RE: >>>>>>> I checked this setting and the value is blank. This is the field: / Deny messages to recipients in the following Internet domains or hostnames: / Could there be any other settings to check that would cause this error?
** Just about anything on that same tab, or in the server rules, as these are the places where you set policies on outbound messages. Also, if you change anything in the config, restart the router task to be sure the changes are obeyed.

RE: - check the RFC codes, and you'll find that "5.5.3" indicates "too many recipients" and 5.7.1 Delivery not authorized, message refused / - So this message was refused by the recipient server because there were too many recipients. They probably enabled something to block large numbers of recipients to prevent spam. / >>>>>>> The message that kicked back was addressed to a single indivdual and we don't generate a large number of messages to these domains that would cause the recipienet mail system to think we are spammers.
** Then the recipient's server is giving you the wrong information for WHY it was rejected. But it was rejected on their end, and you'll have to get them involved to get it fixed.
