SPF, which is an acronym for Sender Policy Framework, is an email security system, which is designed to validate whether an email message is sent by a certified server. Employing SPF protection for a given domain will prevent the forging of email addresses generated with the domain. In layman's terms: activating this attribute for a domain name makes a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mailboxes under the domain. Once this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the initial DNS server it goes through tests whether it comes from an official server. If it does, it's forwarded to the destination address, yet when it does not originate from a server part of the SPF record for the domain, it is rejected. Thus nobody will mask an e-mail address then make it appear as if you are sending spam. This approach is also known as email spoofing.

SPF Protection in Cloud Web Hosting

When you host your domains in a cloud web hosting account with us and we manage the emails for them, you will be able to enable SPF protection for any of them with a couple of clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you will be able to see which domain names are currently secured. For those that aren't, you will be able to activate the SPF protection option and manage a lot of things during this process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domain names use our MX records. The last mentioned choice is the most secure one, and it can be used if we handle the e-mails for your domains and do not use a different e-mail provider. The newly generated records will be activated within 1 day and nobody will be able to fake the FROM field in a message with your email addresses.

SPF Protection in Semi-dedicated Servers

The Hepsia hosting Control Panel, that comes as standard with all our semi-dedicated servers, provides you with a very user-friendly interface to activate the SPF protection service for any domain that you host in your new account. A few clicks in the Emails section of Hepsia are enough for that then you'll only have to type in the hostname and the IP address of the mail server that will be allowed to send out messages from your email addresses. In case the e-mails are taken care of by us and not by some other supplier, you can boost the security level even further and enable an option for all the outgoing e-mails to be sent only if your domains include our MX records. This option will give you better control and it'll eliminate any chance of anyone counterfeiting your e-mail addresses with the objective of spamming and / or scamming people. It is not applicable if just your web site is hosted on our advanced cloud web hosting platform, while your e-mails are handled by another provider. If you are not sure what options to select, our technical support staff will help you 24/7.
