SPF, which means Sender Policy Framework, is an email protection system, which is employed to confirm if an e-mail message is sent by an authorized server. Using SPF protection for a given domain name will prevent the forging of email addresses made with the domain. In layman's terms: enabling this function for a domain name creates a particular record in the Domain Name System (DNS) which contains the IP of the servers that are allowed to send e-mail messages from mailboxes under the domain. Once this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When a new email message is sent, the first DNS server it goes through tests whether it comes from an accredited server. When it does, it is forwarded to the destination address, but when it doesn't come from a server listed in the SPF record for the domain, it's discarded. Thus nobody can mask an e-mail address and make it appear as if you're sending spam messages. This technique is also known as email spoofing.
SPF Protection in Shared Hosting
You'll be able to enable the SPF protection service for your domain names with just a couple of clicks inside the Hepsia Control Panel, which comes with all of our Linux shared hosting packages. This is done via the section bearing the very same name and you're able to enable the protection for each and every domain part of our leading-edge cloud platform. Using a really simple interface, all you will have to submit 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'll be able to add several servers too, if needed. If your e-mail addresses are managed on our end, you may also take advantage of a more secure option by placing a restriction that e-mail messages can be sent only when your domain names feature our MX records. This solution can't be applied in case your site is hosted with us, and your e-mail addresses are with a third-party supplier. In either case, the SPF protection option can greatly increase your online safety and prevent others from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account with us, you can take advantage of the SPF protection feature as a part of the conventional collection of services that you'll get with this kind of hosting. Enabling the protection will involve only several simple steps within the Hepsia Control Panel, thus even if you haven't employed this type of feature before, you won't have any kind of troubles. Through a really easy to work with interface, you will simply have to type in the info of the mail server which will be permitted to send out messages from your 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 name and send out messages from a server other than the one you have entered. This doesn't necessarily have to be our mail server, yet if we manage your email messages, you'll be able to enable an additional level of protection by choosing an option that e-mails can be send from addresses @your-domain.com only in case the domain employs our MX records. Our tech support team can assist you 24/7 in case you have any kind of questions about this service.
