SPF, which is an acronym for Sender Policy Framework, is an email protection system, that is employed to confirm whether an email message is sent by a licensed server. Using SPF protection for a particular domain will prevent the forging of email addresses created with the domain. In layman's terms: activating this function for a domain creates a special record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send email messages from mail boxes under the domain. Once this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. Whenever a new email message is sent, the first DNS server it uses checks if it comes from an accredited server. In the event it does, it's forwarded to the destination address, yet when it doesn't come from a server indexed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an email address then make it appear as if you're e-mailing spam messages. This technique is also referred to as email spoofing.

SPF Protection in Cloud Hosting

If you host your domains in a cloud hosting account on our end and we handle the emails for them, you'll be able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you'll be able to see which domain names are currently protected. For the ones that aren't, you will be able to 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 e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that email messages can be sent only when your domain names have our MX records. The last mentioned option is the most secure one, but it can be used if we take care of the email addresses for your domain names and you are not using a different e-mail provider. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in a message with your email addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account with us, you are able to secure your emails by enabling the SPF security service for every domain name hosted in your account with just a couple of mouse-clicks. This is done through the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of issues, you won't have any kind of trouble to enable the security. All that you'll have to do will be to select a domain name from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be mailed around the world only if they're sent from that particular server. In case your emails are taken care of by us and not by a third-party supplier, you will also be able to take advantage of an option for email messages to be sent only when the domain contains our MX records and this would be the safest option. Should you have any questions related to thisfunction, you can get in touch with our support crew 24/7.
