The following link describes a problem we are experiencing:
http://www.joewein.net/blog/2009/01/21/google-groups-spam-abuse-reporting-broken/
It seems to me the only way to counter that type of spam is to
do a curl or wget on each url in a message an submit the content
thereof to Spamassassin. But you can't do that on 200000 emails per
day and I am not sure how to handle such a process from exim.
I am sure I am not the only one having to deal with this kind of
spam. How do you counter it?
Regards
Johann
