This also applies to the thread "simple procmail recipe".

Have you guys tried spamassin?  Judging whether a message is spam or not, just 
by where it comes from seems quite discriminatory, where as judging it based 
on the content of the message makes much more sense to me.

If your clients businesses, or worse, your own, are at all dealing 
internationally, then I'd seriously reconsider the practice of blocking such 
large parts of the internet.

Australia has recently passed anti spam legislation which prohibits the 
sending of spam etc. (Even advertisement SMS messages, which do get annoying)   
There's more detail I won't go in to.

Also, consider subscribing to one of the black lists, RBL etc.  exim and other 
MTA's interface quite easily with all of these anti-spam solutions.
