SPF, which is short for Sender Policy Framework, is an e-mail security system, that is is intended to confirm if an e-mail message is sent by an authorized server. Employing SPF protection for a particular domain name will stop the counterfeiting of email addresses created with the domain. In layman's terms: activating this feature for a domain name makes a special record in the Domain Name System (DNS) which contains the IP addresses of the servers that are allowed to send emails from mail boxes under the domain. The moment this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Whenever an email message is sent, the first DNS server it uses verifies if it originates from an accredited server. In the event it does, it is sent to the destination address, but if it does not come from a server indexed in the SPF record for the domain, it's rejected. Thus nobody will be able to mask an email address and make it appear as if you're distributing spam. This technique is also identified as email spoofing.

SPF Protection in Cloud Hosting

You are able to activate the SPF protection service for your domain names with only a few clicks in the Hepsia Control Panel, which is included with all of our Linux cloud plans. This carried out via the section bearing the very same name and you can enable the protection for each and every domain name hosted on our state-of-the-art cloud hosting platform. Using a really user-friendly interface, all you need to enter is the hostname of the mail server that will be accredited to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you can include several servers as well, if needed. When your e-mails are managed by us, you can also use an even more risk-free option by placing a restriction that messages can be sent only when your domains include our MX records. This alternative cannot be used when your web site is hosted here, while the e-mail addresses are with some third-party provider. Either way, the SPF protection solution can strongly increase your web protection and stop others from counterfeiting your e-mail addresses.

As an extra option, we'll also allow you to control the outgoing e-mail messages and secure your mailboxes even better by permitting messages to be sent only if the domain involved includes our MX records i.e. the email messages for the domain should be taken care of here and not by another provider.
