I use an external spam filter (Securence) to block spam into my business.
It works great, is cost effective and easy to manage.

But... While reading my daily reports I have been noticing that >99% of the
email that hits securence is spam or viruses or some other flavor of carp.
Once my domain name is harvested, all manner of trash comes in to Securence
garbage.bucket@name.com will deliver mail.

That means that every day, my work load to fish the odd good message out of
Securence goes up. The processing time to go through my ISP then
Securence, then to my server and then to the employees Outlook increases.
Day by day, week by week and year by year it slowly but surely is grinding
to a halt.

There has to be a way to deal with this problem.
