Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an e-mail message is sent from one e-mail, but to seem as being sent from a different, frequently with the purpose to fraud the recipient someway. When SPF protection is activated for a domain, a specific record is made for it in the Domain Name System and all the DNS servers globally get it. The record includes all of the mail servers that are allowed to send valid messages from an address within the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and in case the sending server is permitted, the message is forwarded to the target destination. If, however, the sending server is not present in the SPF record for the given domain, the email message will not be forwarded and it will be discarded. When you employ this solution, it'll prevent third parties from sending spam emails that appear to have been sent from you.

SPF Protection in Cloud Website Hosting

You can activate the SPF protection service for your domain names with a few clicks inside the Hepsia Control Panel, which comes with all of our Linux cloud website hosting. This is performed via the section with an identical name and you can set up the protection for each and every domain on our state-of-the-art cloud hosting platform. Using a very handy interface, all you will need to enter is the hostname of the mail server that will be accredited to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you are able to include several servers as well, if needed. In case your e-mail addresses are taken care of on our end, you may also employ an even more risk-free option by putting a restriction that messages can be sent only if your domain names feature our MX records. This alternative cannot be used if your website is hosted with us, and the emails are with some third-party provider. In either case, the SPF protection option will significantly increase your online security and prevent other people from forging your email addresses.
