[Dovecot] SquirrelMail IMAP protocol errors?
by Schettino, John Charles 08 May '05

08 May '05

I use Squirrelmail to filter messages, and it's doing this: raw log in: A009 UID SEARCH CHARSET ISO-8859-1 ALL Header X-Spam-Level {4} **** A010 LIST "" "spam" raw log out: * SEARCH A009 OK Search completed. * BAD Error in IMAP command : Unknown command. * LIST (\NoInferiors \Marked) "/" "spam" A010 OK List completed. it goes on like that in the log for every filter. What exactly is the BAD Error there, and is it something I can fix?

[Dovecot] Setting location for indexes
by dovecot.7.signal11＠spamgourmet.com 08 May '05

08 May '05

We have NFS-mounted user directories which cause significant problems with stale file handles: dovecot: IMAP(uid): fstat() failed with file /home/uid/mail/.imap/INBOX/dovecot.index.log: Stale NFS file handle (a) why can't it just close the file and re-open ? (b) is there a way to specify with the 'default_mail_env' (or in some other way) the location of **only** the indexes (and let dovecot autodetect all else?). I have already tried 'mmap_disable = yes', but that does not solve the problem, and if I set 'default_mail_env = INDEX=/var/spool/mail/INDEX/%u', I get errors like: IMAP(uid): Failed to create storage with data: INDEX=/var/spool/mail/INDEX/uid I don't want to specify mbox:~/mail/ or mbox:~/Mail/, because some users have one and some the other.

I'm using one of the stable 1.0 releases for 184 accounts on Gentoo Linux on Sparc. I too am seeing the message header/body mismatch in Thunderbird. Is the index file handling sufficiently robust against surprises that I can delete the dovecot index files every night out from under the logged-in imap sessions? Brian

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Help configuring dovecot for SSL
by Knute Johnson 04 May '05

04 May '05

Hi: I'm running dovecot on a Fedora 3 box and would like to be able to make a TLS connection to it with my Pegasus Mail program running on my Winblows machine. Does anybody know if it is possible? If it is I could really use some help configuring my dovecot. I have tried for several days but I really don't know what I'm doing and need a direction to start. Thanks, -- Knute Johnson Molon Labe...

[Dovecot] Multiple Logins - Single Mail Account
by Net Cerebrum 04 May '05

04 May '05

I have a mail account which needs to be accessed by 4-5 people simultaneously through IMAP. As of now I have configured it on the respective clients using the same username and password so we have multiple people accessing the same account through their mail clients simultaneously and it is working flawlessly. Is this alright or can it lead to some problems or corruption of data later ? What is the best way to allow multiple people to access a single mailbox for read as well as write operations ? Thanks,

[Dovecot] Error in rename uidlist while fetching through pop3
by James Berry 03 May '05

03 May '05

My dovecot server seems to randomly begin giving errors to pop3 users who try to fetch their email. Once this begins, they see no more new mail, though the mail is in cur. Running: dovecot-stable 20050501, Mac OS X 10.3.9 Log entries like this: May 2 19:35:18 caddy dovecot: pop3-login: Login: kim [24.22.16.169] May 2 19:35:18 caddy dovecot: POP3(kim): rename(/Users/kim/Maildir/ dovecot-uidlist.lock, /Users/kim/Maildir/dovecot-uidlist) failed: Input/output error May 2 19:35:18 caddy dovecot: POP3(kim): file_dotlock_replace(/Users/ kim/Maildir/dovecot-uidlist) failed: Input/output error Is this a known problem, and/or is there a known way to recover from such a situation? I'm managed to throw out the uidlist, but that means they get a whole dump of new mail. -jdb

[Dovecot] How to try dovecot-lda
by Joakim Verona 02 May '05

02 May '05

Hello, I'm interested in trying the dovecot-lda with sieve support. What would be the proper way to test it? I'm currently using a Fedore core 2 server, with spamassassin and procmail. To get the same effect with dovecot-lda, would I put a line like this in my .forward? spamassassin|dovecot-lda I'm just guessing, so please correct me if im wrong. Im thinking of setting up a separate mail account and copy my mail there to test the ported procmail to sieve recipies also. -- Joakim Verona www.verona.se

[Dovecot] disabling indexes?
by Marten Lehmann 02 May '05

02 May '05

Hello, I recently had the problem, that an index was corrupt. Thus, messages haven't been listed (talking about POP3), but still remained in the filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice that the index is corrupt and didn't rebuild it. The problem is, that a user can't delete messages through POP3 which aren't listed by dovecot. If the maildir size increases, the arrival of new messages will be blocked because the mailbox is full. And the user has no chance to delete it. Regards Marten
