: cert already in hash table

[Dovecot] No inbox for user error
by Ron 04 Oct '06

04 Oct '06

Hi, I'm getting 'no inbox for user' error. Set up sendmail, and can send and receive mail using Webmin/Usermin both to internal addresses and external ones. But Dovecot gives the no inbox error. I've tried telnetting in and get: +OK dovecot ready. USER myob -ERR Unknown command USER myob +UK PASS <password> +OK Logged in. -ERR No INBOX for user. No idea why the first USER command gives an error. And, of course, when I try using Evolution I get 'Cannot get POP summary'. The Dovecot config file, less all the commented out bits is: imap_listen = [::] pop3_listen = [::] imaps_listen = [::] pop3s_listen = [::] ssl_cert_file = /etc/pki/dovecot/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem login_dir = /var/run/dovecot-login login_chroot = yes login = imap login_user = dovecot login = pop3 default_mail_env = mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root Any and all ideas very welcome. I'm a total newbie at this server business... Thanks in advance. Ron

[Dovecot] Dovecot as LDA
by Gerard Seibert 03 Oct '06

03 Oct '06

FreeBSD 6.1-RELEASE-p8 postfix-current-2.4.20060903,3 dovecot-1.0.r7 I am experiencing a problem with dovecot as an LDA. It will not deliver mail unless the mail directory is chmod'd to 1777. Below is an example of the log file output. The dovecot.log file had over a hundred entries similar to this: deliver(gerard): Error: open(/var/mail/.temp.scorpio.seibercom.net.1123.cd38cd4d82e1368f) failed: Permission denied deliver(gerard): Error: file_lock_dotlock() failed with mbox file /var/mail/gerard: Permission denied Obviously the /var/log/maillog had similar fail warnings. By changing the permission to 1777 on the /var/mail directory and running postsuper -r ALL, I was able to get the mail delivered. What I am trying to determine is if I really should have those settings on the directory, or if I have something configured wrong in either postfix or dovecot. Postfix will deliver mail without any problem so I think it has to do with dovecot although I am not sure what. -- Gerard

[Dovecot] [SOLVED] quota with: postfixadmin, postfix, mysql & dovecot
by Peter Veerman 01 Oct '06

01 Oct '06

Hi, I'm quite new to dovecot but already quite satisfied. Your documentation in the wiki is great but on quota + mysql it is not very clear. Because of the previously mentioned I have got the following note to make which you will hopefully use to adjust your wiki documentation on per-user-quota + mysql. I've searched your mail archive as good as possible and found no messages on this. If already messages have been exactly on this topic I want to apologize for sending this one. The notes I want to make is about this page: http://wiki.dovecot.org/Quota I'm using postfix + postfixadmin & mysql and dovecot (previously I used courier-imap instead of dovecot). The problems I ran in to was with setting up the per-user quota, as the explanation at the wiki is quite vague. For instance, the dict plugin is used to keep the quota counters in the mysql backend but only one single line shows how to set-up a per user quota. Setting up a per user quota where the max-quota is stored in mysql should be made making use of this setting: ========== user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_bytes AS quota FROM users WHERE userid = '%u' ========== nowhere is mentioned that this should also! be set: =========== protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } =========== the second point I want to make is that the mysqlquery is incorrect as || does not do the job of joining the two strings. Secondly is dovecot making use of kilobytes instead of bytes like postfix (and postfixadmin) does. For this I have found the following solution: ========== user_query = SELECT maildir, 125 AS uid, 125 AS gid,\ CONCAT('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota \ FROM mailbox WHERE username = '%u' AND active = '1' ========== Here I select the quota field from the mailbox table. This is then divided by 1024 (1Kbyte) and ROUNDED off in order to get rid of the .00 that results from this division. Greetz, Peter Veerman pveerman NO-SPAM at NO-SPAM hackwerk DOT net

[Dovecot] Passdb passwd on FreeBSD
by Jim Flowers 29 Sep '06

29 Sep '06

I am trying to use dovecot for both virtual and local pop3 mailboxes. When I try to access a local account, I get an "unknown user" reject from 'passdb sql', as expected. However, I also get a reject from 'passdb pam' with the message: dovecot: auth(default_with_listener): pam(username(a)domain.tld,###.###.###.###): pam_authenticate() failed: authentication error. Is this because it is trying to authenticate username(a)domain.tld instead of just username? What can I do about it? Although I have a block for 'passdb passwd' following the 'passdb pam' block, there is nothing in the log. Why is this, I wonder? Any help to point me in the right direction will be appreciated.

[Dovecot] Quota plugin rewrite
by Timo Sirainen 28 Sep '06

28 Sep '06

Backported from CVS HEAD to branch_1_0. You can get it as a patch from http://dovecot.org/patches/1.0/quota-rewrite.diff New features include support for multiple quota roots, so you could have eg. per-user quota and a larger domain quota (although no backend actually supports this yet..). The more important feature is that you can configure specific mailboxes to have a bit more space available for them, such as Trash or Spam. The configuration has also changed. Normally you'd use something like this: quota = maildir # 1GB quota in general quota_rule = *:storage=1048576 # Trash mailbox gets 100MB more (so max. 1,1GB) quota_rule2 = Trash:storage=102400 # Spam mailbox gets also +100MB (still maxes at 1,1GB, not 1,2GB) quota_rule3 = Spam:storage=102400 You can place all the above into plugin { .. } section in dovecot.conf. In userdb if users have different quotas you'd then need to override only quota_rule (not quota, quota_rule2 and quota_rule3). I tested quickly that this seemed to work as described above. Please test and report. :)

[Dovecot] LDA and chroot
by Uldis Pakuls 28 Sep '06

28 Sep '06

Hi, I'd like to ask: is it possible to use Dovecot's LDA with mail_chroot variable set, e.g. "mail_chroot = /serv/storage19/vmail"? Without "mail_chroot" set all works fine. If mail_chroot is set and user database contains relative paths to home directory (without chroot part like "domain.net/user") deliver ignores this and tries to work at real root, while imap and pop3 processes founds home directory correctly. If users database contains full paths deliver works correctly, but imap/pop3 processes tries to access chroot directory + full path (and fails). Home directory in form "/chroot/path/./domain.net/user" solves the problem..., but as I understand, it is jut form to override default. Thus I can't find a way to correctly set default chroot path. Any suggestions? Tnx, Uldis

[Dovecot] LDA directly to Maildir/cur
by Scott Murman 28 Sep '06

28 Sep '06

i'm tired of dealing with buggy clients so i'm moving more processing into the server-side. i configured procmail as LDA with maildir-style mailboxes. i would like to simulate an automatic "mark as read" feature during procmail processing. simplest way looks to be forcing delivery directly to Maildir/cur instead of Maildir/new, but i suspect this may screw up dovecot. will this work? is there another (better) method? -SM-

[Dovecot] dovecot checkpassword passdb and vmailmgr
by Mij 28 Sep '06

28 Sep '06

hello some times ago I posted some patches to workaround vmailmgr not fitting into dovecot's passdb-checkpassword authentication module. Yesterday I spent some spare time for carrying out a cleaner solution for this problem. Check out these patches. If you're not interested in merging them, I will make them available at the same page I used for the former solution [ http://mij.oltrelinux.com/net/dovecot-qmail-vmailmgr ]; there were some 20 people/month that checked it out. This is a brief explanation of the patches: The root of all evil is that the checkpassword interface [ http://cr.yp.to/checkpwd/interface.html ] leaves room to interpretation when the scope is not system login. Vmailmgr and vpopmail, for example, collapse many mail users on the same system account. So, what "home" is here is not specified. In the case of vmailmgr, it's "checkvpw" sets HOME to the system user's home, and returns the path of the actual mail user differently. The solution I applied for this problem is to generalize the process that fetches authentication data (what currently is "checkpassword- reply"). I was set up for a specific passdb-vmailmgr module, but this would have seen a lot of code replication. Similarly (but I did not inspect further), I guess vpopmail can fit in this solution as well. So 1) provide a module "vmailmgr-reply", with the same behavior as checkpassword-reply, that's aware of the way checkvpw returns accounting information and pass this back to dovecot transparently so, this patch ships vmailmgr-reply along with checkpassword-reply (name them "fetcher"s for brevity) The idea is that every checkpassword-compatible module may have its own fetcher for passing correct info back to dovecot. Now with this generalization, the user must be able to specify if its checkpassword module needs a custom fetcher, and if it does, what's its path. So 2) modify auth/passdb-checkpassword.c and pump "args =". By default it takes the path of the checkpassword module (e.g. "checkvpw"), now it can be appended another field, that is the path of the custom fetcher. If this optional is omitted, the default checkpassword-reply will be used, and the cp module is supposed to behave like dovecot expects from it. Otherwise, a comma appear after the first path. e.g. passdb checkpassword { args = /xyz/checkvpw,/libexec/vmailmgr-reply } if one needs to specify paths with commas in the first one, commas can be escaped with \ (eg args=first\,path,second_path) Last but not least, the patch addresses again the problem with colons in paths. Currently, dovecot dictates no colons can exist in mailbox path names. In UNIX, no such constraint exist. Moreover, paths with colons are common when working specifically with qmail (see dot-qmail). When dovecot encounters ':', it truncates the path. This way, for example, if the authentication module returned home "/ path/name:surname", dovecot will truncante it to "/path/name". If name exist, name:surname will browse his mail without effort. All this comes from dovecot parsing params on MAIL environment (INDEX, INBOX, CONTROL), but it also happens if none of them was actually specified. So 3) modify lib-storage/index/maildir/maildir-storage.c for fixing the parsing problem with the mail environment. [ I did not provide the same fix for the remaining storages, but this can easily be done by copy/paste if convenient ]. For simplification and without loss of generality, this fix mandates ":INBOX=", ":INDEX=" and ":CONTROL=" params to follow in this order, if they appear. [ a minor patch agains auth/Makefile.am is provided for including vmailmgr-reply when building the rest of the auth stuff ] Any comment on this is welcome for discussion. bye

Delivery is handled by the MTA. Dovecot just needs to know where to access it. By default, for example, with Sendmail, it will place the email in /var/spool/mail (unless you change some back-end code somewhere along the line), and then you can use procmail (with a global procmailrc file in /etc) to place the mail where you want it to go.. I haven't used UW-IMAP in a while now (well over a year and a half). I stopped using it at all of my supported sites because, even though it was simple to manage, it was just way too slow. From what I remember, the UW implementation is such that UW-IMAP will read from the user's mbox file if it exists, and if it doesn't, it will read from <spooldir>/<username> (in this case, /var/spool/mail/user). UW-IMAP (or any IMAP) wouldn't actually do the delivery, so writing to the spool directory temporarily and then moving it to the home directory shouldn't actually happen. However, I don't truly remember how it worked under the hood, but that just doesn't seem right to me (too much chance for conflict). I do remember (back in the day) the headaches we would get when trying to debug a "lost mail" problems (with a centralized /var/spool/mail directory) and it turned out the user in question had created an mbox file which had next to nothing in it. :) -Rich

[Dovecot] syslog messages
by Rich West 27 Sep '06

27 Sep '06

(I sent this last night, but to the wrong address.. argh) After an upgrade to FC5, and a rebuild and install of dovecot 1.0RC7, I've been getting a LOT of syslog messages like the following: Sep 26 21:47:55 myhost dovecot-auth: nss_ldap: reconnected to LDAP server ldap://ldap.mydomain.com after 1 attempt Now, everything is working fine as far as I can tell (it's only been a rocky day since the upgrade.. and that was littered with other LDAP related problems), but I was wondering why it was even using nss_ldap... I have dovecot configured to connect to LDAP directly. My dovecot.conf contains: auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain ... passdb pam { } ... # LDAP database #passdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap.conf for example #args = #} ... # LDAP database userdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap.conf for example args = /etc/dovecot-ldap.conf } And I am wondering if I missed something obvious here... I'm going to try commenting out the "passdb pam" section, uncommenting the "passdb ldap" section and see if that allows for everything to go directly to LDAP (and not rely on nss_ldap or pam_ldap). -Rich

[Dovecot] SSL_accept failed
by Timothy Martin 26 Sep '06

26 Sep '06

Hello, I'm new to dovecot. I just installed it a few days ago on FreeBSD via the ports and got it up and running without too much trouble. Although yesterday I turned on the SSL/TLS features and tried to get secure connections to work. I don't get any error messages when launching dovecot, I saw it successfully create the SSL parameters after first enabling the feature yet I can't seem to get a successful connection. Normal non- ssl connections work fine. What happens: 1) my client claims to be attempting the connection. 2) things go on for some time with nothing happening 3) finally the dovecot log pops up with these messages dovecot: Sep 09 02:25:23 Warning: imap-login: SSL_accept() syscall failed: EOF [x.x.x.x] dovecot: Sep 09 02:25:23 Info: imap-login: Disconnected: rip=x.x.x.x, lip=x.x.x.x, TLS handshake dovecot: Sep 09 02:26:23 Info: imap-login: Disconnected: Inactivity: rip=x.x.x.x, lip=x.x.x.x, TLS handshake FYI: I've regenerated a fresh cert and key, just for dovecot and I'm using Mac OS X's Mail client.

[Dovecot] Not getting new mail notification
by Robert Creager 26 Sep '06

26 Sep '06

Hey all, I'm having no luck getting new mail notification except in two mail folders (using maildir w/procmail delivery). I'm using three different clients (sylpheed-claws 1.9.14, Thunderbird 1.5.0.5 and a newer version of Horde). None of them are getting new mail in any except these two folders (inbox and 1 other). If I browse to the folders, still nothing. If I browse to the folders with Horde, I see the new mail, but not always in the other clients. It's hit or miss if the other clients get notified of the mail, but the mail is moved from the new folder. I'm subscribed to the folders and have them to be checked for new messages (in Thunderbird). I tried using dnotify, and things got worse (no folders updated). I've over 350 e-mails sitting in new folders right now: [robert@thunder Maildir]$ ls .*/new | wc 397 332 12925 One interesting item I noticed is that if I touch a file in a new directory (or vi it), I immediately get notification of the mail (and it gets moved from new to cur). I'm running dovecot 1.0 RC7 configured as ./configure --sysconfdir=/etc/dovecot --with-pgsql --with-pam --localstatedir=/var with the following changes to the config: base_dir = /var/lib/dovecot/ protocols = imaps ssl_cert_file = /etc/ssl/dovecot/certs/dovecot.pem ssl_key_file = /etc/ssl/dovecot/private/dovecot.pem default_mail_env = maildir:%h/Maildir verbose_proctitle = yes protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } I'm running dovecot through xinetd: service imaps { disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/local/libexec/dovecot/imap-login flags = IPv4 server_args = --ssl } Linux thunder.logicalchaos.org 2.6.12-12-3 #5 SMP Wed Feb 1 23:59:03 MST 2006 i686 AMD Athlon(tm) MP 2600+ unknown GNU/Linux Help?

[Dovecot] Preforming an action/trigger after a user successfully authenticates
by Dan Trainor 26 Sep '06

26 Sep '06

Hi - I have searched the docs for v1.0 RC7, but cannot find what I'm looking for. What I'm ultimately wanting to do is have Dovecot preform some action, or a trigger, when the user is successfully authenticated. Even more specifically, I'd like to run another SQL query to record a date/time for last authenticated login. Short from running a script during logrotate, or constantly tailing the log, is there any mechanism in Dovecot that would allow me to do this? Again, all I'm looking to do is to record the last date/time that someone successfully logged in, into a MySQL database. Thanks! -dant

[Dovecot] DSpam mysql-plugin (was DSpam plugin)
by Michael Blinn 25 Sep '06

25 Sep '06

After wrestling with Johannes's original plugin, I had a go at the mysql plugin that Tim wrote, as described here: http://members.plug.org.au/~linuxalien/dokuwiki/projects:dovecot-mysql-dspa… I kept getting "Error: imap dump-capability process killed with signal 11" when attempting to start dovecot with this plugin. I traced the error to line 656 of master-settings.c in the dovecot source, in the 'get_imap_capability' function. In this function, it notes: "Reloading configuration. Don't try to execute the imap process again. Too risky and the wait() call below will break it anyway. Just use the previous capability list we already had generated." I changed the source so that the function always ran " set->imap_generated_capability = p_strdup(settings_pool, generated_capability); return TRUE;" instead of going through the function where it had on the wait described in the comments. Now, voila. Dovecot starts without complaint, the plugin works, the delivery and moving of email works. I'm assuming I've screwed something up by skipping the rest of this get_imap_capability function. My C skills are a few years rusty. What are the ramifications of skipping the remainder of this function? Thanks, Michael

[Dovecot] Moving to dovecot
by Ian C. Quorn 25 Sep '06

25 Sep '06

We're in the process of moving to Dovecot. We're currently running UW-IMAP live with Dovecot 1.0rc7 on alternate ports for testing. We're set to switch to Dovecot tomorrow morning, and I'm sure I'll have lots of stupid questions once that happens. So I guess you can consider this message an introduction as well as a preemptive apology. Our setup: our mailserver is a SunFire 880 running solaris 8. Inboxes are stored in /var/mail, home directories are in /home. Mailboxes are mbox. Both /home and /var/mail are NFS-mounted from a NetApp filer. Indexes are stored in /dovecot (this is a partition on local disk). We have about 500 users accesing their mail on this server. Supported clients are Outlook, Mac Mail, and Thunderbird (both PC and Mac). Many people access their mail via webmail (IMP Horde) instead of or in addition to using a normal client. We also have a few people who use Pine. Authentication is against the local shadow file. Given this setup, do the following config lines seem sane? login_process_per_connection = no login_max_connections = 256 default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u:INDEX=/dovecot/%u namespace private { separator = / prefix = inbox = yes } # for backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } mail_read_mmaped = no mmap_disable = no mmap_no_write = no lock_method = fcntl mbox_read_locks = dotlock mbox_write_locks = dotlock imap_client_workarounds = outlook-idle tb-extra-mailbox-sep pop3_uidl_format = %08Xv%08Xu pop3_client_workarounds = outlook-no-nuls oe-ns-eoh The namespace stuff came from http://wiki.dovecot.org/Namespaces - it was listed as a way to allow backwards-compatability with UW-IMAP. So, anything there look like a bad idea? Any other config parameters I might want to tweak, tune, or otherwise take a look at? So far dovecot's been pretty much trouble-free in our testing. But I have noticed some error messages in the logs. Anyone know what these mean? Are they anything I should panic over? dovecot: Sep 25 09:34:19 Error: IMAP(cliftoja): UIDVALIDITY changed (1034876030 -> 1159201281) in mbox file /home/wcts/cliftoja/mail/Common installation codes dovecot: Sep 25 09:50:24 Error: IMAP(cliftoja): UIDVALIDITY changed (1156881790 -> 1159202005) in mbox file /home/wcts/cliftoja/mail/Junk dovecot: Sep 25 10:04:01 Error: imap-login: Master sent reply with unknown tag 180 dovecot: Sep 25 10:04:01 Error: child 1078 (login) returned error 89 dovecot: Sep 25 10:18:58 Error: login: tried to change state 0 -> 44 (if you can't login at all, see src/lib/fdpass.c) Thanks in advance, and here's to (hopefully) a trouble-free Dovecot migration (hey, it can't be worse than UW-IMAP).

We're running Dovecot 1.0.rc7 on a different port on our live server (we're generally live with 1.0.beta5) and after a HUP to reload the user database (in a passwd-file) this morning we got:- > dovecot: Sep 22 07:45:05 Info: IMAP 14482 someuser xxx.xxx.xxx.xxx : Disconnected in IDLE > dovecot: Sep 22 07:45:05 Warning: imap-login: SSL_read() syscall failed: No route to host [xxx.xxx.xxx.xxx] > dovecot: Sep 22 07:45:05 Warning: SIGHUP received - reloading configuration > dovecot: Sep 22 07:45:05 Error: Login process died too early - shutting down > dovecot: Sep 22 07:45:05 Panic: file ioloop-poll.c: line 105 (io_loop_handle_remove): assertion failed: (index >= 0 && (unsigned int) index < ctx->fds_count) and Dovecot had died. "someuser" was me, and I'd left my Thunderbird client logged in (via IMAPS) by mistake when I hibernated my PC last night. I'd seen exactly the same assert on a test box the day before yesterday, (this time without a machine hibernating):- > dovecot: Sep 19 19:00:45 Info: imap-login: Aborted login: user=<testuser>, method=PLAIN, rip=yyy.yyy.yyy.yyy, lip=yyy.yyy.yyy.yyy, secured > dovecot: Sep 19 19:07:42 Warning: SIGHUP received - reloading configuration > dovecot: Sep 19 19:07:42 Error: Login process died too early - shutting down > dovecot: Sep 19 19:07:42 Panic: file ioloop-poll.c: line 105 (io_loop_handle_remove): assertion failed: (index >= 0 && (unsigned int) index < ctx->fds_count) Where yyy.yyy.yyy.yyy is actually the test box (I was logging in from the server itself using "openssl s_client"). The thing is, I was hoping to upgrade everyone (~20,000 users) to 1.0.rc7 next Tuesday, but now I'm not so sure!

[Dovecot] Need to detect event: a user move a message to a “spam folder” (for antispam filter)
by Naefen Raphaël 25 Sep '06

25 Sep '06

I’m writing an immune system based antispam filter. I need to detect when a user move a message to her spam folder (to inform the filter). I I found “cmd_copy” in imap library so I detect the copy event. But at this level I wasn’t able to find info about which mail and which user copy this message. My question is: Were I can find user Info to know how is moving this message in the spam folder. Ideally if I can have information about message (content or id) will be perfect. Thanks

BUG in rc7 (and probably from much earlier). The LDA 'deliver' fails to honour any uid (%i) setting in dovecot.conf. So delivery and reading happen in different places if 'default_mail_env' uses a '%i' variant. Clearly incorrect behaviour. Attached is a draft of a patch which fixes the problem. Please could the patch be reviewed and, in some form, applied? Thanks. -- : David Lee I.T.

[Dovecot] PAM authentication problem: MD5 vs crypt
by bhayden＠umn.edu 23 Sep '06

23 Sep '06

Here's a strange one. I have Dovecot set up on Solaris 9. The auth portion of the config is straight out of the box. Using PAM. We have most users in a dbm file which is just a series of key/value pairs: key is a username, and value is a string equivalent to a shadow entry. nsswitch.conf entry: passwd files dbm. For historical reasons, some users have a classic 13-character Unix crypt password hash, while others have a 34-character MD5 hash. Here's the situation: User location pw Hash Auth succeeds/fails ---------------------------------------------- files crypt succeeds dbm crypt succeeds files MD5 succeeds dbm MD5 FAILS After two days of research, trussing, and etc, I am stumped. Does anyone have a thought? -Brian

Hi List, I'm setting up a new Dovecot server and am having some issues getting Dovecot to see the mailbox correctly. I already have several mailboxes (From another Dovecot server) but my new install does not see them. I'm running Ubuntu 6.06 w/ Dovecot 1.0.beta3. When I try to login, I get the following in the log.

[Dovecot] most of INBOX missing?
by William Lott 22 Sep '06

22 Sep '06

Greetings. I'm having an issue with dovecot that I'm hoping that someone can help me with. Most of the mail in my INBOX has mysteriously disappeared and I'd like to get it back. It's all in the ~/Maildir/cur directory and dovecot reports that 1048 messages exist when given the SELECT imap command. But Thunderbird and the SEARCH imap command only list 25 messages: [wlott@rootbeer ~]$ ls Maildir/cur | wc -l 1048 [wlott@rootbeer ~]$ MAIL=maildir:~/Maildir /usr/libexec/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE] Logged in as wlott x SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $MDNSent $Label1 $Forwarded Junk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $MDNSent $Label1 $Forwarded Junk \*)] Flags permitted. * 1048 EXISTS * 0 RECENT * OK [UIDVALIDITY 1117080198] UIDs valid * OK [UIDNEXT 1700] Predicted next UID x OK [READ-WRITE] Select completed. x SEARCH ALL * SEARCH 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 x OK Search completed. [wlott@rootbeer ~]$ I'm running dovecot version 0.99.14-8 under Fedora Core 4. I saw on the dovecot website that 0.99 isn't supported anymore, but I'm hoping that someone can help me recover my lost email none the less. Thanks, -William

[Dovecot] Limiting number of IMAP connections per user
by Simon L Jackson 22 Sep '06

Hi, Is there a way of limiting the number of IMAP connections (i.e. processes) per user? Despite asking users to set their email client settings to limit themselves to 2 connections, some still have this set to 10 or more.
