This host is incorrectly configured. Since it has two interfaces,
DNS should have something like:
Host:
somehost.example.org IN A 10.1.2.3
somehost.example.org IN A 10.2.3.4
interface.example.org IN A 10.2.3.4
Interfaces:
somehost.example.org address 10.1.2.3
interface.example.org address 10.2.3.4
You get a connection from 10.2.3.4, HELO somehost.example.org
You ask PTR(10.2.3.4) and get interface.example.org
You do *not* ask for PTR. You ask for A(somehost.example.org).
Or you ask A(somehost.example.org) and get 10.1.2.3
*and* 10.2.3.4.
Instead of multiple IPs for the HELO name, if said host wants to use a
different name for the second interface, it should use that name when
connecting with it!
