The first thing you should consider, if you have control over the DNS
for cpurn.net, is to publish an SPF record for your domain. It will
cut down on the size of the problem somewhat.
See http://www.openspf.org/
If by somewhat you mean by one or two emails a day, you are correct.
The admins running accept and bounce later servers are clueless and have
probably never even heard of SPF.
I'll just let you know that I know this for a fact because my personal
domain was used about 6 month's ago by some spammer and I was getting
millions of bounce backs a day (at the peak there were 500K an hour). I
finally had to just shut the domain down for 2 months or so until it
abated. It had SPF records from day one, with a hard fail.
Good luck Christian, if you want some regex's to use to reject mail
bounces I have a whack of them for use with qmail/simscan but they
should be easily adaptable to other setups.

Rick
