Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called email spoofing where an e-mail message is sent from one e-mail, but to look as being sent from another one, usually with the purpose to fraud the recipient someway. When SPF protection is activated for a domain name, a special record is made for it in the Domain Name System and all DNS servers around the world get it. The record includes all e-mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted receiver. In case, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message won't be sent and it'll be discarded. In the event that you use this solution, it will stop third parties from sending spam emails which look as if they have been sent from you.

SPF Protection in Cloud Hosting

When you host your domains in a cloud hosting account with us and we manage the e-mail addresses for them, you'll be able to activate SPF protection for all of them with several clicks in your Hepsia Control Panel. This service is available in a separate section where you'll be able to view which domains are currently secured. For those which aren't, you will be able to activate the SPF protection solution and set up a lot of things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, as well as 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, and it can be used if we manage the email addresses for your domains and you're not using a different email supplier. The new records will propagate within 24 hours and nobody will be able to forge the FROM field in an e-mail by using your email addresses.
