Exchange2000 implements pipelining as per RFC2197. It actually improves performance.
I do not know how to disable it, but perhaps using an SMTP relay of a different species afront of your Exchange Server, like Postfix or Sendmail perhaps? William -----Original Message----- From: JAC Software [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 25, 2002 12:16 AM To: MS-Exchange Admin Issues Subject: Exchange and Exim I have a problem with my Exchange 2000 server, receiving messages from Exim mail servers. I can't receive messages from Exim 3.32 and 3.35 servers (maybe other versions, but Exim is the only one for which this has occurred). The NDR received by the sender contains a 500 5.3.3 Unrecognized command error. Advice I have received from elsewhere suggests that the problem may be in pipelining, so I am trying to find out how to disable pipelining on the Exchange server to test that theory. Any ideas on how I can do that?
