[Dovecot] post-login scripting using PHP
by Maciej Uhlig 26 Oct '10

26 Oct '10

I'd like to write post-login script using PHP. I noticed every shell post-login script ends with: exec "$@", which effectively executes dovecot's script-login. However, while I try to do the same (?) in PHP: $prog = $argv[1]; exec ("$prog"); it doesn't work. The client timeouts, dovecot (2.0.6) says "Disconnected for inactivity". May be I don't clearly see the way post-login scripting should work. Any hint to make it done? Regards, MU

[Dovecot] Exchange-replacement with SOGo
by Timo Sirainen 26 Oct '10

26 Oct '10

I thought some people here would be interested: Recently SOGo added support for OpenChange, which means Outlook can natively access it via MAPI the same way as Exchange. Everything is open source, and the great thing about SOGo is that it uses existing IMAP server for mails rather than reimplementing yet another one itself. They seem to prefer Cyrus, but apparently Dovecot should work too. For non-mail (calendar, etc) it uses SQL, but I heard it's not too difficult to replace that either if someone would prefer some NoSQL database or something. http://www.sogo.nu/ http://www.openchange.org/

[Dovecot] doveadm-expunge not expunging when ran from cron
by LEVAI Daniel 26 Oct '10

26 Oct '10

Hi! I noticed that this command ... : for USERNAME in ${USERS};do /usr/local/bin/doveadm -Dv expunge -u "${USERNAME}" mailbox sa.* SAVEDBEFORE 1d done ... does not expunge mails if ran from crontab. It shows in the Debug output what would have been done, but it doesn't really expunge those mails. This command runs daily, and every day the list of expunged mails (in the Debug output) just grows and grows, and the sa.* directories stay the same (except the new mails of course). However, if I run it from a terminal it really expunges the mails. Example output: doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6657 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6658 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6659 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6660 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6661 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6662 [...] If ran from cron, then the same uids show up every day, and new ones gets added (as new mails gets copied into those directories). Is there something fishy going on in doveadm-expunge if it has no controlling terminal?

[Dovecot] 2.0.2 : crashes with LDA
by Jakob Curdes 26 Oct '10

26 Oct '10

Hello, I just migrated to 2.0.2 and see some <xx(a)localhost.redirectme.net> (expanded from<xx@localhost>): Command died with signal 6: "/usr/local/libexec/dovecot/dovecot-lda -c /etc/dovecot2.conf". Command output: doveconf: Panic: file settings-parser.c: line 1838 (settings_copy_deflist_unique): assertion failed: (dest_count == ccount) doveconf: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0 [0x9395c0] -> /usr/local/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x45) [0x9396b5] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x938c78] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9183c7] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9182de] -> /usr/local/lib/dovecot/libdovecot.so.0(settings_parser_apply_changes+0x6f) [0x91849f] -> /usr/local/bin/doveconf(config_filter_parsers_get+0x25f) [0x804e8af] -> /usr/local/bin/doveconf(config_parse_file+0x6a8) [0x80502f8] -> /usr/local/bin/doveconf(main+0x21f) [0x804c43f] -> /lib/i686/nosegneg/libc.so.6(__libc_start_main+0xdc) [0x5c8e9c] -> /usr/local/bin/doveconf [0x804b291] This does not happen always; most mails get delivered normally through the LDA. A command line call of doveconf yields no problems. Any hints? Best regards, Jakob Curdes

[Dovecot] merge mdboxes
by Tobias Daucher 26 Oct '10

26 Oct '10

Hi there, after migration we have a very big problem... there are two mailboxes in /var/mail/username/mailboxes/ /var/mail/username/mailboxes/inbox /var/mail/username/mailboxes/inbox2 i DO have to merge these boxes, but i found no tools for this step. is there any way with doveadm oder dsync to move alle messages from mdbox inbox2 into mdbox inbox? i hope you all can tell me a way to do this - its a very very big problem at the moment. By the way - logging in via imap with thunderbird und move them on that way is not my favorite solution cause i have to do this for hundreds of users... i hope you can help me! thanks a lot!

I don't really know if there's much to do about this. I guess it could wait a second or so before disconnecting client to avoid it reconnecting back too fast.. > The client wasn't reconnecting as far as I can tell. It looked to me like the server process wedged after this error - we only got the error message logged once. The problem is that after it occurred no new clients could complete connections, but existing clients worked ok. Incoming connections were accepted, but then nothing would happen. As far as I can tell the parent would fork new child processes but they couldn't complete initialisation. Mail clients simply complained of a timeout during connection. This was affecting all users. With regard to error disconnections - yes a delay is a good idea.

[Dovecot] delivering mail to public mbox with permission 660?
by RParr 26 Oct '10

26 Oct '10

I am migrating a couple old RH servers running sendmail and UW-IMAP to a new Ubuntu 10.04 servers running Postfix and Dovecot. I have everything working reasonably well except that the permissions of newly created mbox mail folders is always 600. I have reviewed the archives, google, and double checked everything is as suggested in the Dovecot Wiki / SharedMailboxes / Permissions. I am running Ubuntu 10.04 packages postfix 2.7.0-1, dovecot-common, dovecot-imapd, dovecot-pop3d, and dovecot-postfix (all version 1.2.9-1ubuntu6.1). I plan to install amavisd-new, et.al. for spam filtering and anti-virus but have held off until I get Postfix and Dovecot working 100%. I have configured Postfix and Dovecot to use mbox mailboxes. I chose mbox becaus I have a LOT of shared mbox folders to migrate and decided it best to first migrate to Postfix/Dovecot mbox and later worry about migrating to maildir (as suggested on the Dovecot wiki mailbox format page). I have configured private (also as default) and public namespaces with the public mailboxes stored in /var/mail/public. /var/mail/public has rwxrws--- and is group tarts (the shared "company" group for this server). Initially I had procmail configured via the mailbox_command. Initial test mail sent to user tarts triggered creation of /var/mail/tarts with 660 permissions as expected. I then changed the configuration to use deliver via the mailbox_command. I did this because procmail appears to be unmaintained and to benefit from deliver's support for indexing at time of delivery and seive. I then added user testuser with primary group testuser and supplemental group tarts. I made sure testuser's home directory and mail sub dir had rwxrws--- permissions. I sent test mail to user testuser and had both user tarts and user testuser create some subfolders in public (via Thunderbird accounts) THE PROBLEM is that mbox folders that hold messages are created with permssion 600. My understanding, from the Dovecot wiki and other docs/postings is that the folders should be 660 given the /var/mail permssions of rwxrwsrwt and ~/mail permssions of rwxrws--- MY QUESTION is how do I correct the configuration and/or directory permissions so that mbox folders and .imap indices (especially public/ ones) are created with 660 permissions thus allowing users who belong to a common group (eg tarts) to access the public mailboxes? It appears all Dovecot configuration options to establish directory/box perms or mask, such as umask, have been deprectated and no longer work. The primary option appears to be using the permissions yet that is not working for me here. ----------------------------------- /home/: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:59 tarts/ /home/tarts: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:50 mail/ ----------------------------------- /d/home/: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 testuser/ /d/home/testuser: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 mail/ /d/home/testuser/mail: total 20 drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:44 ../ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 .imap/ -rw-rw---- 1 testuser testuser 36 2010-10-19 13:59 .subscriptions -rw------- 1 testuser testuser 0 2010-10-19 13:50 Trash drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 test1/ -rw------- 1 testuser testuser 0 2010-10-19 13:54 test2 /d/home/testuser/mail/.imap: total 12 drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 INBOX/ /d/home/testuser/mail/.imap/INBOX: total 24 drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ../ -rw------- 1 testuser testuser 16384 2010-10-19 14:00 dovecot.index.cache -rw------- 1 testuser testuser 864 2010-10-19 14:00 dovecot.index.log /d/home/testuser/mail/test1: total 8 drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ -rw------- 1 testuser testuser 0 2010-10-19 13:54 sub1 ----------------------------------- /var: drwsrwsrwt 3 root mail 4096 2010-10-18 10:23 mail/ /var/mail: total 896 drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ./ drwxr-xr-x 16 root root 4096 2010-03-05 13:57 ../ -rw-rw---- 1 nobody mail 1386 2010-10-12 16:54 nobody drwsrws--- 5 root tarts 4096 2010-10-19 13:51 public/ -rw-rw---- 1 tarts mail 894107 2010-10-19 08:59 tarts -rw------- 1 testuser mail 632 2010-10-19 13:51 testuser /var/mail/public: total 24 drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ./ drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 .imap/ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 test1/ drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 test2/ -rw------- 1 testuser tarts 633 2010-10-19 13:51 test3 /var/mail/public/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 test3/ /var/mail/public/.imap/test3: total 28 drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 ./ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ../ -rw------- 1 testuser tarts 16384 2010-10-19 13:51 dovecot.index.cache -rw------- 1 testuser tarts 628 2010-10-19 13:51 dovecot.index.log /var/mail/public/test1: total 16 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 .imap/ -rw------- 1 tarts tarts 614 2010-10-16 15:02 sub1 -rw------- 1 tarts tarts 0 2010-10-16 15:01 sub2 /var/mail/public/test1/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 sub1/ /var/mail/public/test1/.imap/sub1: total 12 drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ -rw------- 1 tarts tarts 408 2010-10-16 15:02 dovecot.index.log /var/mail/public/test2: total 8 drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ Any help would be greatly appreciated.
