We got a lot of false positives from exchange servers (which say helo with 
something like "mailgate1" or "mx-01" which is neither resolvable nor a 
FQDN). Its not a good idea to drop connection if the helo argument is not a 
FQDN. 

However dropping connections which sent the *own* relay name (i.e. the one 
where your mimedefang is running on) seems to work fine.
