I am getting spam from my own domain

I am getting spam that looks as it is coming from my own domain:

Example:

in this here case if the domain is secpoint.com

the spam would appear as it comes from [e-mail]

To solve this you need to make sure your own domain is not in the white list.

Example if you navigate to

https://YOURIP/spprotector/setuplists.php

Then make sure your domain is not listed there.
