Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different, generally with the purpose to fraud the recipient for some reason. If SPF protection is enabled for a domain name, a specific record is generated for it in the Domain Name System and all of the DNS servers globally get it. The record contains all e-mail servers that are allowed to send authentic messages from an email address within the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is sent to the targeted destination. When, however, the sending server is not included in the SPF record for the given domain, the e-mail message will not be forwarded and it will be removed. In case you use this service, it will prevent third parties from sending spam which appear to have been sent by you.

SPF Protection in Hosting

When you host your domain names in a hosting account on our end and we manage the email addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. The service can be found in a section of its own where you're able to see which domain names are already secured. For the ones that aren't, you can enable the SPF protection option and configure various things during this 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 set a rule that emails can be sent only when your domain names have our MX records. The aforementioned option is the most secure one, and you can use it in the event that we take care of the emails for your domain names and you are not using another email service provider. The newly generated records will propagate within one day and nobody will be able to fake the FROM field in an email using your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account with us, you will be able to protect your emails by enabling the SPF protection service for any domain name in your account with only a few mouse-clicks. You can do this through the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of things, you will not have any difficulties to activate the security. Everything that you will have to do is to find a domain from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your email addresses will be delivered globally only if they are sent from that particular server. If your email addresses are managed by our company and not by some third-party supplier, you will also be able to take advantage of an option for e-mail messages to be mailed only if the domain features our MX records and this is the safest option. If you have any kind of questions regarding thisfeature, you will be able to get in touch with our tech support crew 24/7.
