milter-null is a bit smarter than just discading them all, it tags mail that 
flows out of my mailservers with X-Null-Tag in the header, this then gets 
checked on any bounces that include enough of the header to find it, if they 
do then the bounce gets let in.

Downsides to milter-null IMO
1)Its not foolproof as some bounces still dont include the full header - but 
when you get 1000's a day its less of a concern
2)You do need sendmail though or postfix I think
3)All outbound mail needs to be tagged if you want to see legit bounces
4)It phones home which some might not like it
5+)Stuff I've forgot

If the day had more hours I'd be tempted to code something up to see how 
many people could see how to ack a C/R sent this way. It wouldn't be the 
ideal answer but better than the current bunch (unless I've missed an 
implementation that does this and also straight out rejects any mail that 
fails SPF).
