Hi,
Recently I started receiving 551 error with User unknown in virtual mailbox table when sending an email to a specific user, I used to send emails fine to him..suddenly, I received the mentioned error.
I followed Igor's advice in : http://forum.parallels.com/showthread.php?t=105131
I added the recipient email manually using the last command, and now it send...
Why wasn't that email automatically added? do i have to add recipients manually each time?
What could be the problem?
Here is my main.cf:
