Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to look as being sent from another, generally with the purpose to fraud the recipient in some way. If SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all of the DNS servers worldwide have it. The record contains all of the email servers that are allowed to send authentic messages from an e-mail address part of the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and when its sending server is authorized, the message is sent to the targeted receiver. In case, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message will not be forwarded and it will be discarded. When you use this solution, it will stop third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Shared Hosting

You can activate the SPF protection service for your domains with just a couple of clicks inside the Hepsia Control Panel, which comes with all our shared plans. This is done from the section with the very same name and you can allow the protection for any domain name hosted on our exceptional cloud hosting platform. Using a very user-friendly interface, all you will need to type in is the hostname of the mail server that will be permitted to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, it is possible to include several servers too, if needed. If your emails are handled on our end, you can also use a more secure option by setting a limit that messages can be sent only when your domain names include our MX records. This alternative can't be used in case your web site is hosted with us, while your email addresses are with a third-party service provider. Either way, the SPF protection option will greatly enhance your web protection and prevent other people from counterfeiting your email addresses.
