I was hoping someone could shed some light on this. A local user sent an email to another local user and got an undeliverable message with the error below:
The following Recipient(s) could not be reached:
User on 1/21/2009 3:40 PM
Your mail system could not find a way to successfully communicate with the destination system. Please notify your administrator.
<SERVERNAME #5.5.2 smtp;502 5.5.2 Error: command not recognized>
I'm not sure why they got that error, and the strange part is the recipient says they she recieved the email.
We are using Exchange 2003 SP2 and the email was sent with Outlook 2003.
