Looks like that rejection message is coming from your customer SMTP
server and not your server ... Possibly Microsoft Exchange Server.

Have you checked your /var/log/maillog and match the time-stamp
on the error message with smtp entries in your logs.

Was the error message sent from your MAIL-DAEMON?
