Thanks, Davide. I am the worst with RFC's - many of them seem to contradict each other, so this is just a question (not an attack or even a recommendation - I am very happy with XMail!)
I assume that querying the A record query is by design, based on your response, so I am wondering if there is a way to change that in the configuration. The Earthlink problem I am seeing is probably almost certainly related to this A record query. I printed this (and the RFC) earlier, but just for clarity: Earthlink says "The earthlink.net A record forwards port 25 connections to our outbound SMTP servers. Unless the mail server attempting the transaction maintains IP connectivity through the Earthlink network, delivery attempts through the A record will consequently fail and the above quoted error message will be returned." and that this is the fault of the MTA for being non-compliant with RFC 2821 (partially) shown below: RFC 2821, "Address Resolution and Mail Handling": "If one or more MX RRs are found for a given name, SMTP systems MUST NOT utilize any A RRs associated with that name unless they are located using the MX RRs; the "implicit MX" rule above applies only if there are no MX records present. If MX records are present, but none of them are usable, this situation MUST be reported as an error." So, any suggestions? Is there a way to prevent the A record query, or is there another sound reason not to prevent this?
