On that run I had 62 messages on the server. After mailfilter did its
thing, fetchmail downloaded 40 messages. Of those 40 2 were spam cought
by SA and they were added to the mailfilter rules, so I won't see them
again.
I guess you could use fetchmail to weed them out but I found that
spending time on the DENY rules in mailfilter was better spent.
Rather then reinvent the wheel, I installed mailfilter.
