the SSP draft should mandate publishing MX records whenever an SSP record is also published.

SSP (or ASP) have no business to "mandate" MX records, that's not their job. MX records are not required for (2)821(bis) interoperability, and RFC 2119 has a very clear policy about arbitrary MUSTard.

The MUST only occurs in conjunction with publishing SSP records. This does not mandate publishing of MX records when SSP is not used.

-1 to this proposal, for the reasons that Wietse and Frank have mentioned. Furthermore, if the domain publishes an SSP record, the SSP lookup algorithm never gets to the step that might benefit from the publication of an MX record.
