SPF, which means Sender Policy Framework, is an email security system, which is employed to verify if an e-mail message is sent by an official server. Employing SPF protection for a given domain name will stop the forging of emails created with the domain. In simple words: activating this function for a domain name creates a special record in the Domain Name System (DNS) that contains the IP of the servers which are permitted to send e-mail messages from mail boxes using the domain. As soon as this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Whenever some email message is sent, the first DNS server it goes through tests if it originates from an authorized server. In the event it does, it's forwarded to the destination address, but when it doesn't come from a server listed in the SPF record for the domain, it's discarded. In this way nobody will be able to mask an e-mail address then make it appear as if you're e-mailing spam messages. This method is also known as email spoofing.
SPF Protection in Shared Website Hosting
SPF protection can be enabled for every domain hosted in a shared website hosting account on our cloud hosting platform with only a couple of mouse-clicks. The feature is available in the Emails section of our hi-tech Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down menu and then enter the hostnames plus the IPv4 or IPv6 addresses of the email servers that will be approved to send email messages from your email addresses. As an additional option you can also restrict the messages to be sent from your domain name only if it has our MX records, i.e. when our servers manage the emails for it, not some third-party provider. This option provides you with the highest standard of protection, but it's not applicable when only your web site is on our servers while your email addresses for the domain are managed somewhere else. Either way, the SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
The Hepsia website hosting Control Panel, which is provided with all our Linux semi-dedicated servers, provides you with an incredibly user-friendly interface to enable the SPF protection service for any domain name that you host within your new account. Several clicks in the Emails section of Hepsia will be enough for that and you'll only have to enter the hostname and the IP address of the mail server that will be allowed to send out messages from your e-mails. In case the e-mails are managed on our end and not by some other supplier, you'll be able to raise the security level even more and activate an option for your outgoing e-mail messages to be sent only if your domains feature our MX records. This option will give you more control and it'll eliminate any chance of somebody forging your email addresses with the intention of spamming or scamming people. It's not applicable if just your website is on our modern cloud website hosting platform, while your e-mail addresses are managed by some other service provider. If you aren't sure what options to pick, our tech support team will help you 24/7.
