dovecot - Apr 2007 - Maillog rotates, but dovecot still writes logs into old logfile?

Tere.


I use:

log_path = /var/log/maillog
info_log_path = /var/log/maillog

And into /var/log are:

maillog
maillog.1
maillog.2
maillog.3

Now when log files are rotating at 04:00 (maillog > maillog.1) dovecot 
still keeps login into maillog.1 and not into maillog, where sendmail, 
etc writes logs.

The only solution I did found, is adding into /etc/logrotate.d/syslog 
command to restart dovecot:

/var/log/maillog 
{

    
postrotate

    /usr/bin/killall -HUP 
syslogd

    /etc/rc.d/init.d/dovecot restart >/dev/null 
2>&1                                                              
    
endscript

}


Any other solution?

As per the wiki, dovecot listens to SIGUSR1 to reopen a log. You want to 
simply use a command like:

   /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> 
/dev/null || true

Could be dangerous, unless all programs writing to /var/log/maillog use
append mode (and it is on local disks, etc).

Yes, sounds right.

Have dovecot log via syslog instead of to a file, and the problem goes
away.

Prr, how did I miss this? So, uncommenting all:



#log_path = /var/log/maillog
#info_log_path = 
/var/log/maillog

#syslog_facility = mail   


should do the trick and log all via syslog to /var/log/maillog?
