I am getting a lot of mail returned with the error message:
550 5.7.0 (BAY0-MC3-F54) Message could not be delivered. Please ensure the message is RFC 5322 compliant. (in reply to end of DATA command)
I need someone to check and see if this is just a matter of no such email address, or if there is something odd about my mail server configuration.
Skills: email, linux, dedicated server
