SPF, which means Sender Policy Framework, is an e-mail protection system, that is designed to confirm whether an e-mail message was sent by an official server. Using SPF protection for a given domain will prevent the faking of email addresses made with the domain. In simple words: enabling this function for a domain makes a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send emails from mailboxes under the domain. As soon as this record propagates worldwide, it exists on all DNS servers that direct the Internet traffic. Whenever an email message is sent, the initial DNS server it uses verifies if it comes from an official server. When it does, it is sent to the destination address, yet when it does not come from a server listed in the SPF record for the domain, it's rejected. Thus nobody will mask an e-mail address to make it look as if you're sending spam. This approach is also identified as email spoofing.
SPF Protection in Website Hosting
You are able to activate the SPF protection service for your domains with a few clicks from the Hepsia Control Panel, which is included with our Linux website hosting. This is performed from the section bearing the same name and you're able to set up the protection for each domain part of our outstanding cloud platform. Using a very simple interface, all you will have to enter is the hostname of the mail server which will be authorized to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers too, when needed. When your e-mails are handled by us, you can also use a more risk-free option by placing a limit that emails can be sent only if your domains feature our MX records. This alternative can't be applied in case your web site is hosted with us, and your emails are with a third-party service provider. Either way, the SPF protection option can vastly improve your web security and prevent other people from forging 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 can take advantage of the SPF protection feature as a part of the conventional group of services that you will get with this kind of web hosting. Starting the protection involves only several easy steps in the Hepsia Control Panel, thus even in the event that you have never used this type of feature before, you will not have any type of issues. Using a very easy-to-use interface, you will simply have to type in the information of the mail server which will be certified to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently made record propagates, nobody will be able to counterfeit any email address for that particular domain and send email messages from a server different from the one you have entered. This does not specifically have to be our mail server, but in case we manage your e-mails, you'll be able to enable one more level of security by choosing an option that e-mails can be send from addresses @your-domain.com only in case the domain uses our MX records. Our tech support staff will be able to help you 24/7 if you have any questions related to this service.
