You don't.  Sendmail, at least, is smart enough to deliver local mail
without doing through the relay - at least for things in the same
domain.

For other domains, sendmail provides mailtable which is a way to decide
which relay should be used for which domains.  (I just confirmed this
with the sendmail gurus.)  I assume postfix has something analogous.

Also, I checked with DuoCircle and they claim to only retain the content
for a day in their logs, but are willing to turn that off at the request
of the customer.
