It sounds like a Postfix problem, so cranking up Postfix logging is probably going to be the most fruitful avenue.
I understand this, of course this is the postfix issue, I see the error in maiillog:
May 30 00:50:03 host postfix/smtpd: NOQUEUE: reject: RCPT from mail-wg0-f46.google.com[188.8.131.52]: 550 5.1.1 email@example.com: Recipient address rejected: User unknown in virtual alias table; firstname.lastname@example.org email@example.com proto=ESMTP helo=<mail-wg0-f46.google.com>
But I have everything required by installation manual in the main.conf so I have no idea what going wrong and how to debug this wrong alias problem.
