Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called email spoofing where an email message is sent from one e-mail address, but to appear as being sent from another, typically with the idea to fraud 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 the DNS servers around the world have it. The record includes all of the e-mail servers that are permitted to send authentic messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is forwarded to the targeted receiver. If, however, the sending server is not included in the SPF record for the particular domain, the message won't be sent and it will be discarded. If you use this service, it will stop third parties from sending spam emails which seem to have been sent from you.

SPF Protection in Web Hosting

This carried out from the section with the very same name and you'll be able to allow the protection for each and every domain hosted on our leading-edge cloud platform. Using a very time and effort saving interface, all you will need to enter is the hostname of the mail server which will be accredited to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to include several servers too, if needed. In case your emails are managed by us, you may also take advantage of a more risk-free option by setting a limit that emails can be sent only if your domain names have our MX records. This option can't be applied if your web site is hosted with us, and the email addresses are with some third-party provider. In either case, the SPF protection option can greatly enhance your online protection and stop other people from spoofing your e-mail addresses.
