Why the mailbox set doesn't exist?

Hi guys,

I get this error when I try to send an email to my new email box. I can see it in the IspConfig control panel but Gmail return me this message:

The error that the other server returned was: 550 550 sorry, no mailbox here by that name (#5.1.1) (state 14).

inside the /etc/postfix/virtusertable file the mail exists.

thanks for your support

 

Please check if the MX record of your domain points to the correct server:

Code:

dig mx yourdomain.com
