mail duplicated

Operating system CentOS Linux 7.3.1611

Webmin version 1.831

Virtualmin version 5.07

mail configured with postfix

  1. I am getting every mail twice to my inbox
  2. Each mail that I send is going also to my inbox

(The problem might be related to the change of the virtualmin domain)

Please advice and specify any needed information and the commands to get it

Many thanks

First you should update your Webmin (v.1.844) and Virtualmin (v.5.99). Then if the problem still persist you should post little more information, e.g. log files would help.
