Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called email spoofing where an email message is sent from one email, but to appear as being sent from a different one, often with the objective to fraud the recipient in some way. If SPF protection is enabled for a domain, an exclusive record is generated for it in the Domain Name System and all the DNS servers worldwide get it. The record features all the e-mail servers that are permitted to send legitimate messages from an address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and if its sending server is permitted, the message is forwarded to the target destination. In case, however, the sending server is not contained in the SPF record for the given domain, the e-mail message will not be forwarded and it will be removed. Whenever you use this service, it'll prevent third parties from sending spam emails that appear to have been sent by you.

SPF Protection in Shared Web Hosting

SPF protection can be enabled for each domain hosted in a shared web hosting account on our cloud hosting platform with only a couple of mouse-clicks. The function is available in the Emails section of our revolutionary Hepsia Control Panel and all it takes to use it is to select one of your domain names from the drop-down list and then type in the hostnames along with the IPv4 or IPv6 addresses of the e-mail servers which will be authorized to send emails from your emails. As an added option you can even restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. when our servers handle the e-mail addresses for it, not some third-party provider. This feature provides you with the top degree of safety, but it's not applicable when only your site is on our servers while the emails for the domain are managed in a different place. In either case, our SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.
