How do I use SpamExperts® with external DNS

If you're using an external DNS provider (Not recommended), and you've enabled SpamExperts® within cPanel, then you have to update your MX entries to make the spam filtering take effect.

Replace any existing MX records you have with the following:

TTL: 60
Priority: 10
Destination: mx01.hosting4real.net
---------
TTL: 60
Priority: 20
Destination: mx02.hosting4real.net
