Hi all, During the last days our local mailserver suddenly started to behave strangly, as incoming mails aren't delivered. Googling around the whole days unfortunately didn't lead to any solution. Any help from your side is appreciated! I have sent this mail to suse-imap-e@suse.com, too. People receiving it twice might discard on version, thanks! ;-) The configuration is quite simple: postfix -> cyrus. Used packages are postfix-2.0.6-14, cyrus-imapd-2.1.12-34, cyrus-sasl2-2.1.12-31, db-4.0.14-249 and the box is based on SuSE 8.2. As postfix and cyrus were started after executing the the backup script (like every night before), the next incoming mail was bounced due to relay while delivering to cyrus. Oct 26 02:17:01 mail postfix/pipe[23046]: 57230A800D: EB378A8011: to=<user@domain.de>, orig_to=<userorig@domain.de>, relay=cyrus, delay=1002, status=bounced (Command time limit exceeded: "/usr/lib/cyrus/bin/deliver") During the following days some mails were bounced, some others were queued but not bounced, and some others were delivered: Oct 28 02:33:25 mail postfix/pipe[449]: EA3D6A800E: to=<user@domain.de>, orig_to=user@domain.de>, relay=cyrus, delay=1998, status=sent (mail.domain.de) Restarting postfix, cyrus and saslauthd (and cleaning the queue manually by postqueue -f) temporarily fixed the problem, the delay decreased to a usual amount of 1 or 2 seconds. Nevertheless each restart of cyrus leaves the following logs in /var/log/warn: Oct 29 16:55:37 mail master[1718]: setrlimit: Unable to set file descriptors limit to -1: Operation not permitted Oct 29 16:55:37 mail master[1718]: retrying with 1024 (current max) Oct 29 16:55:49 mail tls_prune[2082]: DBERROR db4: 4 lockers In several postings this message were estimated to be of cosmetic character, is this right? Without any logical scheme the following entry as produced by cyrus: Oct 29 16:17:15 mail deliver[858]: connect(/var/lib/imap/socket/lmtp) failed: Connection refused This occurs both while booting the machine as starting cyrus manually, but I don't recognize any scheme. I thought about wrong permissions of /var/lib/imap/socket/lmtp, but they seem to be correct: mail:~ # ls -al /var/lib/imap/socket/ total 8 drwxr-xr-x 2 cyrus mail 4096 Oct 29 16:55 . drwxr-xr-x 12 cyrus mail 4096 Oct 29 20:25 .. -rw------- 1 cyrus mail 0 Oct 2 05:40 imap.lock srwxrwxrwx 1 root root 0 Oct 29 16:55 lmtp -rw------- 1 cyrus mail 0 Oct 2 06:59 lmtpunix.lock -rw------- 1 cyrus mail 0 Oct 4 02:16 sieve.lock mail:~ # ls -al /var/lib/imap/ total 84 drwxr-xr-x 12 cyrus mail 4096 Oct 29 20:25 . drwxr-xr-x 19 root root 4096 Oct 2 11:00 .. drwxr-x--- 2 cyrus mail 4096 Oct 29 16:55 db drwx------ 2 cyrus mail 4096 Oct 29 20:25 db.backup1 drwx------ 2 cyrus mail 4096 Oct 29 19:55 db.backup2 -rw------- 1 cyrus mail 24576 Oct 29 20:25 deliver.db drwxr-x--- 3 cyrus mail 4096 Oct 2 05:36 deliverdb drwxr-x--- 2 cyrus mail 4096 Mar 28 2003 log -rw------- 1 cyrus mail 3728 Oct 29 16:55 mailboxes.db drwxr-x--- 2 cyrus mail 4096 Mar 28 2003 msg drwxr-x--- 2 cyrus mail 4096 Oct 29 20:26 proc drwxr-x--- 28 cyrus mail 4096 Oct 2 05:36 quota drwxr-xr-x 2 cyrus mail 4096 Oct 29 16:55 socket -rw------- 1 cyrus mail 8192 Oct 29 16:55 tls_sessions.db drwxr-x--- 28 cyrus mail 4096 Oct 2 05:36 user Using a valid shell for user postfix I can even connect via lmtp: mail:~ # su - postfix -c "/usr/lib/cyrus/bin/deliver -l;" 220 mail LMTP Cyrus v2.1.12 ready Do you have any idea, why the transport of messages from postfix to cyrus is delayed and the incoming mails are bounced in consequence? As already mentioned this behaviour started without any changes to the configuration (running without problems before). See several configuration-files below.
