Another problem with BATV is that it will interfere with some mailing list 
posting, if that list restricts based on the sender, since the sender is 
rewritten with those BATV tags as part of the email address.  I know this is 
the case with ezmlm, for example.  I assume other lists are better at 
handling this, since I've never heard anyone complain about it with other 
types of lists before.
