SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, which is used to verify if an e-mail message was sent by an authorized server. Employing SPF protection for a domain name will prevent the faking of email addresses created with the domain. In simple words: activating this function for a domain name makes a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send e-mail messages from mail boxes using the domain. As soon as this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Every time some e-mail message is sent, the initial DNS server it goes through tests whether it originates from an approved server. In the event it does, it is sent to the destination address, but if it doesn't come from a server indexed in the SPF record for the particular domain, it is rejected. Thus nobody will be able to mask an email address to make it look as if you're e-mailing spam. This technique is also referred to as email spoofing.

SPF Protection in Shared Hosting

SPF protection can be enabled for any domain hosted in a shared hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The feature can be found in the Emails section of our amazing Hepsia Control Panel and what is needed to enable it is to select one of your domains from the drop-down menu and then enter the hostnames and the IPv4 or IPv6 addresses of the email servers which will be approved to send email messages from your emails. As an additional option you can even restrict the messages to be sent from your domain only if it includes our MX records, i.e. if our servers handle the email addresses for it, not a third-party provider. This solution will give you the highest level of protection, but it's not applicable in case only your website is on our servers while the emails for the domain name are handled in another place. Either way, our SPF protection service will keep your email addresses secure from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Hosting

If you host your domain names in a semi-dedicated server account with us, you can use the SPF protection feature as a part of the conventional group of services that you'll get with this kind of web hosting. Starting the protection requires just a couple of easy steps within the Hepsia Control Panel, therefore even in the event that you've never employed this type of function before, you won't have any kind of problems. Using a very intuitive interface, you will just have to insert the information of the mail server that will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently generated record propagates, nobody will be able to fake any e-mail for that particular domain name and send out email messages from a server other than the one you have typed in. This does not specifically have to be our mail server, still in case we manage your emails, you'll be able to allow one more level of security by selecting an option that e-mails can be send out from addresses @your-domain.com only if the domain uses our MX records. Our technical support team can help you 24/7 if you have any kind of questions about this service.
