SPF, which is an acronym for Sender Policy Framework, is an email security system, which is used to verify if an e-mail message is sent by an official server. Using SPF protection for a given domain will stop the faking of email addresses created with the domain. In layman's terms: activating this feature 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 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 initial DNS server it goes through checks if it originates from an authorized server. If it does, it is forwarded to the destination address, but when it doesn't originate from a server indexed in the SPF record for the domain, it's discarded. In this way nobody can mask an e-mail address to make it look as if you're e-mailing spam messages. This technique is also identified as email spoofing.
SPF Protection in Web Hosting
When you host your domain names in a web hosting account with us and we manage the e-mails for them, you'll be able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service can be found in its own section where you can see which domains are already secured. For the ones that aren't, you can activate the SPF protection solution and configure a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that email messages can be sent only when your domains have our MX records. The aforementioned option is the most secure one, but it can be used if we take care of the e-mail addresses for your domain names and you're not using a different email provider. The new records will propagate within a day and nobody will be able to fake the FROM field in an e-mail by using 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 a part of the conventional group of services that you will receive with this kind of hosting. Starting the protection will involve just several simple steps in the Hepsia Control Panel, therefore even when you haven't used this type of function before, you will not have any kind of issues. Through an exceptionally easy-to-navigate interface, you'll only have to type in the details of the mail server which will be authorized to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly made record propagates, no one will be able to counterfeit any email for that particular domain name and send out e-mail messages from a server different from the one you have typed in. This does not necessarily have to be our mail server, but in case we handle your email messages, you can activate an additional level of protection by choosing 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 crew will be able to assist you 24/7 if you have any questions related to this service.
