Email filters in cPanel sort or discard messages for one mailbox based on rules you define.
Create a filter
- Log in to cPanel from clients.cidhosting.net.
- Email → Email Filters.
- Choose Manage Filters for the mailbox.
- Click Create a New Filter.
- Name the filter, set conditions (From, Subject, and so on), choose an action (Deliver to folder, Discard, Redirect), and save.
Tip: Test with a mild rule first. Aggressive discard rules can drop real mail.
