Actually the reverse pointer doesn't have to match. In fact this is impossible
if you are setting up virtual accounts on one server for different domains. You
just need to have a reverse pointer.
Most email servers look to seen if the reverse pointer has a "dyn" in it and
blocks those.

In order to prevent ending up in spam in GMail, it is necessary to
have working DKIM and/or SPF for your messages and forward- and
reverse DNS records for your mailserver match.
