 The SPF (Sender Policy Framework) is a TXT record on your DNS server that specifies which hosts are allowed to send mails for a given domain. When a mail server receives a mail that seems to come from your domain it can check if it’s a valid message. Some mail servers reject mails if they can’t validate that the message comes from an authorized mail server.
