Solution:
I got it fixed with very simple trick. :P


1. Login to plesk control of the server as a admin user.
2. Select the domain from "Domains" and click on its "Services>> Mail" option.
3. Then, disable the mail service for that domain by clicking on "Switch Off" and then re-enable the mail service.
