How to Whitelist an Email Address in cPanel
If important mail from a known contact keeps landing in spam, whitelisting guarantees it always reaches the inbox.
Step-by-step
- Open Email → Spam Filters in cPanel.
- Click "Show Additional Configurations" then "Edit Spam Whitelist Settings" (whitelist_from).
- Add the sender address — e.g. accounts@supplier.com — or a whole domain with *@supplier.com.
- Click Update Whitelist (whitelist_from). Mail from those senders now bypasses spam scoring.
- For a single mailbox instead of the whole domain, create an email filter that delivers from that sender straight to the inbox.
- Test by asking the contact to send a message and confirming it lands in the inbox.
💡 Good to know
- Whitelisting bypasses spam checks, so only add senders you fully trust.
- The opposite is blacklisting persistent junk senders.
- If genuine mail is widely going to spam, also fix your own SPF/DKIM.
