There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<BECSBS.bec.lan #5.5.0 smtp;550 Unknown user>"
A couple of days ago we received an email from a client of ours. One of our employees replied to the email and when he sent the email, he immediately receives the above NDR report. Seeing as how we are replying to an email, we know that this address exists.
Now I have been running tests here and there. I am able to telnet into my exchange server on port 25, run the tests against the email. As far as the telnet test is concerned, it says there are no problems. But immediately we get a NDR report that is listed above.
I am at a loss here, and could really use some expert help!
Thanks in advance!
