SPF, which means Sender Policy Framework, is an e-mail security system, that is employed to confirm if an email message is sent by an official server. Using SPF protection for a particular domain will prevent the counterfeiting of email addresses made with the domain. In layman's terms: enabling this attribute for a domain makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send e-mails from mail boxes using the domain. As soon as this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When some email message is sent, the initial DNS server it uses tests if it originates from an approved server. In the event it does, it's forwarded to the destination address, but if it does not originate from a server indexed in the SPF record for the particular domain, it is rejected. Thus nobody can mask an email address and make it appear as if you are sending spam messages. This technique is also referred to as email spoofing.
SPF Protection in Shared Hosting
The SPF protection function is provided by default with each and every shared hosting plan that we supply and you can use it with ease to secure the email addresses for each domain name hosted within your account. The service is managed through the Emails section of our hi-tech, yet easy to work with Hepsia Control Panel. All it takes to enable the protection is to type the IP of the mail server and its hostname - mail.server.com, for instance. The moment the protection is active, only this server will be able to send out messages from email addresses created under the domain that you have selected. Your e-mail addresses may be taken care of by a different supplier, but in case that we take care of them in addition to your site, you may also activate the option for your emails to be sent only when the domain uses our MX records. This selection provides you with superior protection as exclusively our server will be authorized to send out e-mail messages from your mailboxes and you will have improved control. When you have any kind of questions or if you have any sort of troubles with this particular service, you will be able to contact our tech support crew anytime and they will help you without delay.
SPF Protection in Semi-dedicated Servers
The SPF protection feature is featured with all the Linux semi-dedicated service, so when you host your domain names in an account on our cloud website hosting platform, you can use the service effortlessly for any of your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a quite intuitive interface, therefore you do not need to be proficient in the use of computers in order to secure your e-mail addresses. You'll only need to type the hostname and the IP address of each mail server that you would like to be permitted to send out e-mails from your addresses and right after that the updated record will be activated for the domain name that you've picked. As an additional option, we will also allow you to restrict the outgoing e-mail messages and secure your mailboxes even further by allowing emails to be sent only if the domain in question features our MX records i.e. the e-mail messages for the domain should be handled by us and not by another provider. By doing this you will enjoy even better control and there won't be any chance for somebody to counterfeit your emails for harmful activities.
