SPF, which is short for Sender Policy Framework, is an email security system, that is designed to verify if an e-mail message is sent by an authorized server. Employing SPF protection for a domain name will stop the counterfeiting of email addresses created with the domain. In simple words: activating this attribute for a domain name creates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are permitted to send emails from mailboxes using the domain. When this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. Whenever a new email message is sent, the first DNS server it uses checks if it originates from an official server. If it does, it is forwarded to the destination address, but if it does not originate from a server listed in the SPF record for the domain, it's rejected. In this way nobody will be able to mask an email address then make it appear as if you are distributing spam. This method is also called email spoofing.
SPF Protection in Shared Hosting
When you host your domain names in a shared hosting account on our end and we manage the emails for them, you will be able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you can view which domain names are currently secured. For those that are not, you can activate the SPF protection service and configure a lot of things in the process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that messages can be sent only when your domain names use our MX records. The aforementioned choice is the most secure one, but you can use it if we take care of the e-mail addresses for your domain names and you're not using another e-mail supplier. The new records will propagate within a day and nobody will be able to forge the FROM field in an e-mail using your email addresses.
SPF Protection in Semi-dedicated Hosting
The Hepsia hosting Control Panel, which is included with all of our Linux semi-dedicated hosting packages, offers you a very easy-to-use interface to activate the SPF security service for any domain that you host inside your new account. A couple of 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 which will be permitted to send out messages from your e-mails. In case the e-mail messages are taken care of on our end and not by a different supplier, you will be able to increase the protection level even further and benefit from an option for all the outgoing e-mail messages to be sent only if your domains use our MX records. This option provides you with more control and it will eliminate any chance of anybody counterfeiting your e-mails with the purpose of spamming and scamming people. It's not applicable when just your website is hosted on our cutting-edge cloud website hosting platform, while your emails are handled by some other provider. If you aren't sure what options to pick, our tech support crew will assist you 24/7.
