I have a mailing server setup based on Debian Stable that uses postfix
(v3.7.10) for SMTP and dovecot (v2.3.19.1 (9b53102964)) for IMAP. I now
wanted to set dovecot to not write to syslog, but to dedicated files in
/var/log/dovecot. While everything indicates that this happens
successfully as the log files gain in size, I also get lots of these
errors:
May 13 20:55:37 mail postfix/local[2824184]: 95BCF1000A9:
to=<u...@domain.de>, relay=local, delay=3.2, delays=1.9/0.29/0/1.1,
dsn=4.3.0, status=deferred (temporary failure. Command output:
lda(user): Error: net_connect_unix(/run/dovecot/stats-writer) failed:
Permission denied Can't open log file /var/log/dovecot/error.log:
Permission denied )
If it would only log the complaints I wouldn't worry, but as long as I
don't revert the changes in dovecot's config, mail receiving is at least
vastly delayed, most likely stuck alltogether. So how am I supposed to
set these settings?
I've chainged these settings in /etc/dovecot/conf.d/10-logging.conf:
log_path = /var/log/dovecot/error.log
debug_log_path = /var/log/dovecot/debug.log
log_debug = category=error
The whole directory /var/log/dovecot is owned by dovecot:dovecot,
permissions on debug.log, error.log and info.log are 644.
Check the permissions of the entire path, as dovecot:
namei -l /var/log/dovecot/error.log
It might be selinux, check your audit.log file, or set selinux to
permissive mode and see if it works:
setenforce 0
It might also be apparmour (sorry don't have instructions for apparmour).
The message basically means that something is preventing the dovecot
user from writing to the file, you need to figure out what that is.
