SPF, which is an acronym for Sender Policy Framework, is an email protection system, that is is intended to verify if an email message is sent by a certified server. Using SPF protection for a particular domain will stop the counterfeiting of email addresses generated with the domain. In simple words: enabling this function for a domain name generates a special record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send emails from mailboxes using the domain. When this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it uses tests if it comes from an accredited server. If it does, it's forwarded to the destination address, however when it doesn't come from a server part of the SPF record for the domain, it's rejected. Thus nobody will mask an e-mail address then make it look as if you're e-mailing spam messages. This method is also known as email spoofing.

SPF Protection in Shared Hosting

If you host your domain names in a shared hosting account with us and we manage the email addresses for them, you'll be able to activate SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service is accessible in a section of its own where you're able to see which domain names are already secured. For those that are not, you will be able to activate the SPF protection solution and set up numerous things at the same time - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that email messages can be sent only when your domains include our MX records. The last mentioned option is the most secure one, but you can use it in the event that we manage the e-mail addresses for your domain names and you're not using a different e-mail provider. The newly generated records will propagate within 24 hours and nobody will be able to fake the FROM field in a message by using your addresses.
