Seems, this is not a real problem, as far as initial greeting is not
hardcoded. In Zmailer it is 100% configurable now, so that's enough
for server admin to know about the problem and to decide if ESMTP
capabilities are really important for him/her. For me it is important
(early rejection of oversized messages, etc) - so I will try to
satisfy all stupid clients.
Again, IMHO it is not a problem. It is just an information issue for
Zmailer configuration, nothing more.
