Cox blocking emails from a friends IP address
A good friend of ours is having a problem when he tries to send us and email. His emails to us are delayed and he receives a notification that they have been rejected by Cox, citing error code CDRBL. I understand that this error code means the the sending IP address has been temporarily blocked for exhibiting the characteristics of SPAM.
My friend is not a spammer. He is, however, fond of forwarding emails to his many friends and family.
Is there any way that I can ask Cox to stop blocking emails from him? I can provide his email address and IP address to Cox.
