SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, which is designed to verify whether an e-mail message was sent by a certified server. Employing SPF protection for a domain name will stop the counterfeiting of emails created with the domain. In simple words: enabling this feature for a domain name generates a special record in the Domain Name System (DNS) which includes the IP of the servers that are permitted to send emails from mailboxes using the domain. Once this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. Every time a new e-mail message is sent, the initial DNS server it uses tests whether it originates from an official server. When it does, it is forwarded to the destination address, but when it does not come from a server listed in the SPF record for the domain, it's rejected. In this way nobody can mask an email address then make it look as if you are sending spam messages. This approach is also identified as email spoofing.
SPF Protection in Shared Hosting
When you host your domain names in a shared hosting account on our end and we manage the email addresses for them, you'll be able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you are able to see which domain names are already protected. For those that aren't, you'll be able to activate the SPF protection service and manage various things during this process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that emails can be sent only when your domain names use our MX records. The aforementioned choice is the most secure one, and it can be used when we manage the email addresses for your domains and you are not using some other e-mail service provider. The newly created records will be activated within 1 day and nobody will be able to forge the FROM field in an email with your addresses.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account from us, you are able to secure your email addresses by activating the SPF security service for any domain name hosted in your account with just a couple of clicks. You can do this from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you lack previous practical experience with these issues, you will not have any problems to activate the security. Everything that you will have to do is to pick a domain from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your e-mail addresses will be sent worldwide only if they are sent from that specific server. If your e-mail addresses are managed by us and not by a third-party provider, you can also use an option for emails to be sent only if the domain features our MX records and the latter is the safest option. In case you have any kind of questions about thisfeature, you will be able to get in touch with our technical support team 24/7.
