Where is the PTR?
Reverse lookups on Public IPs are only good if they are in the DNS server
that is Authoritative over the public IP, which is usually the ISP that owns
the IP address.

For one MX records should not point to IP addresses, they should only point
to an A record. MX records for Publically available SMTP servers are only
queried if they are in the DNS servers listed on the Public record for a
domain.

Well, if the PTR is in the authoritative DNS and the MX record is in the
authoritative DNS SMTP servers will look them up and send mail for the
domain to the SMTP server named in the MX record.


I'm sorry, but you this is very unclear as to what your question is.
