It is hard to imagine any significant controversy over its contents. Since this is a BCP document, a conservative set of sound practices is consistent with the goals. This is IMHO a sound document. My only comment is, that if the intent of the last bullet in section 3 is to reduce backscatter, * MDAs SHALL NOT accept mail to recipients for which that MDA has no arrangement to perform delivery. then it should apply not only to the MDA, but more generally to (inbound) gateways and backup MX hosts. In other words, the definition of an MDA needs to be extended to include all MX hosts for the recipient's domain, rather than just the systems performing the actual mailbox delivery. Likely, instead of redefining MDA from its usual meaning, a more suitable term should be used for the role of an MTA which is an MX host for the recipient's domain.
