Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an email message can be sent from one address, but to appear as being sent from a different one, often with the purpose to scam the recipient for some reason. When SPF protection is enabled for a domain, a unique record is created for it in the Domain Name System and all of the DNS servers worldwide receive it. The record features all of the e-mail servers that are permitted to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is authorized, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the given domain, the message won't be submitted and it'll be removed. If you employ this service, it will stop third parties from sending spam which seem to have been sent by you.

SPF Protection in Shared Web Hosting

You can activate the SPF protection service for your domains with a couple of clicks inside the Hepsia Control Panel, which is provided with all of our Linux shared web hosting. This is performed from the section with the same name and you can allow the protection for any domain hosted on our innovative cloud hosting platform. Using a really simple interface, all you need to submit is the hostname of the mail server which will be approved to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you are able to add several servers too, when needed. If your emails are taken care of by us, you can also use an even more secure option by putting a limit that messages can be sent only if your domains include our MX records. This solution can't be applied if your web site is here, and the email addresses are with some third-party supplier. Either way, the SPF protection solution can vastly improve your web protection and stop others from forging your e-mail addresses.
