Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different one, usually with the idea to fraud the recipient someway. When SPF protection is enabled for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers worldwide receive it. The record includes all the email servers that are permitted to send legitimate messages from an email address part of the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and in case its sending server is permitted, the message is forwarded to the target destination. When, however, the sending server doesn't exist in the SPF record for the given domain, the message will not be sent and it will be removed. In the event that you use this solution, it'll stop third parties from sending spam messages that appear to have been sent from you.

SPF Protection in Web Hosting

You'll be able to enable the SPF protection option for your domains with just a few clicks from the Hepsia Control Panel, which comes with our Linux web hosting packages. This carried out from the section with the same name and you'll be able to allow the protection for any domain part of our revolutionary cloud platform. Using a very simple interface, all you will have to type in is the hostname of the mail server that will be accredited to send messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers as well, if needed. If your e-mail addresses are handled on our end, you can also employ an even more risk-free option by setting a restriction that e-mail messages can be sent only when your domains feature our MX records. This solution cannot be used in case your site is hosted here, while your e-mail addresses are with some third-party supplier. In either case, the SPF protection solution will vastly enhance your web safety and prevent other people 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 standard group of services that you will get using this type of web hosting. Activating the protection involves just a couple of easy steps within the Hepsia Control Panel, therefore even if you haven't employed such a function before, you won't have any type of problems. Using a really easy-to-navigate interface, you'll just have to insert the information of the mail server which will be permitted to send messages from your addresses - its hostname ( and IP address (IPv4 or IPv6). As soon as the recently made record propagates, no one will be able to fake any email address for that particular domain name and send messages from a server other than the one you have typed in. This does not specifically have to be our mail server, but if we manage your emails, you'll be able to allow an extra level of security by selecting an option that emails can be send out from addresses only in the event that the domain uses our MX records. Our tech support team can assist you 24/7 if you have any kind of questions about this service.
