Yeah, I'd go along with that. It has bayesianesque spam filtering. The  
only annoying thing I find is that it doesn't have a button or a  
keyboard shortcut to 'previous/next message'. It's beautifully  
AppleScriptable too, as you see from my sig.

There's also Thunderbird of course...

Both of these can use scoring put in mail headers by say SpamAssassin  
as part of their Spam detection.

As a client? Or running as a server? (I used to run  
fetchmail/SpamAssassin/UWash IMAP locally to get and spamcheck mail  
from an external pop server)

Generally, I'd caution against heuristic methods - you're then manually  
taking part in an arms race. Statistical methods are less work and give  
very very good results.
