SPF, which is short for Sender Policy Framework, is an email protection system, that is used to validate if an email message was sent by a certified server. Employing SPF protection for a particular domain name will stop the counterfeiting of emails made with the domain. In layman's terms: enabling this attribute for a domain makes a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send e-mails from mail boxes under the domain. When this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Whenever a new e-mail message is sent, the initial DNS server it uses checks if it comes from an authorized server. When it does, it's forwarded to the destination address, but if it doesn't come from a server part of the SPF record for the domain, it's rejected. Thus nobody will be able to mask an e-mail address to make it appear as if you're distributing spam messages. This method is also called email spoofing.
SPF Protection in Cloud Hosting
You'll be able to activate the SPF protection option for your domains with a few clicks inside the Hepsia Control Panel, which is included with all of our Linux cloud packages. This is done from the section bearing the very same name and you're able to enable the protection for each and every domain on our state-of-the-art cloud hosting platform. Using a really time and effort saving interface, all you'll need to submit is the hostname of the mail server which will be approved to send out messages from your emails and its IPv4 or IPv6 address. Of course, it is possible to add several servers as well, if needed. If your e-mail addresses are managed by us, you can also take advantage of an even more secure option by placing a limit that messages can be sent only if your domain names have our MX records. This option cannot be applied if your website is hosted with us, and the emails are with some third-party provider. In either case, the SPF protection option will tremendously enhance your web safety and stop others from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account from us, you will be able to use the SPF protection feature as a part of the conventional set of services that you will have with this kind of web hosting. Starting the protection involves only a few simple steps inside the Hepsia Control Panel, so even if you haven't used such a function before, you will not have any type of problems. Through an exceptionally easy-to-navigate interface, you'll just need to insert the information of the mail server that will be permitted to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently created record propagates, nobody will be able to fake any e-mail address for that particular domain and send messages from a server other than the one you have entered. This doesn't specifically have to be our mail server, however in case we handle your e-mails, you're able to allow an additional level of security by choosing an option that emails can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our technical support team can assist you 24/7 in case you have any kind of questions related to this service.
