DNSStuff is a bit too fussy here.

Your list is in the lists.mytimewithgod.net domain which does have an
MX pointing to mytimewithgod.net and mytimewithgod.net has a single A
record. Thus, mail to lists.mytimewithgod.net is delivered via
mytimewithgod.net which is fine. Also, mail to mytimewithgod.net will
work too because mytimewithgod.net has a single A record and even
though DNSStuff doesn't like it, this is sufficient for delivery of

I think this affects outgoing mail, not incoming mail. It may or may
not be required/desirable depending on whether you need/want Postfix
to deliver mail via the mailserver box.
