Open cpanel and open:
- Home -> email -> Global filters (global filters affect the cPanel account’s email addresses.)
- Home -> email -> email filters (User level filters affect specific email addresses on the cPanel account.)
The first set of options specifies which part of the email message the system examines to determine whether the message matches your filter parameters. After you select the portion of the email message that the system will examine, select the type of comparison between that portion of the email and the criteria that you enter.
Enter the criteria to use in the text box under the Rules menus. The type of data that you enter determines the comparison that the system performs.
For example, if you select the From and Equals filters, enter email@example.com as the criteria. The system determines that any email from firstname.lastname@example.org matches the filter, but does not match email@example.com because it contains additional letters.
