Are you using X400 to transport the message at any point in its routing? Is the target server Lotus Notes?

How do I fix this problem since the message is not actually a spam? The "domain-relay.mspring.net" was the host server saying that "Sender domain not compliant with RFC 822, section 6.2.7".

The mail server at the other end thinks it is a relay. ----- Original Message ----- From: Andrea Coppini <mailto:andreacoppini@xxxxxxxx> To: [ExchangeList] <mailto:exchangelist@xxxxxxxxxxxxx> Sent: Tuesday, September 03, 2002 6:05 PM Subject: [exchangelist] RE: Error on bouced email messages http://www.MSExchange.org/ <http://www.MSExchange.org/> It looks like some sort of Spam protection on the recieving end.
