Frequently asked questions

What is an SPF record?

SPF (Sender Policy Framework) is a DNS TXT record that lists which servers may send email for your domain. Receiving servers use it to spot forged senders.

What is the SPF 10 lookup limit?

An SPF record may trigger at most 10 DNS lookups through include, a, mx and redirect mechanisms. Go over the limit and SPF fails, which can send legitimate email to spam.
