Add support for only ProSpamFilter debug logging with log rotation

[ashleyse2016]

Often its good to have the debug logging on however as this is a very verbose type of log, its not viable to keep running a long time. This is specially relevant when you are looking for hard to trigger issues.

It would be great if there was a way to simply enable "logging" of the addon, and this logged only the "ProSpamFilter" logging (and not every thing else found in /var/log/debug), and was able to then log-rotate the files every day. (with a possible expiry). This way, logging can be enabled for multiple days/week.

Looks like you can actually already set this to rotate

1: type touch /etc/prospamfilter/debug
2: add the following to rsyslog.conf

##SpamExperts debug logging##
*.debug                         /usr/local/cpanel/logs/ProSpam.log

3: type /etc/init.d/rsyslog restart
4: Go to Home »Service Configuration »cPanel Log Rotation Configuration in WHM
5: Tick ProSpam.log
6: Click Save

This doesn't extract only the ProSpamFilter lines, but likely thats possible with Property-based filtering with rsyslog. Will update here when i find it.

seems this is possible in the rsyslog.conf file instead

##SpamExperts test debug logging##
:programname, contains, "ProSpamFilter" /usr/local/cpanel/logs/ProSpam.log

So same steps above to log rotate it.
