A user is getting this particular NDR message, when REPLYING to a message from a specific account only, for Eg :- He receives an E-Mail from EXTERNAL_USER@xxxxxxxxxxxxxxxxxxx, when he replies to this mail he receives the following error From: System Administrator Sent: Sunday, November 23, 2003 11:05 AM To: 'najedpc@xxxxxxxxxxxx' Subject: Undeliverable: Drawings of Najed Plastic cards Factory. Your message did not reach some or all of the intended recipients. Subject: RE: Drawings of Najed Plastic cards Factory. Sent: 11/23/2003 11:05 AM The following recipient(s) could not be reached: 'najedpc@xxxxxxxxxxxx' on 11/23/2003 11:05 AM 554 Relay rejected for policy reasons. But when he composes a new message to the same address mentioned above, the E-Mail gets sent without any problems. This issue has started for another user as well now, it happens only when he REPLIES to an E-Mail he received from a Hotmail account. He can send a new mail to the same hotmail account without any problems, but he cannot reply to only this specific hotmail account, to all other hotmail accounts it works fine.
