Actually it is. I wrote the code and I know exactly what it is doing.

That's only part of the picture since of course your mailer doen't use
that hostname.

I thought it was obvious by now:

$ host -A animx.eu.org
*** animx.eu.org address 216.98.75.249 maps to hostname dial249.pm3abing3.abingdonpm.naxs.com
*** Hostname animx.eu.org does not belong to address 216.98.75.249
*** Not all addresses for hostname animx.eu.org have a matching hostname.

We're talking only about the public Internet here. What you do on your
own LAN is your own business.

It is indeed your configuration error, since it is your reverse DNS
which is broken.
