SPF, which means Sender Policy Framework, is an email security system, which is used to validate if an e-mail message was sent by a certified server. Employing SPF protection for a given domain will stop the counterfeiting of email addresses generated with the domain. In layman's terms: enabling this attribute for a domain generates a specific record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send e-mail messages from mailboxes under the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Any time an email message is sent, the initial DNS server it uses verifies whether it originates from an approved server. In the event it does, it is forwarded to the destination address, however if it does not originate from a server indexed in the SPF record for the domain, it is discarded. Thus nobody will mask an e-mail address and make it look as if you're sending spam messages. This method is also termed email spoofing.
SPF Protection in Website Hosting
You can activate the SPF protection service for your domains with only a few clicks inside the Hepsia Control Panel, which is included in all our Linux website hosting. This is performed from the section with an identical name and you can allow the protection for each and every domain part of our leading-edge cloud hosting platform. Using a really time and effort saving interface, all you need to submit is the hostname of the mail server which will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, when needed. When your emails are handled on our end, you can also employ an even more secure option by setting a limit that e-mail messages can be sent only when your domain names have our MX records. This alternative cannot be used in case your web site is hosted with us, but the email addresses are with a third-party service provider. In either case, the SPF protection solution can greatly increase your online security and prevent other people from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you host your domain names in a semi-dedicated server account from us, you'll be able to use the SPF protection feature as part of the regular collection of services that you'll get using this type of website hosting. Activating the protection will involve just several easy steps within the Hepsia Control Panel, so that even in case you have never used this type of function before, you won't have any type of issues. Using an exceptionally easy-to-navigate interface, you'll simply have to enter the information of the mail server which will be permitted to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently made record propagates, no one will be able to fake any email for that particular domain and send emails from a server other than the one you've entered. This doesn't specifically have to be our mail server, however in case we take care of your e-mails, you are able to allow one more level of protection by choosing an option that email messages can be send from addresses @your-domain.com only in case the domain uses our MX records. Our tech support team can help you 24/7 in case you have any questions regarding this service.
