Log in to the cPanel administrative console.
- From the Mail section of the page, select MX Entry.
- In the Email Routing box, select Remote Mail Exchanger and click Change.
- Include the following MX record values: cloud7.spamtitan.com; cloud8.spamtitan.com (or, depending on which Cloud Cluster you are in, that could be: cloud1.spamtitan.com/cloud2.spamtitan.com or cloud3.spamtitan.com/cloud4.spamtitan.com. See SpamTitan Cloud Server IP Addresses)
- Click Add New Record.
- To add MX records for the additional servers, repeat steps 4 to 6 for those servers. Give backup servers a lower priority than the primary email server.
NOTE: Many cPanel servers require an MX record that contains the hostname of the cPanel server. This is used for mail routing and/or authentication. If after changing your MX records, you have issues with mail being rejected due to "too many hops" or authentication issues, add a 3rd MX record with a priority of 100 that contains the hostname of your cPanel server.
If you have to add a 3rd MX record for you cPanel server you may have to lock down your cPanel server to only accept mail from the SpamTitan server. See cPanel Configuration -- Account Settings to Only Receive From SpamTitan for more information.
