Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called email spoofing where an email message is sent from one email, but to appear as being sent from a different, frequently with the purpose to scam the recipient in some way. If SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all DNS servers globally have it. The record features all of the e-mail servers that are permitted to send legitimate messages from an e-mail address under the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and when the sending server is permitted, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the given domain, the email message won't be submitted and it will be discarded. If you use this service, it'll prevent third parties from sending spam emails which look as if they have been sent by you.

SPF Protection in Cloud Hosting

SPF protection can be activated for any domain hosted in a cloud hosting account on our cloud platform with just a few clicks. The option can be found in the Emails section of our leading-edge Hepsia Control Panel and all you need to activate it is to select one of your domains from a drop-down menu and type in the hostnames along with the IPv4 or IPv6 addresses of the email servers which will be permitted to send messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain name only when it includes our MX records, i.e. when our servers handle the emails for it, not some third-party supplier. This solution gives you the highest standard of protection, but it's not applicable in case only your web site is on our servers while your e-mail addresses for the domain name are taken care of somewhere else. In either case, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
