SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, which is designed to validate whether an email message was sent by a licensed server. Using SPF protection for a given domain name will prevent the forging of emails generated with the domain. In layman's terms: activating this attribute for a domain name creates a special record in the Domain Name System (DNS) that contains the IP addresses of the servers which are permitted to send e-mail messages from mail boxes using the domain. As soon as this record propagates globally, it will exist on all of the DNS servers that direct the Internet traffic. Any time some e-mail message is sent, the first DNS server it goes through verifies if it comes from an accredited server. In the event it does, it's forwarded to the destination address, yet when it doesn't come from a server part of the SPF record for the domain, it's rejected. In this way nobody will be able to mask an e-mail address to make it look as if you are distributing spam messages. This method is also known as email spoofing.
SPF Protection in Cloud Website Hosting
You are able to activate the SPF protection service for your domains with only a few clicks in the Hepsia Control Panel, which is provided with all of our Linux cloud website hosting packages. This is done from the section bearing the very same name and you are able to allow the protection for each and every domain name part of our revolutionary cloud hosting platform. Using a really user-friendly interface, all you will need to type in is the hostname of the mail server that will be permitted to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you're able to include several servers too, when needed. If your emails are taken care of by us, you can also employ an even more secure option by setting a restriction that messages can be sent only if your domains include our MX records. This alternative cannot be applied if your web site is hosted with us, and your emails are with a third-party provider. In either case, the SPF protection option can tremendously improve your online safety and prevent others from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
If you host your domain names in a semi-dedicated server account with us, you will be able to use the SPF protection feature as a part of the standard collection of services that you will receive using this type of web hosting. Enabling the protection will require just a few simple steps in the Hepsia Control Panel, so that even when you have never employed such a feature before, you will not have any troubles. Using a really easy-to-navigate interface, you'll simply have to insert the details of the mail server that will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently made record propagates, nobody will be able to fake any e-mail for that particular domain name and send out emails from a server other than the one you've entered. This does not specifically have to be our mail server, yet in case we take care of your email messages, you'll be able to allow one more level of security by selecting an option that e-mails can be send from addresses @your-domain.com only if the domain uses our MX records. Our technical support crew can assist you 24/7 if you have any kind of questions about this service.
