Overview

The SPF (Sender Policy Framework) setup ensures that your domain is protected against email spoofing and phishing attempts. This guide will walk you through the process of setting up SPF for your domain.

Step-by-Step Guide to Setting Up SPF

Step 1: Access Your DNS Settings

1. Log in to your domain provider’s control panel (e.g., GoDaddy, Cloud flare, Name cheap).
2. Navigate to the DNS Management or Advanced DNS Settings section.

Step 2: Add an SPF TXT Record

1.  Look for the option to Add a New Record and select TXT Record.
2.  In the Name/Host field, enter @ (or leave it blank, depending on your provider).
3. In the Value field, enter the SPF rule based on your email provider. For example:
   • If you use multiple email services, include them as needed (refer to your provider’s SPF guidelines).

Step 3: Save and Apply Changes

1. Click Save to apply the new record.
2.  Wait for DNS propagation (this may take a few hours).

Step 4: Verify SPF Configuration

1.  Use SPF lookup tools such as:
   • MXToolbox SPF Checker
   • Google Admin Toolbox
2.  Ensure that your SPF record is valid and correctly formatted.

Understanding SPF Policies

• +all (Allow all) – Not recommended as it permits all senders.
•  ~all (Soft fail) – Recommended as it marks unauthorized senders without blocking them.
•   -all (Hard fail) – Strictest option, blocking all unauthorized emails.

Troubleshooting Common SPF Issues

•   SPF Not Found? Ensure the TXT record was added correctly in the DNS settings.
• Too Many DNS Lookups? Reduce the number of include statements to avoid exceeding the limit.
• SPF Failures? Verify that your email provider’s IPs are correctly included in the record.

By following this guide, you can improve your email deliverability and protect your domain from spoofing attacks.
