Usually there is a reporting MTA associated with the message. Did you not get one of those? -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@xxxxxxxx] Sent: Wednesday, June 16, 2004 1:35 PM To: [ExchangeList] Subject: [exchangelist] domain isn't in my list of allowed rcpthosts message http://www.MSExchange.org/ Don't laugh at this one, I truely can't find the answer to this. The boss replied to a message from his Blackberry and got the response below. I did a search on the web for the error and most everything pointed to issues that don't apply here. My main question is are such messages are usually generated as a result of an issue on our side or their side? This has happened only once, but it was the boss' email.
