SPF, which is an acronym for Sender Policy Framework, is an email security system, which is is intended to verify if an e-mail message was sent by an authorized server. Employing SPF protection for a given domain will prevent the forging of emails created with the domain. In layman's terms: activating this feature for a domain makes a special record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send emails from mailboxes using the domain. As soon as this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Any time a new e-mail message is sent, the first DNS server it goes through verifies if it comes from an official 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 will mask an e-mail address then make it look as if you're e-mailing spam messages. This method is also referred to as email spoofing.
SPF Protection in Shared Hosting
You'll be able to activate the SPF protection option for your domain names with only a few clicks in the Hepsia Control Panel, which is included with all of our shared hosting. This is done from the section bearing an identical name and you're able to set up the protection for each and every domain on our advanced cloud platform. Using a very simple interface, all you'll have to type in is the hostname of the mail server that will be approved to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you can include several servers as well, when needed. If your email addresses are handled by us, you may also take advantage of a more risk-free option by putting a limit that emails can be sent only when your domains include our MX records. This solution cannot be applied if your site is hosted with us, while your e-mail addresses are with some third-party service provider. In either case, the SPF protection option will tremendously increase your web safety and prevent others from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection attribute comes with all the semi-dedicated servers, so in case you host your domains in an account on our cloud hosting platform, you're able to use this particular service with ease for any of your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a really intuitive interface, which means that you will not need to be tech-savvy to protected your emails. You'll simply need to type the hostname and the IP address of each mail server that you would like to be certified to send out emails from your addresses and right after that the updated record will be activated for the domain that you have chosen. As a further option, we also give you the ability to control your outgoing email messages and protect your mailboxes further by allowing e-mail messages to be sent only when the domain name involved contains our MX records i.e. the email messages for the domain should be handled here and not by a different supplier. Thus you will enjoy even superior control and there won't be a chance for anybody to counterfeit your emails for harmful intentions.
