Remove spam check when using external spam filtering?

[kenneth-vkd]

Hi
Some of our customers use external spam filtering services for their email accounts.
After migrating some of these customers to our new WHM/cPanel infrastructure, we have started to get reports of all incoming email being prefixed with "***SPAM***".
To fix the issue, we tried to whitelist the IP-addresses of the spam filtering services SMTP servers, in the Apache SpamAsassin configuration for an affected cPanel account.

How can we make it so that when using a spam filtering service, then the email is not spam checked in cPanel or at least the "***SPAM***" is not added?

Hello,

You could add the IP addresses of the spam filtering SMTP servers to the "Trusted SMTP IP addresses" option under the "Access Lists" tab in "WHM >> Exim Configuration Manager >> Basic Editor". Per it's description:

IP addresses exempt from all SMTP sender, recipient, spam, and relaying checks. IP addresses you enter here are stored in /etc/skipsmtpcheckhosts. These senders must still use an RFC-compliant HELO name if the Require RFC-compliant HELO setting is enabled.

Thank you.
