I noticed that dns.resolveMx would sometimes return MX records unsorted by priority.
This pull request ensures that the MX record that gets chosen has the highest priority.
Unfortunately I have no way to test this as I don't have access to DKIM keys.
I doubt there will be problems since this is a simple change.
