Alberto Bertogli 7fa40397c5 courier: SMTP falls back to A when MX does not exist ...

Make the SMTP courier fall back to the A record when MX does not exist, as per
standard behaviour.

This is not implemented nicely, because Go's API does not give a clear signal
if the answer was that there are no MX records or something else happens.
For now, we implement it with a heuristic that should work pretty reliably,
but it's definitely not very nice.
