I am configuring Postfix and SOGo and when I trying to sent email from one local user to another I got the status bounced error, unknown user:

Error log:

Jun  9 09:26:28 mail postfix/local[24266]: 834D5442099: to=<user1@mydomain.by>, relay=local, delay=0.01, delays=0/0/0/0, dsn=5.1.1, status=bounced (unknown user: "user1")

Postmap full username lookup:

postmap -q user1@mydomain.by pgsql:/etc/postfix/pgsql/mailboxes.cf

Returns maildir:


Postmap short username lookup:

postmap -q user1 pgsql:/etc/postfix/pgsql/mailboxes.cf

Returns nothing

What I should change to get it worked? Thanks!
