/var/virusmails expiry?

[@lbutlr]

The files in /var/virusmail appear to be expiring after 30 days, but I can’t find a setting in the amavisd.conf for that other than the $maxfiles setting. How can I set this to, for example, 7 days?

Or should I just setup a crontask for

find /var/virusmails/ -ctime +7 --delete?
