Hi,

For antispam it's important that a receiving mailserver can resolve the ip
of the sender to a machinename on a domain, reverse DNS.

But my server operates in an .local extension network, but it handles .nl
email. How do I setup a good PRT entry so reveiving MTA's can resolve my ISP
IP to a machinename? For example, assum that my mailserver got machinename
evil. Internal this machine can be found at evil.domain.local. But I can't
setup an PRT for my .local domain at my ISP.

The reverse DNS recommendation applies to your Internet domain. Your ISP
would be the one who would have to set up a PTR entry.
