[Dovecot] mailbox from ldap and indexes
by Stian Jordet 21 Dec '05

21 Dec '05

Hi, because of quota, I would like to have indexes on another filesystem then user's maildir. This I can do with "default_mail_env= maildir:/% h/Maildir:INDEX=/var/indexes/%u" or something. But when I get the users mailbox location from ldap, there is no way to set the index? I guess I can make the ldap entry contain the INDEX as well, but I would like to use the ldap entry in the exim conf as well, to tell exim where to write the mails... Is there a way I haven't thought of yet? I have this in dovecot-ldap.conf now: user_attrs = uid,homeDirectory,mailbox,uid,uidNumber,gidNumber If I could do something like: user_attrs = uid,..,"maildir:" . mailbox . ":INDEX=var/indexes/%u",... that would have been awesome. Best regards, Stian

[Dovecot] Another "Too many files open" post
by Andy Cravens 21 Dec '05

21 Dec '05

I'm running Solaris 9 Sparc with Dovecot alpha 5 and using maildir format.. I noticed in the log file the following error: dovecot: Dec 20 15:54:18 Error: imap(xxxxxxxx): open(/export/home/xxxxxxxx/mail/.Sent Messages/cur/1135013649.002916.mbox:2,Sab) failed: Too many open files I called the guy and asked him what he was doing... synching his folders. It hung for a while but finally finished. I searched the archives and found some related info from Jeff Ballard: >Actually on Solaris 9 you want to put something like this in >/etc/system: > >set rlim_fd_cur = 32768 >set rlim_fd_max = 65536 > >That sets the current fd's to 32k and max to 64k. Unfortunately, to >take effect you'll need to reboot. After the reboot, ulimit -a should >show that nofiles(descriptors) is 32768. > >-Jeff And I found this from Jeff Earickson: >I ran into this problem with alpha4 on Solaris 9. I doubled the >following dovecot settings: > >login_max_processes_count = 256 (was 128) >login_max_logging_users = 512 (was 256) > >and the problem went away. I carried these numbers forward intoalpha5, >and it has been working fine. I changed my /etc/system file but have not rebooted yet. Also, on Jeff Earickson's post, I looked at my dovecot.conf settings and they're basically default which means everything in the "Login processes" section is commented out. I have 10 users on this system and will hold off migrating any more until I can resolve this problem. By the way, my "ulimit -a" shows "open files" at 256 which seems low. # ulimit -a core file size (blocks) 0 data seg size (kbytes) unlimited file size (blocks) unlimited open files 256 pipe size (512 bytes) 10 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 29995 virtual memory (kbytes) unlimited Any advice would be appreciated. I can't reboot for a few more days.

[Dovecot] 1.0 alpha5: Plugin woes: quota/trash
by Jan-Piet Mens 21 Dec '05

21 Dec '05

Hello, I'm running Dovecot v1.0.alpha5 and I'm trying to get the quota plugins to work. I've enabled modules in dovecot.conf, but when the IMAP connection is opened, the log shows undefined symbols. : Loading modules from directory: /usr/local/lib/dovecot/imap : dlopen(/usr/local/lib/dovecot/imap/libtrash_plugin.so) failed: /usr/local/lib/dovecot/imap/libtrash_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libimap_quota_plugin.so) failed: /usr/local/lib/dovecot/imap/libimap_quota_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libquota_plugin.so) failed: /usr/local/lib/dovecot/imap/libquota_plugin.so: undefined symbol: dict_transaction_commit The source shows that the modules are read by reading the module directory and loading each of the found .so files. Supposing that the ordering of the files in the directory is wrong, I've even recreated the module directory manually, copying the libs into it in different orders; no change. It seems to me as though there are cross-dependencies in the shared libs that cannot be resolved. Has anybody found it to work or could anyone give me a hint on how to get it working? Thanks & regards, -JP

I wrote a filesystem quota plugin for use with dovecot-0.99.x some time ago. It's been tested with both Solaris and FreeBSD, and is currently used on a production Solaris server with 20k users for exactly the purpose you describe - SquirrelMail quota display. If anyone's interested in looking at the code with an eye to extending OS support or accelerating conversion to the 1.0-alpha codebase, let me know and I'll get around to making it available somewhere. On the other hand, Timo made some noises about committing something similar to CVS, so it may be worth waiting. Robin

Hi, I would like to try implementing user specific default_mail_env's as described here: http://wiki.dovecot.org/moin.cgi/MailLocation using the LDAP attribute 'mailLocation'. However, I have been unable to find any LDAP schema which contains mailLocation. What schema is this attribute part of? Thanks, Jason Pepas

Hi! I world like to have different queries to let a user use pop only or imap only (webmail) accounts. It would really be very useful. I have not found any workaround get it working with dovecot. Could it be possible ? It should not be too difficult, I suppose. Max

[Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 20 Dec '05

20 Dec '05

Hi, I'm having trouble as of about noon today. I noticed I wasn't getting any new messages in Thunderbird. I restarted it and still nothing. I looked at the log, and found nothing from dovecot for a long time (since perhaps noon today). I restarted dovecot, but still it didn't get me new mail. I finally removed dovecot.* in my Maildir folder and restarted dovecot. I'm using 1.0alpha4. Now I'm still not able to get the new mail, and I get the following messages: Nov 20 20:49:59 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=plain, rip=172.17.128.191, lip=10.7.3.11 Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): Effective uid=501, gid=20 Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): maildir: data=/Users/frohro/Maildir Nov 20 20:49:59 cubex-wwc-edu dovecot: imap(frohro): maildir: root=/Users/frohro/Maildir, index=/Users/frohro/Maildir, control=, inbox= Nov 20 20:50:00 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2578 > 2566) Nov 20 20:50:00 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2578 > 2566) Nov 20 20:50:08 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:25 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=plain, rip=172.17.128.191, lip=10.7.3.11 Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Effective uid=501, gid=20 Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): maildir: data=/Users/frohro/Maildir Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): maildir: root=/Users/frohro/Maildir, index=/Users/frohro/Maildir, control=, inbox= Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:25 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) Nov 20 20:50:26 cubex-wwc-edu dovecot: imap(frohro): Corrupted index file /Users/frohro/Maildir/dovecot.index: messages_count too large (2588 > 2576) I guess I won't be able to read any answers to this in my mailbox, but I should be able to read the archive on the web.

[Dovecot] Auto-expunge
by John Newman 20 Dec '05

20 Dec '05

Hi, For some time we've been intermittently experiencing a problem whereby dovecot often automatically expunges "deleted" messages. This has happened across several mailboxes. The problem is proving difficult to isolate as it's seemingly non-deterministic in nature. One commonality, however, is that the "auto-expunge" seems to occur with greater frequency on mailboxes with a larger of deleted messages. First off, does this sound any alarm bells for anybody else? Perhaps others have encountered this in the past? I've trolled the mailing list (and web) but cannot find any references to this occurring elsewhere. Additional Information: We have experienced this "bug" in 1.0-alpha3 and alpha4. Underlying dovecot we have a maildir, populated via Perl's Mail::Box::Maildir module. Many thanks for any assistance that can be offered. John.
