What do you mean?  DNS is about names and addresses, not roles.  If it's
one box, it only needs one name.

But if you want to give it two names (e.g. ns.company.com and
smtp.company.com), it doesn't matter which one you put in the reverse DNS.
Nothing typically performs reverse DNS on nameserver names, but mailserver
names get put in "Received:" headers, so I recommend making the reverse DNS
point to the mailserver name.
