There is no mention of host.foo.com in mail.foo.com's local-host-names (just
mail.foo.com and foo.com), currently host.foo.com's says the same thing (it
is our old mailserver - but from the error messages it is issues on the new
server -> nothing about issues w/ forged addresses)

Nothing too out of the ordinary, the normal localhost stuff, and the IP of
the firewall (which is the same ip as host.foo.com), but no host.foo.com

Both mail.foo.com and host.foo.com are A records.
