Debian logcheck ignore file for sSMTP

On a server, I use logcheck to get an email based on logfile analysis if anything goes wrong and doesn’t fit the usual patterns. In addition, I use sSMTP to forward all sent mails to my mailserver. Unfortunately, this solution ends up in sending a mail like the following every hour because of a bug in logcheck’s ignorefile for sSMTP.

Dec 12 22:02:06 hostname sSMTP[22391]: Sent mail for logcheck@hostname (221 2.0.0 Bye) uid=101 username=logcheck outbytes=639

To fix this, I replaced the contents of the file /etc/logcheck/ignore.d.server/ssmtp with the following lines:

^w{3} [0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2} [a-zA-Z0-9]+ sSMTP[[0-9]+]: Sent mail for logcheck@.*$
^w{3}  [0-9] [0-9]{2}:[0-9]{2}:[0-9]{2} [a-zA-Z0-9]+ sSMTP[[0-9]+]: Sent mail for logcheck@.*$

I removed the other lines, because sSMTP shouldn’t do anything else on the system and if it would, I’d like to be informed. If you need more ignore patterns you might have to keep/edit some of the original lines.
