> Running mailservice with Postfix
> PTR record is set to myserver.mydomain.com (1.2.3.4)

Check if your PTR record is traceable:

dig +trace -x 1.2.3.4 ptr

If that works check your resolver in /etc/resolv.conf, e.g.:
nameserver 127.0.0.1

dig @127.0.0.1 -x 1.2.3.4 ptr

You have a dns problem, not a postfix problem if any
of those fail.

Best regards,
Gerald
