The Sender Policy Framework (SPF) is an email authentication system that detects forged sender addresses while the email is being delivered. SPF, on the other hand, is confined to detecting a forged sender claim in the email’s envelope, which is used when it bounces.
To set up SPF on your Mailgun account, follow these steps :
- Login to your DNS console and go to Advanced DNS settings to add or modify an SPF record.
- You can either add a new SPF record or modify the existing one. To modify a record, follow these steps :
- In your pre-existing SPF record, add include:mailgun.org. If your record looked something like v=spf1 include:spf.google.com ~all, after modification, it should look like
v=spf1 include:spf.zoho.com include:mailgun.org ~all. - Save changes.
- In your pre-existing SPF record, add include:mailgun.org. If your record looked something like v=spf1 include:spf.google.com ~all, after modification, it should look like
- To add a new record altogether, follow these steps:
- Enter the values as shown below:
Name: Enter @ or leave it empty.
TTL: Enter 3600 or default
Value:v=spf1 include:mailgun.org ~all \ - Now, save changes and wait for 24-48 hours for your DNS to apply the records.
