The logs stating the "File too large" errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets "File too large" error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag

[Dovecot] pam auth fail considered mail.error?
by David Halik 24 Nov '08

24 Nov '08

Hello all, Following the Dovecot wiki and migration help, we recently migrated our core IMAP systems from Courier to Dovecot on Solaris. So far it's been working great, but I have one issue that I'm curious about. Just as the docs mention, we also use "syslog_facility = mail" for logging. Unlike in the past, failed PAM auth attempts are now getting logged as mail.error: Nov 24 08:34:34 xxx.xxx.xxx.xxx dovecot: [ID 107833 mail.error] auth-worker(default): pam(dhalik,xxx.xxx.xxx.xxx): pam_authenticate() failed: Authentication failed Is there a reason for this, or a way to configure this behavior? mail.error is a little harsh for pam auth failures and I would think that the auth channel would be used instead similar to other processes (sshd, courier, etc) I'd like to continue using the mail facility, but if every time there is an auth error Dovecot reports to mail.error, my consoles and legitimate error logs are going to be full of something considered a non-issue by most. Any help is appreciated, thanks. -Dave -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] two dovecot server using the same file system
by Osvaldo Alvarez Pozo 24 Nov '08

24 Nov '08

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there a way of solving this issue?? Thanks

I manually deleted all the dovecot.index* files and the account started working. Perhaps dovecot could try the fix but if it still fails just go and delete the indexes itself?

Hi, Setting mailbox_size_limit to 0 made deliveries possible. a limit of 2000000000 (<2GB) also did not show the errors. Thank you ! :) My issue is fixed but deliver might have a bug, so I will explain things, sorry for not being clear previously. Old mail server was 32 bit(an old version of debian) and used procmail for deliveries, that setup worked with the given limit of 5GB and mailbox sizes above 1GB. After migrating to an 64 bit server (debian etch) and dovecot's deliver, the stated delivery errors appeared for mailboxes above 1 GB. As I stated at the beginning of my reply, setting mailbox_size_limit below 2GB made deliveries possible. I tried with edge values, mailbox_size_limit=2147483648 (exactly 2GB) would give the following error in postfix logs: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit A limit of 2147483648 - 1 worked fine. There are two distinct bugs probably, one in postfix and one in dovecot. I guess this is result of using integer values for size limit. values greater than 2GB would wrap and cause warnings in postfix. Probably, my previous limit of 5GB would confuse things and no error was reported. (I don't know how, 5GB cannot be stored in an unsigned int, double overrun makes it within limit ? :) ) Maybe moving to "long long int" for mailbox file size is a possible solution. -- Gokdeniz Karadag

[Dovecot] OT: Run Sieve On A Mailbox Manually
by Neil 22 Nov '08

22 Nov '08

(Apologies for being offtopic.) The subject basically says it all...does anyone know of a tool to run a sieve script on a mailbox (in particular, Maildirs) manually? Ideally, I'd like to do it without adding a bunch of new headers to the mail. So, could I just do a find (or for-loop, if it was just one maildir) command and pipe all the mails into deliver..? Thanks, Neil.

[Dovecot] mail_privileged_group not working for dotlock files (1.1.6)
by Rob Mangiafico 22 Nov '08

22 Nov '08

Hello, Running dovecot 1.1.6 on centOS 5 and RHEL 5. With the settings: pop3_lock_session = yes mail_privileged_group = mail mail_location = mbox:~/:INBOX=/var/spool/mail/%u mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl and /var/spool/mail permissions: drwxrwx--x 2 root mail 4096 Nov 19 10:16 mail/ Trying to connect via POP3 results in this error: --- Nov 19 09:31:01 lexiconn2 dovecot: child 32127 (pop3) killed with signal 11 Nov 19 09:31:01 lexiconn2 dovecot: POP3(cerberus): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Nov 19 09:31:01 lexiconn2 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=1.2.3.4, lip=5.6.7.8, secured --- The docs seem to indicate the above config / settings should work. Is this a bug? The reason we have dotlock as the primary format is due to procmail LDA from sendmail: --- procmail -v 2>&1|grep Locking Locking strategies: dotlocking, fcntl() --- I assume we have to make the "mbox_write_locks" match the procmail locking... Thanks. Rob
