Sorry, I can't parse that. You've given them a HELO by initiating an SMTP connection to them. They have it from that point; I don't see how they "can't get it". Does the HELO you send have an rDNS? Does a forward lookup on the result of the reverse lookup match? > They are not doing a callback based > on the MX record, but instead on the sending IP.
