Or, in the case of the "after EHLO", it was dropped. It's possible that the client saw something unsuitable in the EHLO response and dropped the connection, knowing mail could not be delivered. In that case, check the client's logs. It does not tell the server its reasoning in making such a decision. If as per the snippet, more of the disconnects are "after CONNECT" and not "after EHLO", Noel's theory sounds more likely. But it is a good idea to look into the client's side of the story, too. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
