actually...the real problem is that since ip addresses aren't necessarily allocated on octet boundaries, you'd need more than one set of mx records at the boundary point in the dns. just having 165.165.in-addr.arpa. MX 10 noc.tor.hookup.net. MX 20 vertex.tor.hookup.net. wouldn't work if 165.165.0.0/16 was divided up into a few /18 or /19 blocks and used by different providers.
Sorry, off topic, just had to get my gripe in there.
