No it doesn't.  Or at least not as meant by Brian.

The "Message|Block Sender" gets you an entry like 

   alan.is@a.coward.net

you'll still see posts with 'from' addresses as 

   alanis@acoward.net

It does not (for example) remove all posts with 
  news.dizum.com
in the path line or a
  X-Remailer-Contact: 
line in the headers.
