Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called email spoofing where an email message can be sent from one email address, but to seem as being sent from another, typically with the purpose to fraud the recipient someway. When SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all DNS servers around the world get it. The record features all the mail servers that are permitted to send valid messages from an e-mail address within the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server is not included in the SPF record for the given domain, the message will not be sent and it will be removed. In the event that you use this solution, it'll prevent third parties from sending spam emails which look as if they have been sent from you.

SPF Protection in Website Hosting

SPF protection can be enabled for every domain name hosted in a website hosting account on our cloud hosting platform with no more than a few mouse-clicks. The option is accessible in the Emails section of our modern Hepsia Control Panel and what is needed to use it is to choose one of your domains from a drop-down menu and to type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers which will be authorized to send emails from your emails. As an additional option you may also restrict the email messages to be sent from your domain name only when it has our MX records, i.e. if our servers manage the e-mail addresses for it, not a third-party provider. This solution will provide you with the best standard of safety, but it's not applicable if only your site is on our servers while the email addresses for the domain name are managed elsewhere. Regardless, the SPF protection service will keep your emails secure from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Hosting

The Hepsia website hosting Control Panel, which comes as standard with all of our semi-dedicated services, provides you with an exceptionally user-friendly interface to enable the SPF protection service for every domain name that you host in your new account. A few clicks in the Emails section of Hepsia will be enough for that and you will only have to enter the hostname and the IP address of the mail server that will be allowed to send messages from your email addresses. If the e-mails are taken care of on our end and not by a different supplier, you are able to raise the security level even further and activate an option for the outgoing email messages to be sent only if your domains feature our MX records. This option will give you more control and it'll eliminate any chance of anybody faking your e-mails with the objective of spamming and / or scamming people. It's not applicable if just your website is on our outstanding cloud hosting platform, while your emails are handled by some other provider. If you are not sure what options to select, our technical support crew will assist you 24/7.
