cPanel email authentication
Set up SPF, DKIM, and mail routing for cPanel mailboxes.
Overview
cPanel often exposes email deliverability tools that generate SPF and DKIM records for hosted mail.
Recommended workflow
1
Open cPanel and find Email Deliverability.
2
Review the suggested SPF and DKIM records.
3
Apply records automatically if cPanel controls DNS, or copy them to your DNS host.
4
Confirm mail routing and MX records point to the cPanel host.
5
Run Outlio Test Domain Setup.
Tips that make this work better
Tip
If DNS is external, cPanel can show records but cannot publish them.
Tip
Use the exact DKIM host/value from cPanel.
Tip
Confirm SMTP and IMAP hosts match the mailbox server.
Common mistakes to avoid
- Assuming cPanel controls DNS when nameservers point elsewhere.
- Using website hosting records as mail records.
Done well, this should leave you with
A cleaner Outlio setup, fewer avoidable campaign issues, and a more reliable path from setup to replies.
