Strange problem here: we running Outlook 2003 and there's one user with a unique problem. He can email my boss who uses AOL email and my boss can receive it with no problem but when he tries to reply he gets the following message: Diagnostic-Code: SMTP; 550 5.7.1 n53DbCwM005305 This message does not comply with required standards. It also says "Your e-mail is being returned to you because there was a problem with its
delivery. The address which was undeliverable is listed in the section
labeled: "----- The following addresses had permanent fatal errors -----". Mind you this is replying to the original message.
