What is SPF (Sender Policy Framework)?
SPF (Sender Policy Framework) is an email authentication method used to prevent email spoofing and unauthorized use of domain names in email messages. It allows domain owners to specify which mail servers are authorised to send emails on behalf of their domain, helping recipients verify the authenticity of incoming emails.
Why Should SPF Be Used?
Enhanced Email Security: SPF helps protect against email spoofing and phishing attacks by allowing recipients to verify that emails claiming to be from a specific domain were sent from authorised mail servers.
Reduced Spam and Fraud: By implementing SPF, domain owners can reduce the risk of their domain being used for malicious purposes, such as sending spam or fraudulent emails.
Improved Email Deliverability: SPF can improve the deliverability of legitimate emails by reducing the likelihood of them being flagged as spam or rejected by email filters.
Compliance Requirements: Some industries and regulatory bodies may require or recommend the use of SPF as part of compliance with email security standards and regulations.
SPF plays a crucial role in email security, safeguarding both domain owners and recipients from email-based threats and ensuring the integrity and authenticity of email communications.
Any domain name mapped to our mail platform with the name servers pointing to us will automatically have SPF added. However, if you prefer to have your domain names with a third party, then you may need to use the following.
If you send through our SMTP servers, then the following SPF record will work for you:
"v=spf1 include:_spf.interdns.co.uk -all"
To apply this:
1. Access the DNS page for a domain name
2. Click on 'add record' under the 'A, AAAA, CNAME & TXT Records' title
3. Select the type as TXT
4. Leave host as blank
5. Leave TTL as 3600
6. Enter the Record Value as "v=spf1 include:_spf.interdns.co.uk -all" including the quotation marks
7. Press 'update' to save
