It adds one small transaction to the SMTP conversation, and only has to be
done once per convo (per send session, that is). I can't imagine that it
will cause any noticeable performance issues, unless you're talking about
14.4 connections or something. I mean, with tens of thousands of users,
the extra bytes and Mhz MIGHT add up to a tiny hit, but it's the right way
to go. In fact, you should just look at it as the only way to go...as if
you left out a step...since this list strongly suggests it.
