What "variable" ? Unless it is defined in the same main.cf file, or

Unless myhostname is explicitly defined, postfix uses the FQDN
returned by gethostname(2).
What I meant is that I don't have the hostname hard coded into the
main.cf file, but am defining it using $myhostname -- which should
resolve correctly
Received: from*mx2.domain.com* (*mx4.domain.com* [*AAA.BBB.CCC.157*])
This message was received from a machine claiming to be
mx2.domain.com; however, the machine's IP resolves to (has a PTR
record of) mx4.domain.com.
Thank you! I was looking for an explanation of exactly what this line
meant and your spelling it out helped me solve the problem. The DNS was
OK as I had thought BUT when I had allowed this machine an outgoing
connection through our edge router, I made a mistake and did NAT on the
mx2 IP as the mx4 IP. That wasn't apparent to me in checking things over
because the mistake was on a secondary IP on that server which I wasn't
expecting or thinking about the connection going out on. UGH.
Thank you for responding to my issue and giving me some direction.
