Hi,
Two possibilities I can think of:
a) Their mail server is mis-configured (always a possibility I suppose)
b) The mail you are attempting to deliver is not destined for @domain.com
-or- purports to be from @domain.com but the remote server does not have your
host as an acceptable source of mail from @domain.com (the error message is
basically saying that relay is prohibited. Relaying is the process of sending
mail not destined for your domain through your mail server)
HTH
Cheers
Ken
