Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called email spoofing where an email message can be sent from one address, but to appear as being sent from another one, frequently with the idea to scam the recipient someway. If SPF protection is enabled for a domain, an exclusive record is generated for it in the Domain Name System and all the DNS servers globally have it. The record contains all of the e-mail servers that are allowed to send legitimate messages from an e-mail address within the domain. When an email is sent, the first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the target destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the email message will not be submitted and it will be discarded. In case you employ this solution, it will stop third parties from sending spam emails that appear to have been sent from you.

SPF Protection in Cloud Hosting

You can activate the SPF protection option for your domains with a few clicks from the Hepsia Control Panel, which comes with all of our Linux cloud hosting. This is done through the section bearing the same name and you are able to enable the protection for each domain name hosted on our innovative cloud hosting platform. Using a very simple interface, all you'll have to enter is the hostname of the mail server which will be permitted to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you'll be able to add several servers too, if needed. When your emails are taken care of on our end, you may also use a more risk-free option by placing a limit that e-mail messages can be sent only when your domains include our MX records. This alternative cannot be applied if your site is hosted here, while the e-mail addresses are with a third-party provider. Either way, the SPF protection option will significantly enhance your web protection and prevent other people from spoofing your e-mail addresses.
