Frequently asked questions

What is an SPF record?
SPF (Sender Policy Framework) is a DNS TXT record that specifies which IP addresses and mail servers are authorised to send email on behalf of your domain. It helps prevent email spoofing.
What does ~all vs -all mean?
~all (softfail) marks unauthorised senders as suspicious but still delivers the email. -all (fail/hardfail) rejects or discards email from unauthorised senders. +all allows anyone (insecure). ?all is neutral.
My SPF record was not found. What does that mean?
The domain has no SPF record, which means all senders are technically allowed (no policy). This can make your domain vulnerable to spoofing. Add an SPF TXT record to your DNS.
What is the SPF lookup limit?
SPF limits DNS lookups to 10. Having too many include: mechanisms, redirect=, a:, mx:, exists:, and ptr: mechanisms can exceed this limit, causing SPF to permerror.
