As a possible fly in this keep alive ointment is RFC 2821 section
which *already* implies that the timeout should be until the FINAL reply
code rather than between each line of the reply. In particular, see the
description of the DATA timeout:

   DATA Termination: 10 minutes.
      This is while awaiting the "250 OK" reply.

This looks like the final reply code to me and I can believe that many SMTP
Client writers would interpret it this way.
