SPF, which is short for Sender Policy Framework, is an e-mail protection system, that is is intended to confirm if an email message was sent by an authorized server. Using SPF protection for a given domain will prevent the forging of emails generated with the domain. In simple words: enabling this attribute for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send e-mails from mail boxes under the domain. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Every time some e-mail message is sent, the first DNS server it goes through checks if it originates from an accredited server. In the event it does, it's forwarded to the destination address, but if it doesn't come from a server indexed in the SPF record for the particular domain, it is discarded. In this way nobody will mask an email address then make it appear as if you're e-mailing spam messages. This technique is also called email spoofing.

SPF Protection in Shared Hosting

SPF protection can be activated for each domain name hosted in a shared hosting account on our cloud hosting platform with just a few mouse-clicks. The function is available in the Emails section of our modern Hepsia Control Panel and what is needed to enable it is to select one of your domain names from the drop-down menu and enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers which 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 if it has our MX records, i.e. if our servers handle the emails for it, not some third-party provider. This option offers you the highest standard of security, but it is not applicable if only your web site is on our servers while your e-mail addresses for the domain name are managed in a different place. In either case, our SPF protection service will keep your emails protected from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Hosting

If you host your domains in a semi-dedicated server account with us, you are able to take advantage of the SPF protection feature as part of the regular collection of services that you'll get using this kind of hosting. Starting the protection involves only a few simple steps within the Hepsia Control Panel, so even in case you have never employed this type of function before, you won't have any troubles. Using a really intuitive interface, you will only have to input the info of the mail server which 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 recently created record propagates, no one will be able to forge any email for that particular domain and send out e-mail messages from a server other than the one you have entered. This doesn't necessarily have to be our mail server, however in case we take care of your e-mails, you are able to enable one more level of protection by selecting an option that e-mail messages can be send out from addresses @your-domain.com only in the event that the domain uses our MX records. Our tech support crew can assist you 24/7 if you have any questions related to this service.
