Where is SA going to get the envelope sender from? Much of the time
it is not in the message itself.

I think all sites are supposed to have an MX record. Certainly the
MTAs I've encountered do fallback to an A record if there is no MX
record. For myself I've added a counter test so that ddts.net and
dyndns.org domains don't get any net score from the no MX test.
