Specifically, since I need to set up a PTR to point to the server, any

The DNS name (and reverse DNS) of the server doesn't need to have any
relation to domains using the server. It just needs to be consistent with
itself
i.e. The DNS, reverse DNS and what the SMTP server calls itself all need to
be the same
If the DNS name needed to relate to the email domains, then ISPs and ESPs
couldn't possibly work.
You use SPF to link the IP address to the domains using it.
