>Isn't an UNKNOWN account a Bad Idea?

It can be, as it opens you to dictionary spam attacks and the likes. It 
also defeats some of the spam trap features (such as temp banning for 
hitting to many invalid addresses).

I use the unknown for one of my servers, and on a whole, it doesn't cause 
me TOO much trouble. For a while I was getting hit with large scale spam 
attacks (dictionary type attacks), but that seems to have stopped. The 
only think I changed was my unknown account now issues an auto-reply 
saying the email was addressed to an unknown user and was forwarded to 
the mail admin to figure out who was supposed to get it. Within a few 
weeks of turning that on, dictionary attacks stopped, but it could just 
be coincidence, those spam runs only happened every once in a while 
anyway. I turned that on simply to correct the constant offenders that 
were too lazy to update their address book to fix an email address 
spelling mistake... it also worked well on that front. Now I am down to 
getting just the legitimate unknown traffic.
