Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to seem as being sent from another one, generally with the idea to scam the recipient someway. When SPF protection is activated for a domain, a unique record is generated for it in the Domain Name System and all of the DNS servers around the world receive it. The record includes all the e-mail servers that are allowed to send valid messages from an email address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when its sending server is permitted, the message is sent to the target receiver. In case, however, the sending server is not present in the SPF record for the specified domain, the message will not be sent and it will be discarded. In the event that you employ this service, it will stop third parties from sending spam messages which appear to have been sent by you.

SPF Protection in Web Hosting

When you host your domain names in a web hosting account with us and we handle the e-mails for them, you will be able to activate SPF protection for any of them with a few clicks inside your Hepsia Control Panel. This service is available in its own section where you will be able to view which domains are currently protected. For the ones that are not, you will be able to activate the SPF protection service and set up a lot of things in the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and even to create a rule that messages can be sent only if your domain names have our MX records. The aforementioned solution is the most secure one, and it can be used if we manage the e-mails for your domains and you are not using a different e-mail supplier. The newly generated records will propagate within 1 day and nobody will be able to fake the FROM field in a message with your addresses.
