[Dovecot] Dovecot don't recognise new messages in maildir /new
by Tim Wagner 27 Jan '06

27 Jan '06

Hi, i'm google for it and i searched the archives, but i can't find the problem i have or a hint for a solution. I'm using Postfix as MTA, the new messages deliver by postfix to the maildir: /mail/domain.tld/userpart/new/ Dovecot sometimes show the new mails directly (it's very unusual) but mostly it needs for an hour that dovecot recognize the new messages. Reconnecting of the client don't help. Tested with Thunderbird, Sylpheed-Claws, mutt and muttng. Is there a bug known or do i something wrong?

[Dovecot] Fwd: Weird problem opening mbox in beta1/2
by Chris Wakelin 27 Jan '06

27 Jan '06

Hmm, this is peculiar! This mailbox has been unchanged on my test server since September. I've been using it to test each new version of Dovecot just after I've compiled it. When beta1 was released, I opened this mbox with no problems. However, when I upgraded to beta2, I got "file size unexpectedly shrinked in mbox file /export/mail/a/24/vis99003/INBOX (16895967 vs 16899267)". Reverting to beta1, it also failed with the same error! I've deleted indexes, restored the mbox from a backup made in October (no changes) and I still get the error. It *does* open OK in 1.0-stable. I've put it through mboxcrypt.pl, deleted the UW-IMAP pseudo-message (which wasn't converted properly by mboxcrypt) and it still fails to open with a similar error, so I've sent it to Timo (gzipped, of course!) I've e-mailed this to the list minus the attachment as sending unsolicited 1MB attachments is unfriendly! However, if anybody wants to look at it, please let me know. Best Wishes, Chris P.S. The past participle of "shrink" is "shrunk" not "shrinked" - it's yet another irregular English verb :) -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094 -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094

[Dovecot] Hang in 1.0.alpha4
by Mark Plaksin 26 Jan '06

26 Jan '06

My IMAP client hangs intermittently. When it does, Dovecot has prematurely stopped sending a response and entered the poll loop. My client is waiting for more data and Dovecot is waiting for an IMAP command. This problem seems to occur when I connect to the dovecot process over the network and when I run the imap binary directly via an SSH tunnel. Below is truss output from the imap process for one of the hangs. It is responding to a FETCH, gets EAGAIN, and then seems to give up sending the rest of the message and enters the poll loop. Below that is the log from my IMAP client to show its side of the story. Nothing shows up in the normal Dovecot log. I haven't caught it in the act recently when running with rawlog. But rawlog output from before I was running with truss shows that Dovecot does not think it has finished sending its response. truss output: 12951: stat64("/home/happy/Mail/banner-ss", 0xFFBFF200) = 0 12951: fstat64(12, 0xFFBFF388) = 0 12951: stat64("/home/happy/Mail/.imap/banner-ss/dovecot.index", 0xFFBFF2F0) = 0 12951: fstat64(18, 0xFFBFF388) = 0 12951: pread64(18, "\n F r o m b e v e r l".., 4096, 1592560) = 4096 12951: pread64(18, " S u n G a r d * S C".., 4094, 1596656) = 4094 12951: pread64(18, " M i c r o s o f t S a".., 4094, 1600750) = 4094 12951: pread64(18, " r g a r e t . d i l l a".., 4094, 1604844) = 3720 12951: pread64(18, 0x0025EEA2, 374, 1608564) = 0 12951: pread64(18, 0x0025EEA2, 374, 1608564) = 0 12951: pread64(18, " R e t u r n - P a t h :".., 4096, 1592616) = 4096 12951: write(1, " * 2 5 0 F E T C H ".., 4073) = 4073 12951: pread64(18, " a l v e r n , P A ".., 4095, 1596712) = 4095 12951: write(1, "\n W i l l i a m B .

by Jeff A. Earickson 26 Jan '06

26 Jan '06

Hi, I just discovered a whole lot of dovecot.index.log.2 files in people's .imap folders? Are these files needed in the long term? Or can they be zapped if they are more than X days old? Jeff Earickson Colby College

[Dovecot] dovecot 1.0alpha5 not deleting messages from mbox
by Andrew Mendelsohn 26 Jan '06

26 Jan '06

Hi, I have had some problem with duplicate emails using dovecot1.0alpha5using the prebuilt testing binaries on a debian stable/testing 3.1system. I am running both pop3d and imap, but all users are just usingpop3d. I am using mbox format. Users are using Thunderbird 1.5 to access emails. Dotlocks are used,postfix is the email agent. Note that dovecot/[postfix are running in avserver. In debugging the dovecot log, it seems to me that dovecot thinks thatit is deleting the messages, but actually nothing is happening. here is a log of a user logging in and what happens after logging out: dovecot: 2006-01-20 21:41:04 Info: pop3-login: Login:user=<user2(a)example.org>, method=PLAIN, rip=10.8.0.6,lip=192.168.99.5, TLS dovecot: 2006-01-20 21:41:04 Error: pop3(user2(a)example.org): mbox sync:Expunged message reappeared in mailbox /home/vmail/user2(a)example.org(UID 5668 < 5691, seq=2, idx_msgs=0) dovecot: 2006-01-20 21:45:33 Info: pop3(user2(a)example.org): Logout.top=0/0, retr=20/ del=20/20, size=29362389 a quick check show that mbox size has not been changed -- none of the20/20 files have been deleted, even though dovecot states del=20/20 ! Mboxes grow quite large, sometime the problem resolves itself. Interestingly, if I stop dovecot and restart it, on the next access to pop3 all of the messages are deleted correctly and the mboxreturns to the default size. Any ideas?

[Dovecot] Dovecot using static uid gid
by Alexandru Ionescu 26 Jan '06

26 Jan '06

Hi All I have postfix deliver the mail in virtual maildirs using the UID of user dovecot. I authenticate users trying to access their mailboxes via IMAP through winbind. The authentication is successfull but dovecot logs imap(username): Date "Error: openidir (vmail/domain/username) failed: Permission denied. I tried to insert in dovecot.conf: static uid=97 gid=97 home=/vmail/domain but I get a report that parameters are missing. Does anybody know the the exact syntax for the static directive? Alexandru

[Dovecot] Making dovecot and postfix play together
by Anne Wilson 26 Jan '06

26 Jan '06

I am encountering 'transport problems' in postfix, and I can't tie them down. I'm beginning to wonder whether I have conflicting settings in the various parts of the mail server. I have been advised separately by a number of people, so it is entirely possible. I am, therefore, attempting to check every detail of my setup. I was advised to put 'MAIL=/home/$USER/MailDir:INBOX=/var/spool/mail/$USER' into /etc/profile 'because that's the way that dovecot likes it'. Is this correct? I'm using 0.99.14 on Fedora Core 4. Dovecot does appear to be working correctly. I can drag messages to the mailboxes. The problem appears to be in postfix. Fetchmail can download the messages, but they are sticking in postfix's queue. I'm still working on that, but would like confirmation that I was right to follow the advice given above. Anne
