Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different one, generally with the objective to scam the recipient for some reason. If SPF protection is activated for a domain, a unique record is generated for it in the Domain Name System and all the DNS servers worldwide receive it. The record includes all the email servers that are allowed to send valid messages from an e-mail address within the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server doesn't exist in the SPF record for the given domain, the message will not be sent and it'll be discarded. If you use this solution, it'll prevent third parties from sending spam e-mails that seem to have been sent by you.
SPF Protection in Shared Web Hosting
You are able to activate the SPF protection option for your domains with a few clicks from the Hepsia Control Panel, which comes with all of our Linux shared web hosting services. This is performed from the section bearing the same name and you're able to enable the protection for each domain name part of our exceptional cloud platform. Using a really simple interface, all you'll need to submit is the hostname of the mail server which will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers too, when needed. When your email addresses are managed by us, you may also employ an even more secure option by placing a restriction that emails can be sent only when your domains feature our MX records. This solution cannot be applied when your website is hosted with us, and the e-mail addresses are with a third-party provider. Either way, the SPF protection solution can tremendously improve your online security and stop other people from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account with our company, you are able to employ the SPF protection feature as part of the conventional group of services that you will have using this type of web hosting. Starting the protection will require only a couple of simple steps in the Hepsia Control Panel, thus even if you haven't employed this type of function before, you will not have any issues. Through an exceptionally time and effort saving interface, you will only have to type in the information of the mail server which will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently made record propagates, nobody will be able to counterfeit any email for that particular domain and send emails from a server different from the one you've typed in. This does not necessarily have to be our mail server, however if we manage your email messages, you're able to activate one more level of security by choosing an option that e-mails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our technical support staff can help you 24/7 if you have any questions related to this service.
