When I set-up my site with i-mscp, I have configured the MX to an external server. Later we have changed our mind and decided to use i-mscp as out mail server. Now when we have deleted that MX record but server is not accepting any email. The mails bounces back with this message -
- ww0.host.com gave this error:
- <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table
I thought the error is happening because there is not MX record. I have other domains with the same i-mscp and they also do not have any MX and mails works fine with those domains. Later I thought as this domain had MX and we have removed it, this may cause the problem. So I have created MX again and pointed it to domain.com but that also did not solve the problem.
Did anyone have similar problem or can share a solution with me?
