[Dovecot] system & virtual setup
by Jim Pazarena 07 Mar '09

07 Mar '09

No one replied to my original email, and I was hoping if I re-phrase my question I can get an answer. I would like dovecot to provide system email (located at /mail/%u with system password and /home/%u) and also virtual email (/u/mail/VIRTUAL/%d/%u with password found at /u/exim/etc/VIRTUAL/%d/passwd). NO home space, but I would consider /home/%d/%u This I think has something to do with namespace, but the docs are too vague for me to understand. Can anyone help me out? I would very much appreciate it. I would even consider PAYING someone to set me straight. I am looking to migrate away from vm-pop3d. initially with POP3 and ultimately into IMAP. Thanks!

[Dovecot] [patch] example configuration for expire seems broken
by Robert McQueen 06 Mar '09

06 Mar '09

The expire configuration in the example config file in 1.1.11 is broken: root@omega:/etc/dovecot# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecot Unknown dict module: db expire plugin: dict_init() failed Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! It's inconsistent with the documentation at http://wiki.dovecot.org/Plugins/Expire, so I've made the attached patch to try and fix it. Note: I don't know if this new configuration is correct either, because its a new box and I've not got any mails old enough to cause the plugin to try and write anything, but at least I can start dovecot like this. :) Regards, Rob

[Dovecot] verbose_proctitle doesn't work?
by Mark Hedges 05 Mar '09

05 Mar '09

How is verbose_proctitle supposed to work? I set it in the config but I don't see anything particularly verbose while the mailbox is connected. This is while the connection is open, immediately after deleting a message, before closing the connection. Same for IMAP and POP tests. # `ps axu | grep dove` # root 20392 0.0 0.0 1888 540 ? Ss 12:45 0:00 /usr/sbin/dovecot # root 20393 0.0 0.0 8112 1968 ? S 12:45 0:00 dovecot-auth # root 20395 0.0 0.0 8116 2048 ? S 12:45 0:00 dovecot-auth -w # dovecot 20396 0.0 0.0 4828 1520 ? S 12:45 0:00 pop3-login # dovecot 20400 0.0 0.0 4832 1528 ? S 12:45 0:00 imap-login # dovecot 20401 0.0 0.0 4836 1528 ? S 12:45 0:00 imap-login # dovecot 20533 0.0 0.0 4824 1808 ?

S 13:07 0:00 imap-login I think I don't need this anymore but it would be useful. Mark

[Dovecot] imap locking spool?
by Mark Hedges 05 Mar '09

05 Mar '09

How does IMAP lock the /var/spool/mail/user file? Here's my problem: I'm writing a script to expire old or oversize mail through a series of archive folders. I don't want to take the whole server down to do this, nor does it seem like I would have to lock the user out entirely if I can manage to emulate the locks correctly. I am able to lock /var/spool/mail/user (and ~user/mail/*) from procmail, dovecot popmail, and openwebmail using dotlocks. What do I do to prevent dovecot imap from writing the spool and various mbox files while my script is running? Just posix fcntl on the various files? I'm trying to use Mail::Box in perl which I'm having some problems with, corresponding with the developer, but if anyone has any easy way out I would appreciate the advice very much! Mark

[Dovecot] failed assertion in 1.1.8: istream.c: line 81
by Alan Ferrency 05 Mar '09

05 Mar '09

Hello, We're having a problem in Dovecot 1.1.8 with a failed assertion on certain mbox format mailboxes. It happens both with deliver when it attempts to delier to the mailbox, and with IMAP connections for the affected box (though I'm not sure what they're doing at the time). Mar 3 12:55:26 <snip> dovecot: Panic: IMAP(<snip>): file istream.c: line 81 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) This is on FreeBSD 6.2, without any nfs. The IMAP client is Squirrel Mail, but as I said, the assertion occurs with deliver as well. Apparently, moving the inbox out of the way fixed the problem for a while, but then it came back. Clearing out the dovecot index files seemed not to have any effect. I have a core dump available for deliver; here's a backtrace: #0 0x282bbecb in kill () from /lib/libc.so.6 #1 0x282bbe68 in raise () from /lib/libc.so.6 #2 0x282bab78 in abort () from /lib/libc.so.6 #3 0x080b7ad8 in default_fatal_finish (type=LOG_TYPE_PANIC, status=0) at failures.c:150 #4 0x080b7dbb in i_syslog_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)", args=0xbfbfe2a4 "{\215\r\bQ") at failures.c:308 #5 0x080b7c37 in i_panic (format=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)") at failures.c:197 #6 0x080bb8a1 in i_stream_read (stream=0x8102e28) at istream.c:93 #7 0x080bbd3d in i_stream_read_data (stream=0x8102e28, data_r=0xbfbfe350, size_r=0xbfbfe354, threshold=0) at istream.c:322 #8 0x0806d85b in istream_raw_mbox_get_body_size (stream=0x8102e28, expected_body_size=11013) at istream-raw-mbox.c:562 #9 0x080736dd in mbox_sync_do (sync_ctx=0xbfbfe640, flags=0) at mbox-sync.c:151 #10 0x08075700 in mbox_sync (mbox=0x8103028, flags=0) at mbox-sync.c:1833 #11 0x08070001 in mbox_save_init (_t=0x80f2980, flags=0, keywords=0x0, received_date=1236108538, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0x0) at mbox-save.c:318 #12 0x282ee17f in quota_save_init (t=0x80f2980, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at quota-storage.c:236 #13 0x0808e36d in mailbox_save_init (t=0x5, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at mail-storage.c:726 #14 0x0808c34a in mail_storage_copy (t=0x80f2980, mail=0xbfbfe9f0, flags=0, keywords=0x0, dest_mail=0x8106028) at mail-copy.c:28 #15 0x282ee08a in quota_copy (t=0x80f2980, mail=0x80fd028, flags=0, keywords=0x0, dest_mail=0x8106028) at quota-storage.c:180 #16 0x080590a4 in deliver_save (namespaces=0x80f7028, storage_r=0xbfbfeb60, mailbox=0x80d0eeb "INBOX", mail=0x80fd028, flags=0, keywords=0x0) at deliver.c:237 #17 0x0805a90c in main (argc=5, argv=0xbfbfec14) at deliver.c:1093 Does anyone have any clues on how to debug this further? I wonder if the original bug reporter removed both the mailbox and the index files at the same time; the current explanation is less than satisfactory. Thanks, Alan Ferrency pair Networks, Inc.

[Dovecot] deliver to root
by Philipp Kolmann 05 Mar '09

05 Mar '09

Hi, we use dovecot 1.1.11 on a RH Server with sendmail. Local delivery is done with deliver: Mlocal, P=/usr/local/libexec/dovecot/deliver, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=deliver -d $u This setup works without issues for us, but mail to root has a problem with deliver: deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as uid deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as gid deliver(root): Mar 04 16:31:31 Error: User root is missing UID (set mail_uid) Is it generally not possible to use deliver to deliver mail to root? Thanks Philipp

[Dovecot] Outlook cant delete folders

Hello, It has been brought to my attention that outlook users cant delete folders from their mailbox. They can move them around and erase emails, but when it comes to folders, they cant..
