Not really.  I have some RBLs listed in postfix which block it before 
it's saved on my computer.  This returns an error 554 before the 
message is completely delivered.

spamassassin is *better* than sliced bread.  In the typical week it 
blocks about 200 out of 201 spams, and I haven't encountered a false 
positive yet.

When you set up procmail right, spamassassin-detected messages will 
appear to bounce from MAILER-DAEMON with the "user unknown" error.

Let me know if you'd like a copy of my config files.
