Yes to both. The domain is listed in the domains table and the user address ([email protected]) is listed in the email field of the users table. I hope I haven't stumped you. I do feel it is an SASL issue since my previous setup had permit_mynetworks before permit_sasl_authenticated in the smtpd_senders configuration variable. It is currently blank. That is just a theory right now though I plan on testing that this evening.
