SPF, which stands for Sender Policy Framework, is an email security system, that is used to verify if an email message is sent by a certified server. Employing SPF protection for a domain name will stop the forging of email addresses created with the domain. In layman's terms: activating this feature for a domain name creates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers that are permitted to send email messages from mailboxes using the domain. The moment this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When an email message is sent, the initial DNS server it uses tests if it originates from an authorized server. In the event it does, it's forwarded to the destination address, however if it does not come from a server part of the SPF record for the domain, it's rejected. In this way nobody can mask an e-mail address then make it appear as if you're e-mailing spam messages. This approach is also termed email spoofing.
SPF Protection in Cloud Hosting
When you host your domains in a cloud hosting account with us and we handle the e-mails for them, you are able to activate SPF protection for 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 domain names are already protected. For those that are not, you can activate the SPF protection option and set up a variety of things during the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of these servers, and even to create a rule that messages can be sent only if your domain names use our MX records. The aforementioned option is the most secure one, but it can be used in the event that we take care of the email addresses for your domain names and you are not using a different email service provider. The new records will be activated within 1 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 Servers
When you host your domain names in a semi-dedicated server account with us, you will be able to use the SPF protection feature as part of the conventional collection of services that you will receive using this type of web hosting. Starting the protection involves just a couple of easy steps within the Hepsia Control Panel, thus even in case you haven't employed this type of function before, you won't have any type of troubles. Employing a very easy to work with interface, you'll simply need to insert 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). Once the recently created record propagates, no one will be able to forge any e-mail for that particular domain name and send e-mail messages from a server other than the one you have typed in. This does not specifically have to be our mail server, still when we take care of your e-mails, you're able to activate an extra level of protection by picking an option that e-mails can be send from addresses @your-domain.com only in the event that the domain employs our MX records. Our technical support staff will be able to help you 24/7 if you have any questions regarding this service.
