This address no longer accepts mail Qmail – Plesk

It was a day again troubleshooting qmail mail delivery issue and found that qmail was rejecting emails to the domain which is hosted on same plesk server but was having other mail server.

The users were getting error : “This address no longer accepts mail”

Below fix worked out
we need to remove that domain from
/var/qmail/control/rcpthosts
/var/qmail/control/virtualdomains

and then need to restart the qmail service by
/etc/init.d/qmail restart
