You can always allow (whitelist) or always block (blacklist) senders through the spam filter.
- Log in to cPanel and open Spam Filters.
- Click Show Additional Configurations.
- Use Whitelist (Emails Allowed) to add trusted senders, or Blacklist (Emails Blocked) to block unwanted ones.
- Enter a full address like
friend@example.com, or use a wildcard like*@example.comto cover a whole domain, then save.
For more control over what happens to blocked mail (such as deleting it or moving it to a folder), create a rule under Email Filters instead. Whitelisting is handy for newsletters that keep getting flagged as spam. If a sender is still blocked after whitelisting, please open a ticket.
