Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called email spoofing where an e-mail message is sent from one e-mail address, but to seem as being sent from a different one, generally with the purpose to fraud the recipient in some way. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all of the email servers that are permitted to send authentic messages from an e-mail address part of the domain. When a message is sent, the first DNS server it goes to checks the SPF record and in case the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server is not contained in the SPF record for the specified domain, the email message won't be submitted and it'll be removed. If you use this service, it will prevent third parties from sending spam that seem to have been sent from you.

SPF Protection in Shared Website Hosting

SPF protection can be enabled for any domain name hosted in a shared website hosting account on our cloud platform with no more than a few mouse-clicks. The feature is accessible in the Emails section of our modern Hepsia Control Panel and all it takes to enable it is to pick one of your domains from a drop-down menu and type in the hostnames along with the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send messages from your emails. As an added option you can even restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. if our servers handle the e-mail addresses for it, not some third-party provider. This feature provides you with the highest standard of protection, but it is not applicable when only your site is on our servers while the email addresses for the domain name are taken care of in a different place. Regardless, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Hosting

When you host your domains in a semi-dedicated server account from our company, you'll be able to benefit from the SPF protection feature as a part of the conventional collection of services that you will get with this kind of website hosting. Starting the protection requires just a couple of simple steps within the Hepsia Control Panel, so that even in case you haven't used such a function before, you will not have any kind of troubles. Using a very time and effort saving interface, you'll only have to input the details of the mail server that will be permitted to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly created record propagates, nobody will be able to counterfeit any email for that particular domain and send out emails from a server other than the one you've entered. This doesn't necessarily have to be our mail server, yet if we handle your email messages, you can enable an extra level of security by picking an option that e-mails can be send out from addresses @your-domain.com only if the domain employs our MX records. Our technical support staff will be able to assist you 24/7 in case you have any kind of questions related to this service.
