Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called e-mail spoofing where an e-mail message can be sent from one email, but to appear as being sent from another one, frequently with the purpose to scam the recipient in some way. When SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all the DNS servers worldwide receive it. The record includes all the mail servers that are permitted to send authentic messages from an e-mail address under the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if the sending server is permitted, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the given domain, the message won't be sent and it will be discarded. When you employ this solution, it'll stop third parties from sending spam messages which seem to have been sent by you.

For those which aren't, you'll be able to activate the SPF protection option and configure a number of things in the process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only if your domains include our MX records. The last mentioned option is the most secure one, but it can be used when we take care of the emails for your domain names and you're not using another email supplier.
