Here are the instructions for setting up SPF and DKIM authentication for your domains. You will need to add one (1) TXT record and three (3) CNAME records to your domains DNS settings:
- Login to your web hosting account cPanel
- Find the Domains section and click Zone Editor
- Click the Manage button
- Click on the Add Record button and add the TXT and CNAME records that was emailed to you.
- After adding the records, your DNS settings should contain 4 new records (sample shown below).
It will take about 24 hours for the new SPF and DKIM settings to be propagated around the world.
