Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an email message is sent from one e-mail address, but to seem as being sent from a different, generally with the purpose to fraud the recipient for some reason. When SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all the DNS servers globally have it. The record contains all the email servers that are allowed to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case the sending server is authorized, the message is sent to the targeted destination. When, however, the sending server is not present in the SPF record for the specified domain, the message won't be forwarded and it will be discarded. Whenever you employ this service, it will stop third parties from sending spam that seem to have been sent by you.

SPF Protection in Shared Hosting

If you host your domain names in a shared hosting account on our end and we manage the e-mail addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service is available in its own section where you are able to see which domains are currently protected. For those which aren't, you can activate the SPF protection service and set up numerous 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 the servers, and to create a rule that email messages can be sent only if your domains have our MX records. The aforementioned choice is the most secure one, but you can use it in the event that we manage the emails for your domain names and do not use a different e-mail supplier. The newly generated records will be activated within one day and nobody will be able to fake the FROM field in an email using your email addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from our company, you can protect your emails by enabling the SPF protection service for any domain hosted in the account with just a couple of mouse-clicks. This can be done through the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous experience with these kinds of issues, you won't have any kind of troubles to enable the security. All that you'll need to do will be to select a domain from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be delivered globally only if they are sent from that specific server. In case your e-mail addresses are handled by us and not by some third-party supplier, you'll also be able to activate an option for emails to be sent only if the domain name includes our MX records and this would be the safest option. In case you have any questions related to thisfeature, you will be able to get in touch with our technical support crew 24/7.
