Resolved Postfix error / Recipient address rejected: User unknown in virtual mailbox table

Erwan

Regular Pleskian
Hi all,

We have problem with some users (user1@domainA.com) that send email to another with the same domain (user2@domainA.com):

550 5.1.1 <user2@domainA.com>: Recipient address rejected: User unknown in virtual mailbox table

We try to repair:
#plesk repair mail

But still the problem.
All seems to be correct in plesk panel email.

The problem is only with two users of the domain, not with others.

An idea? We are with Postfix/dovecot.
We don't have change anything.

Erwan
