Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called email spoofing where an e-mail message is sent from one email, but to seem as being sent from a different, generally with the idea to fraud the recipient in some way. When SPF protection is enabled for a domain, an exclusive record is created for it in the Domain Name System and all of the DNS servers globally get it. The record features all e-mail servers that are permitted to send authentic messages from an address under the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted receiver. In case, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be forwarded and it will be removed. In case you employ this service, it will prevent third parties from sending spam messages that look as if they have been sent from you.

SPF Protection in Web Hosting

When you host your domain names in a web hosting account with us and we handle the emails for them, you'll be able to activate SPF protection for all of them with several clicks in your Hepsia Control Panel. This service can be found in a section of its own where you'll be able to view which domains are already protected. For those that aren't, you will be able to enable the SPF protection option and set up a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that emails can be sent only when your domains include our MX records. The last option is the most secure one, and you can use it when we handle the e-mails for your domain names and you are not using a different e-mail service provider. The newly generated records will propagate within one day and nobody will be able to fake the FROM field in an email by using your email addresses.

SPF Protection in Semi-dedicated Servers

When you host your domain names in a semi-dedicated server account with our company, you will be able to take advantage of the SPF protection feature as part of the regular collection of services that you'll get using this type of hosting. Starting the protection will involve just a couple of simple steps in the Hepsia Control Panel, thus even in the event that you haven't used this kind of feature before, you won't have any type of problems. Employing an exceptionally intuitive interface, you'll just need to enter the details of the mail server which will be certified to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly made record propagates, no one will be able to fake any e-mail address for that particular domain name and send emails from a server different from the one you have typed in. This doesn't specifically have to be our mail server, however when we manage your email messages, you can allow an additional level of security by picking an option that email messages can be send from addresses @your-domain.com only in the event that the domain uses our MX records. Our tech support staff will be able to help you 24/7 if you have any questions about this service.
