I see nothing about the failure. All seems to go fine, Postfix establishes a connection with remote server and silently fails :-/ Put Postfix into a more verbose logging. In "main.cf": *** debug_peer_level = 2 debug_peer_list = NEWSERVER *** Reload Postfix and try again. P.S. 1 - Check the more basic here: saslauth mechanisms being used for authenticating and of course, a correct password in "/etc/postfix/ sasl_passwd" O:-) P.S. 2 - Remember that "535 5.7.3 Authentication unsuccessful" is a message coming from Exchange server -not Postfix- so it would be great if you could review the logs from the MS server side.
