Ah, i wondered what you meant.

Hmm...ok. dot-whatever != local delivery agent. I guess I should say it 
boils down to what qmail-local and its dot-qmail mechanism does compared 
with the pairing of sendmail's local mailer and its dot-forward 
mechanism and postfix's local (that is what its LDA is called) support 
of sendmail's dot-forward.

=D. Got me there. The only exception being qmail...once a message is 
queued, its routing has been set whereas you can still change that if it 
  were postfix, sendmail and I guess exim.
