SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is used to validate whether an e-mail message is sent by an official server. Employing SPF protection for a domain will prevent the counterfeiting of email addresses generated with the domain. In simple words: enabling this attribute for a domain name creates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mail messages from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. Every time an email message is sent, the first DNS server it goes through verifies if it originates from an approved server. In the event it does, it is forwarded to the destination address, however when it doesn't originate from a server listed in the SPF record for the particular domain, it is discarded. In this way nobody will be able to mask an email address then make it appear as if you're e-mailing spam messages. This technique is also termed email spoofing.

SPF Protection in Cloud Web Hosting

You are able to activate the SPF protection option for your domain names with just a couple of clicks inside the Hepsia Control Panel, which is provided with our cloud web hosting service. This is done from the section bearing the same name and you are able to set up the protection for each and every domain name hosted on our state-of-the-art cloud hosting platform. Using a very convenient interface, all you will have to type in is the hostname of the mail server which will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you are able to add several servers too, if needed. When your email addresses are handled on our end, you can also employ a more risk-free option by setting a limit that email messages can be sent only if your domains feature our MX records. This alternative can't be used if your website is here, and your emails are with some third-party provider. Either way, the SPF protection solution can greatly increase your web protection and prevent other people from spoofing your e-mail addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you'll be able to protect your email addresses by activating the SPF protection service for every domain hosted in the account with just a few mouse-clicks. This is done through the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of issues, you won't have any kind of troubles to enable the security. Everything that you will have to do is to select a domain name from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your emails will be mailed globally only if they're sent from that server. In case your emails are managed by our company and not by a third-party provider, you can also activate an option for e-mail messages to be sent only if the domain name features our MX records and the latter would be the most secure option.
