I've sent in a new version of draft-levine-dns-mailbox-01 that describes a bunch of ways to encode mail address local parts in ways that don't need canonicalization or address guessing.
Take a particular look at section 5, which publishes regular expressions to match a domain's mail addresses. * Can represent any plausible local part syntax including case folding, noise characters, multiple ways to write Unicode characters, suffixes where some are ignored and some aren't, BATV, and VERP. * Reasonably fast lookup (max of one query per localpart character) * Works fine with static zones served by ordinary name servers . * Doesn't make bulk addresss harvesting easy. If you really want to do experiments in publishing mail info in the DNS, I think this would be a rather interesting one.
