cPanel - Email Filters

Email filters are useful to create rules to block unwanted emails, based on certain rules you choose. You can specify some rules like a message containing a specific word should be deleted or passed to a specific program.
These filters work subsequently, for example if a mail passes through a filter, but can be blocked by another filter. You can specify multiple rules in one filter too.
There are two types of Email Filters in cPanel − User Level Filter and Account Level Filter.

Account Level Filtering

To Create and Manage Global Email Filter click on Global Email Filter found under Email section of cPanel Home.
Process to Create, Manage and Test a Global Email Filter is same as we studied above in User Level Filtering. Only difference is that you will not find a list of Emails to choose to Manage, but you will get a list of all Global Email Filters.
