It strikes me that I haven't seen a general answer to the original question
how to set up PTR records when one is serving more than one domain under
the same IP address.
don't setup PTR records and A records for a mailsever
setup *one* PTR record, *one* A record and *one* HELO-name
just use a generic hostname like "mail.yourcompany.tld" and
use that as MX records for as many domains you are hosting
on that mailserver
that:
a) works
b) is consistent
c) don't bring you in trouble if it comes to TLS
d) keeps things simple
proven by hosting some hundret domains for a decade on one hostname
True. And that's pretty much what I've ended up doing.
One minor nit, though: when one is hosting email for clients, the
generic hostname needs to be something innocuous (for example, when you
use godaddy's mail services, all the mail goes out from
xxxx.secureserver.net).
