SPF, which means Sender Policy Framework, is an email protection system, which is used to confirm if an email message is sent by a licensed server. Using SPF protection for a given domain name will stop the faking of emails made with the domain. In layman's terms: enabling this attribute for a domain name generates a specific record in the Domain Name System (DNS) containing the IP addresses of the servers which are permitted to send e-mail messages from mail boxes using the domain. When this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. When an e-mail message is sent, the initial DNS server it uses tests if it originates from an accredited server. When it does, it's forwarded to the destination address, yet when it doesn't come from a server part of the SPF record for the particular domain, it's discarded. In this way nobody can mask an email address then make it appear as if you're e-mailing spam. This technique is also termed email spoofing.
SPF Protection in Shared Hosting
SPF protection can be enabled for each domain hosted in a shared hosting account on our cloud hosting platform with only a couple of mouse-clicks. The option is accessible in the Emails section of our innovative Hepsia Control Panel and all it takes to use it is to choose one of your domain names from the drop-down list and then type in the hostnames and the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send messages from your email addresses. As an added option you may also restrict the e-mails to be sent from your domain name only when it has our MX records, i.e. if our servers handle the e-mail addresses for it, not some third-party supplier. This solution provides you with the highest standard of safety, but it is not applicable if only your web site is on our servers while your emails for the domain are taken care of somewhere else. Regardless, the SPF protection service will keep your email addresses risk-free from being used for spam or scam purposes.
