[Dovecot] Expunge is not expunging unless it is called twice
by Bill Boebel 03 May '06

03 May '06

Dovecot is requiring two "expunge" calls before it deletes an email. It just seems to ignore the first expunge call, leaving the email file in the maildir cur/ folder. Any idea why? I even waited 10 seconds after setting the Deleted flag, but still the first expunge call did nothing.... 1 OK User logged in 2 select "INBOX" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 12 EXISTS * 0 RECENT * OK [UIDVALIDITY 1144082550] UIDs valid * OK [UIDNEXT 1509] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID STORE 1511 +FLAGS (\Deleted) * 12 FETCH (UID 1508 FLAGS (\Deleted \Seen)) 3 OK Store completed. 4 expunge 4 OK Expunge completed. 5 expunge * 12 EXPUNGE 5 OK Expunge completed.

[Dovecot] errors while testing with imaptest
by Jens Laas 03 May '06

03 May '06

I get lots of these (in error log): dovecot: Apr 28 14:50:03 Error: IMAP(jenslt): Corrupted index cache file /home0/jenslt/.imap/INBOX/dovecot.index.cache: record points outside file And some of these: dovecot: Apr 28 14:50:03 Error: IMAP(jenslt): Corrupted index cache file /home0/jenslt/.imap/INBOX/dovecot.index.cache: field index too large (2037149797 >= 19) Should I worry or not? (Assuming its not due to me having broken imaptest). This was with command: imaptest jenslt@xxxx:yyy pass=xxxx clients=40 msgs=300 Local software raid 5 on linux 2.6.16.11 on reiserfs.

[Dovecot] Dovecot LDA - Performance/issues versus postfix delivery? Also, installing on OS X?
by Dean Blackburn 03 May '06

03 May '06

Can anyone give me an idea of whether or not dovecot-lda can solve the following issue: We seem to have constantly-corrupting dovecot* files for people who fit one (or more) of the following categories: 1) 1000+ message inboxes; 2) multiple clients simultaneously checking mail; 3) people receiving a lot of mail, and/or the server receiving and trying to deliver a single message to all users at once We're using straight postfix maildir delivery, and while the mail keeps coming, we start to see a lot of "temp.xxxx.xxxx.xxx" type lockfiles build up after any inconsistencies appear in the Inbox indexes, and clients start to report timeouts and/or crash as a result. Would switching to LDA by itself resolve this issue (on the argument that delivery would ALSO update the indexes every time), or is there some more fundamental issue we are having that is causing the inconsistency to arise? On a related note: I noticed the darwinports version of 1.0beta7 does not include the code for dovecot-lda... Does anyone have experience setting this up? Thanks! -deano

[Dovecot] madvise() errors
by Mark E. Mallett 02 May '06

02 May '06

(I think this has been mentioned before.) Do these hurt?: May 2 13:41:30 sysname dovecot: POP3(xxxx): madvise() failed with file /users/xx/xxxx/Maildir/dovecot.index.log: Operation not supported I think not, since I've been seeing them forever. But they do muddy the logs. This is on an old BSD/OS server, where the man page for madvise ends with: BUGS This call is not yet supported. The messages are *only* about index.log files. Would it be possible to either suppress the log message if the error is specifically "not supported" or, better yet, detect it at configure time? Completely understandable if it's not worth the effort, though. mm

[Dovecot] create_dovecot_shares
by Gavin Henry 02 May '06

02 May '06

Dear All, We've been working on this for a client to help create and manage maildir shares, via the dovecot-shared file. Our problems are creating lots of dovecot-shared files and permissions and monitoring new Maildir folders that get added by the user (maybe a better way, would love to know). The tool is almost done, with the docs at: http://www.suretecsystems.com/our_docs/create_dovecot_shares.html Maybe this can be of use to others when it's finished. Thanks, Gavin. P.S> Might be redundant a little when the ACLs are complete, as per Timos' e-mail earlier today: http://dovecot.org/pipermail/dovecot/2006-May/012991.html -- Kind Regards, Gavin Henry.

[Dovecot] Assertion failed
by Jonathan Knight 02 May '06

02 May '06

We're in a bit of a panic here as we're getting a lot of errors along the lines of: May 2 12:39:00 lenny dovecot: IMAP(XXXXX): file mbox-sync-rewrite.c: line 106 (mbox_sync_headers_add_space): assertion failed: (start_pos < data_size) We didn't see this until our mail servers went under a full load and now we've trashed the ability of nearly all our users to read email. We saw this first under 1.0Beta3 and we've tried building 1.0Beta7 and its made no difference. I've tried fiddling with the "dirty" settings for the indices and banning mmap to see if there's any way way of avoiding the broken code, but with no luck. We're running White Box EL4 (2.6 Linux kernel) Does anyone know a workaround or whether there is an older version that doesn't have the bug? We desperately need to get an email service running and I don't want to go back to (shudder) UW-imap if I can help it but my options are limited at the moment. -- ______ J.Knight(a)kis.keele.ac.uk Jonathan Knight, / Keele Information Services / _ __ Telephone: +44 1782 583478 University of Keele, Keele, (_/ (_) / / Fax : +44 1782 713082 Staffordshire.

[Dovecot] Dovecot and NFS with file locking
by Nate Sanders 02 May '06

02 May '06

Greetings all, I'm trying to get an understanding of a problem we are facing here. We're currently running dovecot 1.0-beta3 and have a long standing issue of system crashes on our mail server (Debian Linux 2.4.27-2-k7-smp). Here's what is happening: The machine hangs and the system load climbs as high as 80.0+. Yet, the system response is not effected. Command line is still responds instantly. There are multiple running dovecot PIDs, even if I stop the service. If I try to kill or -9 the PIDs, they will not die. The machine is DOA and must be forcefully restarted. Issuing a reboot will cause the machine to hang when it attempts to unmount network shares. Here's the setup: - Dovecot 1.0-beta3 - lock_method = dotlock - mmap_disable = yes /var/mail is store locally on the mail server and access via NFS to ALL remote machines. All remote machines have /var/mail sym linked to the NFS share on Mail. /home on Mail is NFS'd to another set of servers where IMAP mail folders reside in mbox format. All client machines have /home sym linked to the second NFS server. In other words, there's a lot of NFS shares and one mail transaction can involve 3 machines. What I'm trying to find out is the current state of NFS locking with Dovecot. This system hang happens 1-3 times a week. The current /home NFS mounts are running from SGI machines on IRIX 6.5. Clients are all Linux (debian) 2.4 or Linux (ubuntu) 2.6. Is our setup too much for Dovecot to handle? Are there other variables we're not looking at here?

[Dovecot] blank forwarded messages
by lenny＠edpausa.com 02 May '06

02 May '06

Just switched from uw to dovecot ( latest beta3 + lda ) on production system and everything seems fine except... There's some strange problem with forwarding messages from thundebird, the body of the forwarded message is always completely blank - 0 byte size. Forwarding from squrrel, horde, eudora and outlook works fine. Client setup on thunderbird installs hasn't changed a bit. I'm still investigating why this is happening. Has anyone run into this ?
