Dual Daemon Postfix log rotate

With dual daemons Posftix, you might want to separate the log file for each daemon.

Let's say the 1st daemon logs to /var/log/maillog and the 2nd daemon logs to /var/log/maillog2, and you want to rotate the log files. I encountered issue when tried to rotate the second log file because maybe the pid of the daemons.

Anyway, I created the second logrotate file /etc/logrotate.d/maillog2 with the following content:

/var/log/maillog2
{
notifempty
daily
rotate 7
compress
postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null true
/etc/init.d/postfix reload > /dev/null
/etc/init.d/postfix2 reload > /dev/null
endscript
}
