In general, an SMTP server cannot know whether the SMTP client is MS
Outlook or Sendmail.

The whole business of sending back part of a multiline reply to trick
the client into extending its timeout seems smelly to me.  In today's
environment when you might have hostile servers trying to tarpit
clients, I can see a client not wanting to extend its timeout just
because a network packets are trickling in.  The proper way to do
in-progress reply codes is to make an in-progress ESMTP extension that
the server advertises and the client asks for.
