I have a client trying to send mail to a "large" organization that has three MX records. the lowest MX is a server that rejects my clients email, The receiving organization knows that there is a problem with that particular server but won't remove it from DNS. Ergo, once or twice a day, we get a rejection when our mail hits that server. Is there anything I can do from my side to prevent our mail server from ever selecting that one MX record to send the mail to?
Sorry, I just can't get them to listen and I need to get mail delivered.
thanx for any suggestions.
