Sender Policy Framework, or SPF, is a validation system, that is used to stop the so-called email spoofing where an e-mail message is sent from one email address, but to look as being sent from another one, frequently with the purpose to scam the recipient someway. If SPF protection is enabled for a domain name, a special record is made for it in the Domain Name System and all of the DNS servers worldwide receive it. The record features all of the e-mail servers that are allowed to send authentic messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and if its sending server is authorized, the message is forwarded to the target receiver. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be forwarded and it will be discarded. When you employ this service, it'll prevent third parties from sending spam messages that seem to have been sent from you.
SPF Protection in Shared Website Hosting
SPF protection can be activated for each domain hosted in a shared website hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The function is available in the Emails section of our leading-edge Hepsia Control Panel and all you need to activate it is to pick one of your domains from a drop-down list and then type in the hostnames and the IPv4 or IPv6 addresses of the mail servers which will be permitted to send emails from your email addresses. As an added option you can also restrict the messages to be sent from your domain name only when it has our MX records, in other words if our servers manage the emails for it, not some third-party provider. This feature gives you the best degree of security, but it is not applicable if only your site is on our servers while your email addresses for the domain are managed somewhere else. Either way, our SPF protection service will keep your emails secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
If you host your domains in a semi-dedicated server account with our company, you can use the SPF protection feature as a part of the regular collection of services that you'll receive with this kind of web hosting. Enabling the protection involves only a few easy steps in the Hepsia Control Panel, thus even if you've never employed this kind of feature before, you won't have any type of issues. Employing an exceptionally time and effort saving interface, you'll only need to input the info of the mail server which will be authorized to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly made record propagates, no one will be able to fake any email address for that particular domain and send out email messages from a server different from the one you've entered. This does not specifically have to be our mail server, yet when we take care of your email messages, you're able to allow an extra level of security by choosing an option that e-mail messages can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our tech support team can help you 24/7 in case you have any questions about this service.
