Potentially dumb question: what does this magic meaning MX target (.) offer, that a target resolving to a null address (0.0.0.0 and/or ::0) does not? No protocol or code changes required. The null address does, after all, mean no service offered here. (Now, if only load-balancer vendors could

Well OK, so it's a semi-dumb question. But if we're going to assign magic meaning to something, why not assign magic meaning to the null address *specifically*in*the*context*of*SMTP*message*delivery*strategy*, i.e. auto-fail messages destined for the null address and never retry them? To

OK, fair enough. Just as long as we understand and properly record the design decision that was made here: I.e. we're more afraid of the negative consequences of software/OSes that don't treat null addresses reasonably (i.e. pointless/doomed retries, possible self-looping) than we are of the
