SPF, which is an acronym for Sender Policy Framework, is an email safety system, which is used to confirm whether an email message is sent by an authorized server. Using SPF protection for a particular domain will prevent the faking of emails generated with the domain. In layman's terms: activating this function for a domain creates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send email messages from mailboxes under the domain. The moment this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time a new email message is sent, the initial DNS server it uses checks if it comes from an authorized server. In the event it does, it is forwarded to the destination address, yet if it does not originate from a server indexed in the SPF record for the domain, it's rejected. Thus nobody can mask an e-mail address to make it look as if you're sending spam. This approach is also referred to as email spoofing.
SPF Protection in Hosting
You can activate the SPF protection service for your domains with only a couple of clicks from the Hepsia Control Panel, which is included in our Linux hosting. This is performed from the section with an identical name and you're able to allow the protection for each domain part of our outstanding cloud hosting platform. Using a very handy interface, all you need to enter is the hostname of the mail server which will be authorized to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to include several servers as well, if needed. When your emails are handled by us, you can also employ an even more secure option by placing a restriction that emails can be sent only if your domains feature our MX records. This solution cannot be applied when your website is hosted with us, while the e-mail addresses are with some third-party service provider. In either case, the SPF protection solution can considerably increase your online security and prevent other people from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature comes with all the Linux semi-dedicated hosting, so in case you host your domains in an account on our cloud website hosting platform, you're able to activate the service with ease for all of your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, offers a very easy to work with interface, therefore you won't need to be tech-savvy in order to protected your e-mails.

As an additional option, we will also allow you to limit the outgoing email messages and protect your mailboxes further by allowing emails to be sent only when the domain in question contains our MX records i.e. the e-mail messages for the domain have to be taken care of by us and not by some other company. By doing so you'll get even better control and there will not be any chances for any person to counterfeit your email addresses for malicious intentions.
