MX is optional for the domain. If no IN MX is delegated mails are delivered to whatever is set in IN A for that domain (that also means that you may not delegate IN A if you got IN MX and no plans to use anything that mails for that domain). > Basically an email from [email protected] to > [email protected] was DENIED_SENDER_NO_MX (sending IP's rDNS was > mail.sending-domain.com) > sending-domain.com DOES have an MX record but mail.sending-domain.com > does not. To me this may be a bug as from what you said, mail.sending-domain.com is just a messenger and it does need to even accept incoming mails, therefore lack of MX of mail.sending-domain.com is perfectly fine. Also, for the same reson, it would be wrong assumption that mail.sending-domain.com shall match one of MXes for sending-domain.com. Regards, -- "Daddy, what "Formatting drive C:" means?"...
