Re: Problem with aliass
I don't understand your situation.
Do you have any mail gateway, firewall stands in front of your mail server? Because there must be some log in iRedAPD log file since you have below setting in Postfix main.cf:
smtpd_recipient_restrictions = ..., check_policy_service inet:127.0.0.1:7777, permit_mynetworks, ...
Port 7777 is iRedAPD service.
