Exchange errors. How to verify configuration?

  • 772

They are having trouble with mail delivery (some get through, others don't).
What do you suggest I do to check the server configuration?

This is an SMTP protocol error log for virtual server ID 1, connection #621. The remote host "212.52.84.180", responded to the SMTP command "rcpt" with "550 #5.1.0 Address rejected [email protected] ". The full command sent was "RCPT TO: ". This will probably cause the connection to fail.

  1. It seems pretty clear to me:

    The remote host "212.52.84.180", responded to the SMTP command "rcpt" with "550 #5.1.0 Address rejected [email protected]

    The recipient address was rejected. Have you verified that this is a valid email address?

    This message indicates a DNS problem or an IP address configuration problem

    Have you verfied that the remote domain exists and that the MX or A record for the remote domain can be resolved?
