Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called email spoofing where an e-mail message can be sent from one email, but to appear as being sent from a different one, often with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers worldwide get it. The record includes all of the mail servers that are permitted to send authentic messages from an e-mail address part of the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and when its sending server is authorized, the message is sent to the target receiver. If, however, the sending server doesn't exist in the SPF record for the given domain, the email message won't be sent and it will be removed. Whenever you employ this solution, it will prevent third parties from sending spam that look as if they have been sent by you.

SPF Protection in Shared Hosting

You're able to enable the SPF protection option for your domain names with just a few clicks from the Hepsia Control Panel, which comes with all our shared hosting. This carried out through the section with an identical name and you can set up the protection for each and every domain part of our cutting-edge cloud hosting platform. Using a really convenient interface, all you will have to enter is the hostname of the mail server that will be accredited to send 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, when needed. In case your e-mail addresses are managed on our end, you may also use an even more risk-free option by setting a restriction that email messages can be sent only when your domain names feature our MX records. This alternative can't be applied if your website is hosted with us, and your e-mail addresses are with some third-party service provider. In either case, the SPF protection option can definitely increase your online safety and prevent others from forging your email addresses.
