Web Hosting Email: Change Incoming Global Email Spam Settings in cPanel

Note: This article only applies if you have web hosting with us at mywebhostingaccount.com.

You are able to globally adjust the incoming email spam filter settings in cPanel (applies to all domains and email addresses contained in cPanel).

Change the Spam Threshold Score (the likelihood of a message being marked as spam):

• In cPanel, go to the "Spam Filters" page (in the search box, type "spam", and the "Spam Filters" option will come up)
• You will most likely see the option enabled that says "Process New Emails and Mark them as Spam:", which is the "SpamAssassin". The "SpamAssassin" is the program that scores the emails for potential spam, and if the email scores above a number threshold, the message will be labeled as spam (more "SpamAssassin" info here: https://blog.cpanel.com/spam-filtering-on-cpanel-everything-you-need-to-know-about-spamassassin/). The default spam threshold score is 5. You can change the spam threshold score from the cPanel spam filters page by clicking the "Spam Threshold Score" link. Higher scores let more spam through.

Add Email Addresses and Domains to Whitelist or Blacklist:

• In cPanel, go to the "Spam Filters" page (in the search box, type "spam", and the "Spam Filters" option will come up)
• Under the heading "Additional Configurations (For Advanced Users):", click "Show Additional Configurations"
• Then click "Edit Spam Whitelist Settings" or "Edit Spam Blacklist Settings". 
• From the whitelist or blacklist page, click "Add a New ["whitelist_from" or "blacklist_from"] Item". There is cPanel documentation on some whitelisting and blacklisting settings here: cPanel - Whitelist and Blacklist. For example, you can whitelist or blacklist email from an entire domain by adding an asterisk before the @ symbol, like *@example.com.
