FAQ
SPF (Sender Policy Framework) is a DNS record indicating which servers are authorized to send email on behalf of your domain. It helps protect the domain from sender spoofing and spam.
The SPF standard allows no more than 10 DNS queries when verifying a record. Exceeding the limit may cause messages to be rejected by recipients.
