Sender Policy Framework, or SPF, is a validation system, which is used to stop the so-called email spoofing where an e-mail message can be sent from one email address, but to look as being sent from another, generally with the objective to scam the recipient for some reason. If SPF protection is enabled for a domain, an exclusive record is created for it in the Domain Name System and all the DNS servers around the world get it. The record features all the mail servers that are allowed to send legitimate messages from an email address within the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the given domain, the message won't be forwarded and it will be removed. If you use this solution, it will prevent third parties from sending spam that seem to have been sent by you.

SPF Protection in Website Hosting

SPF protection can be enabled for every domain hosted in a website hosting account on our cloud platform with no more than a few mouse-clicks. The feature can be found in the Emails section of our outstanding Hepsia Control Panel and what is needed to activate it is to select one of your domains from the drop-down menu and then type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be certified to send emails from your emails. As an additional option you can even restrict the messages to be sent from your domain only if it includes our MX records, i.e. if our servers manage the email addresses for it, not a third-party supplier. This feature will give you the best degree of safety, but it is not applicable in case only your site is on our servers while your email addresses for the domain name are handled in a different place. Regardless, the SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

The Hepsia hosting Control Panel, that comes with all our semi-dedicated servers, will provide you with an incredibly user-friendly interface to enable the SPF protection service for any domain that you host within your new account. A few clicks in the Emails section of Hepsia will be enough for that then you'll only have to enter the hostname and the IP address of the mail server which will be allowed to send out messages from your email addresses. If the e-mail messages are taken care of on our end and not by some other supplier, you are able to increase the protection level even more and activate an option for your outgoing emails to be sent only if your domains feature our MX records. This option provides you with increased control and it will eliminate any possibility of somebody forging your e-mail addresses with the purpose of spamming and / or scamming people. It is not applicable if just your web site is on our state-of-the-art cloud hosting platform, while your email addresses are handled by a different service provider. If you are not sure what features to choose, our tech support crew will assist you 24/7.
