Yes I know, what I was asking is what is the "normal" configuration
that mimedefang users are choosing...

I'm sure there is pro's and con's and an accepted better way to do it...

P. S.

  If spam assassin is really as good as they say...
  Is rbl lookups even needed...?
  From what I understand delay from dns replies,
     makes the system sluggish and viable for DOS attacks correct ?
