Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to look as being sent from a different, usually with the objective 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 of the DNS servers globally have it. The record features all e-mail servers that are allowed to send legitimate messages from an e-mail address part of the domain. When a message 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 target destination. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be sent and it will be removed. In the event that you use this service, it'll prevent third parties from sending spam which look as if they have been sent by you.

SPF Protection in Cloud Hosting

You'll be able to enable the SPF protection service for your domain names with just a few clicks in the Hepsia Control Panel, which is provided with our Linux cloud packages. This carried out through the section bearing the very same name and you are able to set up the protection for each domain name part of our exceptional cloud hosting platform. Using a really simple interface, all you'll have to enter is the hostname of the mail server that will be approved to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you'll be able to include several servers as well, when needed. In case your e-mail addresses are taken care of on our end, you may also take advantage of a more risk-free option by putting a restriction that e-mail messages can be sent only when your domain names have our MX records. This option cannot be applied in case your site is here, but the e-mail addresses are with some third-party supplier. Either way, the SPF protection option will tremendously increase your online safety and prevent others from forging your email addresses.
