        If N recipients at a site are getting the same exact message, you
enter multiple RCPT TO lines and one DATA entry.  If N recipients at a site
are getting N different messages, you use RSET to reuse the existing SMTP
connection (something I've never fully trusted the PC-mail-store vendors to
get right, quite frankly).  Sendmail defaults to doing the former, but not
the latter, if I recall (and I don't, 'cause I haven't screwed with sendmail
for years, so don't get on my case if I'm wrong.)

        Qmail gets better performance by opening multiple connections in
parallel.  ORBS thinks that this is too greedy of an algorithm.  Presumably
they'd rather save the bandwidth for more useful business traffic like
Napster or Quake.  I find it hard to see how someone working at an
organization dedicated to protecting the mail infrastructure can say
something like "treating smtp as low priority data."
