SPF, which means Sender Policy Framework, is an e-mail security system, which is used to validate whether an email message was sent by an official server. Using SPF protection for a particular domain name will prevent the forging of emails generated with the domain. In layman's terms: activating this function for a domain makes a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers which are permitted to send e-mail messages from mail boxes using the domain. When this record propagates globally, 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 goes through verifies whether it originates from an official server. When it does, it is sent to the destination address, but if it doesn't come from a server listed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an email address and make it look as if you're sending spam messages. This approach is also known as email spoofing.
SPF Protection in Shared Website Hosting
You're able to enable the SPF protection option for your domains with just a couple of clicks inside the Hepsia Control Panel, which is included in all our Linux shared website hosting packages. This is performed from the section bearing the same name and you are able to enable the protection for any domain name hosted on our state-of-the-art cloud platform. Using a very simple interface, all you need to submit is the hostname of the mail server which will be authorized to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, it is possible to add several servers too, when needed. If your emails are taken care of on our end, you can also employ an even more secure option by placing a restriction that messages can be sent only if your domains include our MX records. This option can't be used if your web site is hosted with us, while your e-mail addresses are with a third-party supplier. In either case, the SPF protection solution will really increase your web security and prevent others from spoofing your email addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account with our company, you'll be able to employ the SPF protection feature as a part of the regular collection of services that you'll get with this type of web hosting. Enabling the protection requires just several simple steps inside the Hepsia Control Panel, so even in the event that you have never used this type of function before, you won't have any type of troubles. Through an exceptionally time and effort saving interface, you'll just have to type in the details of the mail server which will be certified to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly created record propagates, no one will be able to counterfeit any email for that particular domain and send out e-mail messages from a server other than the one you have entered. This doesn't necessarily have to be our mail server, still in case we handle your email messages, you're able to activate an additional level of security by selecting an option that emails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our tech support team can help you 24/7 if you have any questions about this service.
