HOW TO: Whitelist intenal cpanel emails

[DigitalEssence]

Hi,

I've noticed that the cPanel disk usage emails sent to hosted clients were all marked as low spam.

The emails were sent from cpanel@local-domain-name with a client IP of 127.0.0.1 and tripped the KAM_MAILBOX2 rule with a score of 6.25.

The KAM_MAILBOX2 rule relates to Mailbox Quota Phishing Scams.

How do I stop internal cpanel emails from triggering this rule while keeping the score as it is to stop real phishing scams?

I've searched and dug about a bit but can't find anything to even get me started.

many thanks,
