SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is designed to validate whether an e-mail message is sent by a certified server. Using SPF protection for a particular domain will stop the faking of email addresses made with the domain. In simple words: enabling this function for a domain name creates a special record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send email messages from mail boxes under the domain. Once this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. Every time some email message is sent, the first DNS server it goes through verifies whether it originates from an approved server. If it does, it's sent to the destination address, but if it doesn't come from a server listed in the SPF record for the domain, it's rejected. In this way nobody can mask an e-mail address then make it appear as if you are e-mailing spam. This approach is also referred to as email spoofing.

SPF Protection in Shared Web Hosting

SPF protection can be enabled for each domain hosted in a shared web hosting account on our cloud platform with no more than a couple of mouse-clicks. The feature is available in the Emails section of our advanced Hepsia Control Panel and all you need to use it is to pick one of your domains from the drop-down menu and enter the hostnames as well as the IPv4 or IPv6 addresses of the email servers which will be authorized to send email messages from your email addresses. As an additional option you may also restrict the messages to be sent from your domain only when it has our MX records, in other words when our servers handle the email addresses for it, not some third-party supplier. This solution will provide you with the top standard of safety, but it is not applicable in case only your web site is on our servers while the e-mail addresses for the domain are taken care of in a different place. In either case, the SPF protection service will keep your email addresses secure from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Hosting

The SPF protection function is provided with all of the Linux semi-dedicated services, so in case you host your domains in an account on our cloud web hosting platform, you can activate this service without difficulty for all your domain names. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a really easy to use interface, which means that you won't need to be proficient in the use of computers in order to protected your emails. You will only need to type the hostname and the IP address of each mail server that you'd like to be certified to send out e-mails from your addresses and right after that the new record will be active for the domain name that you have picked. As an additional option, we'll also give you the ability to limit your outgoing e-mail messages and secure your mailboxes even better by allowing email messages to be sent only when the domain involved includes our MX records i.e. the email messages for the domain should be taken care of here and not by another supplier. By doing this you will enjoy even better control and there won't be any chance for any person to forge your e-mails for harmful purposes.
