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.
