by Anders 05 May '08

Hi. What does the warning "Inotify instance limit for user exceeded, disabling." mean, and how do I get rid of it? I assume that I have to change a limit somewhere? Regards, Anders.

[Dovecot] mail_chroot problems / dovecot 1.1rc4
by Michal Soltys 05 May '08

05 May '08

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

[Dovecot] libsieve support
by Mateusz Kijowski 05 May '08

05 May '08

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

[Dovecot] v1.1.rc5 released
by Timo Sirainen 05 May '08

05 May '08

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

[Dovecot] Users w/o acl access appear to be subscribed to public folders (1.1b8)
by Adam McDougall 05 May '08

05 May '08

I noticed this today, I had a user outside of our department test out dovecot. They were using squirrelmail and I noticed that dovecot thinks this user is subscribed to ALL public folders even though a dovecot ACL prevents all access. I'm pretty sure access is still denied. I was able to reproduce this with a guest account I added: l lsub "" "#shared/decs/%" * LSUB (\Noselect) "/" "#shared/decs/linuxadmin" * LSUB (\Noselect) "/" "#shared/decs/jbossadmin" * LSUB () "/" "#shared/decs/support" * LSUB () "/" "#shared/decs/receipts" * LSUB (\Noselect) "/" "#shared/decs/pcadmin" * LSUB () "/" "#shared/decs/network" * LSUB (\Noselect) "/" "#shared/decs/printmaster" * LSUB () "/" "#shared/decs/postmaster" * LSUB (\Noselect) "/" "#shared/decs/unixadmin" * LSUB () "/" "#shared/decs/security" * LSUB (\Noselect) "/" "#shared/decs/webmaster" l OK Lsub completed. This only seems to happen when the acl plugin is enabled. Without the acl plugin, these are not listed as subscriptions. After deleting /egr/mail/shared/decs/dovecot-acl-list and re-enabling the acl plugin, I get this: l lsub "" "#shared/decs/%" * LSUB () "/" "#shared/decs/unixadmin" * LSUB () "/" "#shared/decs/support" * LSUB () "/" "#shared/decs/security" * LSUB () "/" "#shared/decs/printmaster" * LSUB () "/" "#shared/decs/postmaster" * LSUB () "/" "#shared/decs/pcadmin" * LSUB () "/" "#shared/decs/network" * LSUB () "/" "#shared/decs/linuxadmin" * LSUB () "/" "#shared/decs/webmaster" * LSUB () "/" "#shared/decs/jbossadmin" l OK Lsub completed. Is it related, or is it different just because a new dovecot-acl-list got created by another user already (but is mode 700?)

Re: [Dovecot] Dovecot SASL doesn't seem to be working with Postfix

[Dovecot] Dovecot SASL doesn't seem to be working with Postfix
by Jeremy Gillick 05 May '08

05 May '08

I've tried to setup Postfix to use SASL, but it still doesn't seem to be working with Dovecot. I've set things up based on these instructions: http://wiki.dovecot.org/HowTo/SimpleVirtualInstall http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL http://wiki.dovecot.org/LDA I've compiled Postfix with Dovecot SASL and SSL/TLS support. The problems I'm seeing in Postfix are: * Virtual users are not being recognized (it'll only delivers mail for local users) * For mail it does deliver, it uses the local user permissions ( I want it to use the vmail user) * I had to modify 'mail_spool_directory' to get it to use the /home/vmail/ directory * For mail delivered to local users, it still doesn't come up in my email client when I check for new mail. I just keep feeling like the SASL integration is not working.

[Dovecot] Segfault when opening a public folder, dovecot 1.1 beta4
by Adam McDougall 04 May '08

04 May '08

I was trying to debug this with gdb, but I'm not sure how to make env MAIL=maildir:~/Maildir MAIL_PLUGINS=acl ACL=vfile gdb /tmp/imap understand the #shared/decs namespace from below so I can SELECT it. I have a number of maildirs under #ahared/decs, I tried opening at least 2 of them but dovecot gives sig 11 without a direct error about the problem. I don't think this was exactly the same problem in 1.1b3, but unfortunately I deleted all the patches I was testing with so it would be a pain to test the same situation with 1.1b3 again (although if needed, I can). If dovecot-shared exists in the folder I try to open, dovecot says: Oct 27 12:57:38 gribble dovecot: IMAP(mcdouga9): fchown() failed with file /home/mcdouga9/Maildir/dovecot11testing/public/indexes/decs/.unixadmin/dovecot.index.log: Operation not permitted Oct 27 12:57:38 gribble dovecot: child 55470 (imap) killed with signal 11 I am used to getting the first message because dovecot tries to apply perms from dovecot-shared to the index files which are elsewhere. If I open a public folder without dovecot-shared, I see no contents but it does not sig11. I am NOT using the acl plugin right now, it didn't seem to make a difference if it was loaded. When I left off with the dovecot 1.1b3 + 8 patches, I believe I was getting an assertion. Please let me know if I goofed up something, I have a strange feeling about that here, or if you need more info. I'd like to go ahead and get a gdb trace. # 1.1.beta4: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/cert.pem ssl_key_file: /usr/local/etc/apache2/ssl/cert.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot11testing/private/control:INDEX=%h/Maildir/dovecot11testing/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot11testing/public/control/decs:INDEX=%h/Maildir/dovecot11testing/public/indexes/decs list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot11testing/private/control:INDEX=%h/Maildir/dovecot11testing/private/indexes hidden: yes subscriptions: yes namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] FAQ: setting thunderbird to talk to dovecot
by Mauricio Tavares 04 May '08

04 May '08

Let's say I have a postfix box, named mail.thespider.com, which is setup to handle virtual mailbox domains. One of these domains will handle is, thespider.com, and my email address in that domain is boris(a)thespider.com. As I setup dovecot, I can telnet to the pop3 port (110) and test it by logging in as boris(a)thespider.com (I would try the imap port but I do not know how to login to imap from the telnet prompt): [raub@taz ~]$ telnet mail.thespider.com 110 Trying 192.168.1.12... Connected to mail.thespider.com (192.168.1.12). Escape character is '^]'. +OK dovecot ready. user boris(a)thespider.com +OK pass creepycrawly +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [raub@taz ~]$ How would I do the same under thunderbird from a machine in the same lan (taz.thespider.com)? It seems to keep trying to login as boris(a)mail.thespider.com, which will not fly.

[Dovecot] UID inserted in the middle of mailbox errors
by Dean Brooks 04 May '08

04 May '08

Hi, We are still getting, on a daily basis, users who cannot move messages to Trash or expunge Trash due to these errors: Mar 28 10:43:57 tm2 dovecot: [ID 107833 mail.error] IMAP(kss021): mbox sync: UID inserted in the middle of mailbox /home/kss021/Mail/Trash (3137 > 536, seq=2, idx_msgs=76) Our users have no other access to their mailbox other than Dovecot, and we are using mbox format and 1.1rc3. Deleting the indexes fixes the problem, so it seems to be a problem with index corruption and not something inherently wrong with the mailbox. That is, once I delete the index files, the problem does not come back immediately. I've seen others on the list with the same problem, but I wasn't able to find a workaround. It's happening more and more frequently. I guess what I don't understand is why Dovecot cant just mark the index invalid and purge it instead of failing over and over. I thought the whole point behind Dovecot's indexing is that it was able to detect index inconsistencies and mark the index invalid. Any help is much appreciated. Even a quick stopgap fix would be a lifesaver, short of a cronjob that just purges everyone's index files every 2 hours (which sort of defeats the point of using Dovecot). -- Dean Brooks dean(a)iglou.com

[Dovecot] Embedded From_ lines breaking Content-Length (and Dovecot)
by Lennart Lövstrand 04 May '08

04 May '08

I feel like I'm going totally crazy. Is it just me, or have embedded From_ lines really been breaking mbox messages since (at least) dovecot 1.0? I found a whole lot of broken messages in an old mailbox of mine and when I looked closer at it, it seemed like Dovecot was ignoring the Content-Length header and truncating the messages at the first embedded From_ line instead. Figuring that this probably just was a fluke / old bug, I erased the index and upgraded Dovecot, first to 1.0.10, then to 1.1.beta14, but I'm still seeing the bug -- and it's even gotten worse! Earlier versions would just quietly split the message at the From_ line, but 1.1.beta14 is more diligent and will complain with: > dovecot[44795]: IMAP(lennart): FETCH for mailbox Drafts UID 196 got > too little data: 590 vs 719 before dropping the connection and exiting... which cause Thunderbird to reopen the connection and reissue the same request... which will cause Dovecot to complain and exit again... etc ad nauseam... It's trivial to reproduce too -- just mail yourself a message with a valid From_ line in it (assuming that your delivery system isn't doing >From-escaping), or put it in a draft plain text message and save it. Then go and look in your Drafts folder... (Like this one: "From someone Tue Jan 29 03:15:52 2008") Just be sure that you can stop your spinning mail client and/or server if you're using 1.1.beta14... --- OK, I am definitely not very familiar with the Dovecot source, but I spent some time trying to track this down today and it looks to me like i_stream_raw_mbox_read is being asked to find the end of the message (at the From_ line) before mbox_sync_parse_next_mail has had a chance to parse the Content-Length header and find out how big it is. Maybe someone who knows the code better can take a look at it and tell me if I'm barking up the totally wrong tree... Thanks, --Lennart

[Dovecot] Mailbox locking issue?
by Mark Sapiro 04 May '08

04 May '08

Here's my configuration. dovecot -n # 1.0.7: /usr/local/etc/dovecot.conf protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: /var/spool/mail/%u mbox_write_locks: fcntl dotlock The above setting was just added in an attempt to resolve the issue. It was default before. mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Postfix 2.3.3 mailbox_delivery_lock = fcntl, dotlock The problem is the following. A user uses fetchmail via an ssh tunnel to download mail via pop3 every 5 minutes. This normally works fine. perhaps once a week or so, maillog shows that Postfix delivers a message while fetchmail is retrieving. Here is one such. Apr 8 19:07:20 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured Apr 8 19:07:22 sbh16 postfix/local[13745]: D959169046B: to=xxx(a)example.com>, orig_to=<xxx(a)example.org>, relay=local, delay=16, delays=15/0/0/1.1, dsn=2.0.0, status=sent (delivered to mailbox) Apr 8 19:07:22 sbh16 dovecot: POP3(xxx): Disconnected: Logged out top=2/15995, retr=0/0, del=2/2, size=15985 Five minutes later when fetchmail comes back, we see Apr 8 19:12:42 sbh16 dovecot: POP3(xxx): mbox sync: Expunged message reappeared in mailbox /var/spool/mail/xxx (UID 4683 < 4684, seq=2, idx_msgs=0) Apr 8 19:12:42 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured Apr 8 19:12:46 sbh16 dovecot: POP3(xxx): mbox sync: UID inserted in the middle of mailbox /var/spool/mail/xxx (4684 > 4683, seq=2, idx_msgs=1) Apr 8 19:12:46 sbh16 dovecot: POP3(xxx): Disconnected: Logged out top=1/46375, retr=0/0, del=1/1, size=46365 >From now on, as messages are added to the mailbox by Postfix, fetchmail keeps retrieving both old and new messages. i.e. even though dovecot's log says del 1/1 (or del n/n) no messages are actually deleted from the mailbox. This situation continues until someone accesses the mailbox locally (e.g. via mutt through a local shell) and deletes the old messages. As noted above, this has been observed a few times with dovecot's default mbox_write_locks. I have since changed that to mbox_write_locks: fcntl dotlock to be consistent with Postfix's mailbox_delivery_lock = fcntl, dotlock I don't know if that will fix the problem or not, but it seems the issue with default dovecot mbox_write_locks should have been deadlock and time out rather than what we see. Also it seems that dovecot should recover from the 'corrupt' mailbox and fix it rather than just continuing to encounter the same problem. Any ideas or advice? -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

[Dovecot] Quota not showing correctly after conversion (mb2md.pl)
by k bah 04 May '08

04 May '08

-- SCENARIO -- I'm using dovecot-1.0.5-6 on opensuse 10.3. I use the maildir quota plugin, and I'm converting mailboxes from UW IMAP (mbox) to Maildir format using that mb2md.pl script (3.10 I guess). My migration happens like this: - if a user receives mail (before ever using the new mail system), it goes to his/her inbox, dovecot proceeds normally, like when a user exists, but never received mails. Quota is shown ok. - if a user logs in before receiving any new mail, then, /var/spool/data/USER/new is created, and all converted messages are copied to that dir. If that user had deleted messages (some users mark messages as deleted, others delete for real), then a /var/spool/data/USER/.Trash/new dir is created, and messages are put there too. No other files/dirs (dovecot-uidlist maildirsize cur tmp), are created by "me" or the migration scripts. Index files (/var/spool/index/USER) are not created neither. They are created by dovecot itself. I have a problem, when a user has mails that exceed the limit in mb's (I set just size limit, no messages limit), neither "getquotaroot" (via telnet to port 143), neither webmail software (horde) show the quota usage correctly (I'm not talking about new mail, talking about those messages copied, when they exceed the size limit). Just after trying to delete messages it is shown (gives me an error message, quota exceeded, since Trash is not excluded from quota limits, for now, I'll exclude it later). This server has some issues: many old users have lots of mails, in thousands (1000-15000). Some have 50mb to 150mb of mails. The migration is part of the cleanup process. --- MY QUESTIONS --- Is it possible that the migration order (creating dirs in that way) is causing the quota usage to be shown wrong? Is it possible that the amount of messages and the size can be the cause? Misconfiguration? Other causes? How can I manually tell dovecot to recalculate the quota, after copying messages (when a user logs in, and didn't receive new mails on the new mail system, but had messages big enough to exceed the quota limit) from the old system? Should I run any commands to rebuild indexes or any operation to keep information integrity about the mails/mailboxes to dovecot, after copying the converted messages? many thanks = -- Powered by Outblaze

[Dovecot] The CONTROL problem with fs quotas.
by Jorgen Lundman 04 May '08

04 May '08

dovecot-1.0.10 on Solaris 10 x86, with NFS. We currently have the problem that when customers go over their disk quota, the dovecot-uidlist file stops them from logging in. In the interest of solving it, we considered moving the CONTROL file to a different file system. But: 1: Using CONTROL= with "%u" will quite quickly run into the problem that the directory will fill up, and hit the maximum (around 32k) or so. We have 170k users so far, and more are being imported. You could cull some from crontab or similar, but is generally a poor way to solve a problem. 2: We attempted to use CONTROL= with "%h", which would give us full directory hashing, however, we found that when it creates all the directories, it does so as the uid of the first user. So all following users (that hash in at least one part) will fail. Most likely because dovecot has already setuid()ed. Pre-creating the hashes is not feasible. 3: Using 2, we could change umask to "0000" and hence it does not matter than all directory hash node are owned by a user's id, but this unfortunately includes all other directories, and having all directories at 777 is not an option. Now, naturally, I can easily patch dovecot to call mkdir_parents with 0777 only for CONTROL. But I would rather not have local patches, meaning upgrades will be difficult. It would be preferable if: => Dovecot would call "mkdir_parents" on "%h" _before_ setuid, but create the final directory after. OR, Dovecot support (at least 2 level) directory hashing when specifying CONTROL=%1/%2/%u OR, The ability to disable dovecot-uidlist (in memory is fine). (Setting INDEX=memory does not work for CONTROL=). Are there other solutions out there? -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] used_file_size too large
by Anders 04 May '08

04 May '08

Hi. Just got this error (1.1.rc4), is it something to worry about? Corrupted index cache file /.../Maildir/.Sent/dovecot.index.cache: used_file_size too large This is a shared mailbox with concurrent access. In general, can that usage pattern mess up the index? I am guessing "no", which is why I worry slightly about the warning. Cheers, Anders.

[Dovecot] Can't receive mail for virtual user
by Jeremy Gillick 04 May '08

04 May '08

I followed the dovecot instructions ( http://wiki.dovecot.org/HowTo/SimpleVirtualInstall) to create a simple virtual user installation with the /etc/dovecot/passwd file. However, whenever I try to send a message to the virtual user, Postfix has a problem delivering it. Postfix is delivering messages to ~/Maildir, but Dovecot is trying to use /home/vmail/. How can I get the 2 apps to work together? I've set up SASL, SSL and Dovecot LDA.

[Dovecot] Client can't connect to SMTP

I've just installed Dovecot and Postfix and my email client (Mac Mail) cannot authenticate with the SMTP server.

[Dovecot] Dovecot 1.1: Ignoring Trash/Junk for maildirsize?
by richs＠whidbey.net 04 May '08

04 May '08

Hi all, We're testing Dovecot 1.1rc3, but have run into a snag with IMAP Quota's and the way Trash and Junk folders can be handled. Our MTA (Exim) quota configuration uses this option: maildir_quota_directory_regex = ^(?:cur|new|\.(?!Junk$)(?!Trash$).*)$ This completely excludes "Junk" and "Trash" from the "maildirsize" file and quota calculations. Dovecot 1.0 could do this using "ignore=Trash" (although only on one folder). Is there any way to duplicate this behavior in Dovecot 1.1? We see that "quota_rule" can be used to set an unlimited quota (storage=0), but for some reason Dovecot still records their tallies in "maildirsize", which breaks the MTA. Thanks! -Rich
