Actually, this hasn't been implemented yet. That is to say, it is
possible using the sanitizer and a clever sendmail configuration, but
noone has done so yet as far as I know.
The main difference would be that when you are dealing with outgoing
traffic you will want to use very different rules from those you use
for incoming traffic. For example, I wouldn't want partial or
rewritten messages to leave the company - I would want infected
messages stopped and possibly forwarded to the local admin so he
knows that one of his users has an infected machine.
One way this could be done would be to use relatively simple procmail rules
that check the sanitizer's exit code.
