Common issues related to the Sender Policy Framework (SPF)
The main issue with SPF is that it must be configured for your domain, otherwise the Exchange Online Protection (EOP) will treat the email as spam or junk.
Resolution:
You have to correctly configure the SPF record in the required DNS provider or in the domain registrar.
Steps to add SPF record in Sigsync
What is TTL and Why is it Required?
TTL (Time to Live) defines how long a domain name server (DNS) caches changes to the SPF record before checking for updates. When configuring SPF records for your domain, you need to specify a TTL value, which is measured in seconds.
- A shorter TTL ensures that DNS changes propagate quickly but increases the load on the name server.
- A longer TTL reduces the server load but delays the propagation of any updates.
Best Practices for SPF Records:
- If your domain has multiple SPF records, verify all of them and consolidate into a single SPF record that includes all necessary information.
- Instead of creating new SPF records, update the existing record to add additional information.
- Once consolidated, remove any redundant SPF records to avoid conflicts.
This approach ensures proper SPF configuration and avoids potential email delivery issues.
Validate Your SPF Record
If your emails are being delivered to Spam or Junk folders, it may indicate that your SPF record is not properly configured. To verify, use third-party SPF validation tools such as kitterman.com to check your SPF record setup and ensure it is correctly implemented.
