Re: 550-Mailbox unknown problem

The problem is in your configuration, examine more closely the
working and non-working accounts along with the postfix configuration
itself to isolate the specific cause of the problem.

Use WGM to verify the credentials of the working and non working
users, it could be as simple as the assigned mail server for the non
working users.
