SPF, which is an acronym for Sender Policy Framework, is an email safety system, which is employed to verify whether an e-mail message is sent by an authorized server. Employing SPF protection for a domain will stop the faking of email addresses made with the domain. In simple words: activating this feature for a domain makes a particular record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send emails from mail boxes under the domain. The moment this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. When some email message is sent, the first DNS server it goes through tests if it comes from an authorized server. When it does, it is sent to the destination address, however when it does not come from a server listed in the SPF record for the domain, it is discarded. Thus nobody will be able to mask an email address to make it look as if you're sending spam. This approach is also known as email spoofing.

SPF Protection in Cloud Hosting

You'll be able to activate the SPF protection option for your domains with just a few clicks from the Hepsia Control Panel, which is included in all of our Linux cloud hosting. This is done from the section bearing the same name and you can set up the protection for each domain on our innovative cloud hosting platform. Using a very intuitive interface, all you need to type in is the hostname of the mail server that will be approved to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, it is possible to add several servers as well, if needed. In case your email addresses are taken care of on our end, you may also employ a more risk-free option by setting a restriction that email messages can be sent only if your domain names have our MX records. This option cannot be applied in case your web site is hosted here, but your email addresses are with some third-party service provider. Either way, the SPF protection option can considerably increase your web security and prevent other people from spoofing your email addresses.
