Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different, ordinarily with the purpose to scam the recipient someway. When SPF protection is enabled for a domain name, a special record is generated for it in the Domain Name System and all DNS servers globally have it. The record contains all of the email servers that are allowed to send legitimate messages from an address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is sent to the targeted receiver. When, however, the sending server is not present in the SPF record for the particular domain, the email message won't be sent and it will be discarded. When you employ this solution, it will prevent third parties from sending spam which seem to have been sent by you.

SPF Protection in Cloud Hosting

When you host your domains in a cloud hosting account with us and we manage the e-mails for them, you are able to activate SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service can be found in its own section where you're able to see which domains are already secured. For those which aren't, you'll be able to enable the SPF protection service and configure a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and even to create a rule that emails can be sent only when your domains include our MX records. The aforementioned choice is the most secure one, but you can use it when we take care of the e-mails for your domain names and do not use some other e-mail service provider. The new records will propagate within a day and nobody will be able to fake the FROM field in an e-mail by using your email addresses.
