SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is used to validate if an e-mail message was sent by an authorized server. Employing SPF protection for a domain will prevent the faking of emails generated with the domain. In simple words: enabling this feature for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP of the servers which are allowed to send e-mail messages from mail boxes under the domain. Once this record propagates globally, it exists on all the DNS servers that route the Internet traffic. When a new e-mail message is sent, the initial DNS server it uses checks whether it originates from an approved server. When it does, it's forwarded to the destination address, however when it does not come from a server listed in the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an email address and make it look as if you're sending spam messages. This technique is also referred to as email spoofing.

SPF Protection in Website Hosting

You're able to enable the SPF protection option for your domains with just a couple of clicks in the Hepsia Control Panel, which is included in all our Linux website hosting. This is performed from the section bearing the very same name and you are able to enable the protection for each domain part of our revolutionary cloud hosting platform. Using a really intuitive interface, all you have to enter is the hostname of the mail server that will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you're able to include several servers too, if needed. When your e-mail addresses are managed on our end, you can also use an even more risk-free option by putting a restriction that email messages can be sent only if your domains feature our MX records. This alternative can't be applied in case your website is hosted here, and your emails are with a third-party supplier. In either case, the SPF protection option can vastly enhance your web security and stop other people from forging your email addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from our company, you can secure your email addresses by activating the SPF protection service for any domain name in the account with just a few mouse-clicks. You can do this through the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous practical experience with these matters, you will not have any kind of trouble to activate the security. The only things that you'll have to do is to choose a domain from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your e-mail addresses will be delivered around the world only if they are sent from that specific server. When your email addresses are taken care of by us and not by a third-party supplier, you'll also be able to benefit from an option for e-mail messages to be mailed only when the domain has our MX records and the aforementioned would be the safest option. If you have any questions related to thisfeature, you will be able to contact our technical support crew 24/7.
