I installed and configured postfix admin for postfix mta administration (virtual users in mysql) on a debian 12 mail server which also acts as a gateway for the local network (192.168.xx.xx).
Everything is ok, until I needed an alias like alias@domain.com to direct emails to user1@domain.com and user2@domain.com.
From the other domain alias works ok, from my domains, with address like any_address@domain.com, with e-mail client (outlook, thunderbird...) any email sent to alias@domain.com returns the error "User doesn't exist: alias@domain.com"

How do I set alias@domain.com in postfix admin so that it is correct for email clients?
Thanks!

Wild guess: your local clients use a different entry in master.cf, and this entry has something like -o receive_override_options=no_address_mappings

Also make sure that the affected domain is only listed in PostixAdmin, but not in main.cf as mydestination (with your anonymized main.cf, I can't tell if that's the case)

BTW: PostfixAdmin moved to https://github.com/postfixadmin/postfixadmin/ - you'll get better and possibly faster support there.
