Hmm, the closest I can think of is RFC 2142, which defines standard
contact addresses for various services, and states that "if a given
service is offerred[sic], then the associated mailbox name(es) must be
supported."

Not sure how seriously anyone takes this one, and even a strict reading
wouldn't require mail just for having a domain name -- (though
webmaster@ would be required if the domain name were used for a website,
so it probably amounts to roughly the same thing).
