SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is employed to confirm if an e-mail message is sent by an authorized server. Using SPF protection for a given domain name will prevent the counterfeiting of emails created with the domain. In layman's terms: enabling this attribute for a domain name makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers that are allowed to send e-mail messages from mailboxes using the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Any time some e-mail message is sent, the first DNS server it uses tests whether it originates from an accredited server. If it does, it's sent to the destination address, however when it doesn't originate from a server indexed in the SPF record for the particular domain, it's rejected. In this way nobody will be able to mask an email address then make it appear as if you are e-mailing spam. This approach is also identified as email spoofing.

SPF Protection in Cloud Hosting

When you host your domain names in a cloud hosting account on our end and we manage the email addresses for them, you'll be able to activate SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. This service is accessible in a separate section where you are able to see which domain names are currently secured. For those which aren't, you can enable the SPF protection service and set up a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to set a rule that messages can be sent only if your domains have our MX records. The last option is the most secure one, and it can be used when we take care of the e-mails for your domains and you are not using some other e-mail supplier. The newly created records will propagate within one day and nobody will be able to forge the FROM field in an e-mail with your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you host your domains in a semi-dedicated server account with us, you can use the SPF protection feature as part of the regular collection of services that you will have with this type of web hosting. Activating the protection requires only a few easy steps in the Hepsia Control Panel, so even when you have never used such a feature before, you won't have any troubles. Through an exceptionally easy-to-use interface, you will simply have to input the details of the mail server which will be permitted to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly made record propagates, nobody will be able to fake any e-mail for that particular domain name and send out e-mails from a server other than the one you have entered. This doesn't specifically have to be our mail server, yet in case we take care of your emails, you will be able to activate an extra level of security by choosing an option that email messages can be send from addresses @your-domain.com only in case the domain uses our MX records. Our tech support staff can help you 24/7 if you have any questions regarding this service.
