I've setup a mail server using postfix + dovecot + vmm on postgres. But for some reason, my custom logcheck rules are getting ignored in some cases. As en example:

Feb 23 10:10:36 xxx dovecot: dict: pgsql(127.0.0.1): Connected to database mailsys

My logcheck-ignore rule looks like:

# Connecting to (vmm)-database
^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ dovecot: auth: pgsql\([[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\): Connected to database [[:alnum:]]+$

When I'm running

 logcheck-test -l /var/log/mail.info -r /etc/logcheck/ignore.d.server/local-dovecot-vmm 

the lines are getting printed out, so IMHO logcheck seems to find the lines with the ignore rule. But when running the cron again, it's not ignored. Any hint maybe?
