That was it. I didn't have any of the required options (reject, defer,
defer_if_permit, reject_unauth_destination) in my
smtpd_recipient_restrictions, so all email was being rejected. After
adding reject_unauth_destination, she's working beautifully. Thanks, I
think posting to the list helped. I probably would have given up and put
it off until later otherwise.
Kind regards,
