SPF, which stands for Sender Policy Framework, is an email security system, that is used to verify if an e-mail message is sent by a licensed server. Employing SPF protection for a particular domain will stop the faking of email addresses created with the domain. In simple words: enabling this feature for a domain name creates a specific record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send e-mail messages from mail boxes using the domain. When this record propagates globally, it exists on all the DNS servers that route the Internet traffic. When some email message is sent, the first DNS server it uses verifies whether it originates from an official server. When it does, it's sent to the destination address, but when it doesn't originate from a server indexed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an email address to make it look as if you're distributing spam. This technique is also referred to as email spoofing.
SPF Protection in Shared Hosting
SPF protection can be enabled for each domain hosted in a shared hosting account on our cloud platform with just a couple of mouse-clicks. The function is available in the Emails section of our state-of-the-art Hepsia Control Panel and all you need to enable it is to pick 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 email servers that will be authorized to send email messages from your emails. As an additional option you can even restrict the emails to be sent from your domain only if it includes our MX records, i.e. if our servers handle the e-mail addresses for it, not some third-party supplier. This solution will provide you with the top degree of security, but it's not applicable in case only your site is on our servers while the e-mail addresses for the domain are managed in another place. In either case, the SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
