I have a strange situation. I have one user sending Internet mail to one specific email address that bounces with this error message: "Action: failed Status: 5.0.0 Diagnostic-Code: smtp;553 Requested action not taken: mailbox name not allowed"
All other users can send to that email address OK, and the user in question has no problems sending to other outside email addresses. This is an Exchange 5.5 sp4 /Outlook 2000 install. I have already tried the following: 1) Log into Outlook as the user on another PC and send mail - bounces with same error. 2) Telnet directly to the recipient's mail server and send mail as this user - this works. 3) Send mail from me to the recipient - this goes through without a problem. I have not been able to find a "good" explanation of this particular SMTP error message. Any suggestions?
