Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an e-mail message is sent from one email address, but to seem as being sent from another one, ordinarily with the purpose to scam the recipient for some reason. If SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all of the DNS servers around the world have it. The record includes all the e-mail servers that are permitted to send valid messages from an address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and if the sending server is authorized, the message is forwarded to the target destination. In case, however, the sending server is not present in the SPF record for the specified domain, the email message will not be sent and it will be discarded. Whenever you employ this solution, it'll stop third parties from sending spam e-mails that seem to have been sent from you.
SPF Protection in Shared Website Hosting
You can enable the SPF protection option for your domains with just a couple of clicks in the Hepsia Control Panel, which is included in our shared website hosting. This is performed through the section bearing the very same name and you'll be able to set up the protection for each domain part of our outstanding cloud platform. Using a very simple interface, all you have to submit is the hostname of the mail server which will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, it is possible to include several servers as well, when needed. When your email addresses are handled on our end, you can also use a more risk-free option by setting a limit that e-mail messages can be sent only when your domain names include our MX records. This alternative can't be applied if your website is here, and your email addresses are with some third-party provider. In either case, the SPF protection option will greatly improve your online security and prevent others from spoofing your email addresses.
