SPF, which stands for Sender Policy Framework, is an e-mail security system, which is employed to confirm if an e-mail message was sent by a certified server. Employing SPF protection for a given domain will stop the counterfeiting of email addresses made with the domain. In layman's terms: activating this attribute for a domain name makes a specific record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send e-mails from mailboxes using the domain. Once this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. Whenever an email message is sent, the first DNS server it goes through verifies if it comes from an approved server. When it does, it is sent to the destination address, yet if it doesn't originate from a server indexed in the SPF record for the domain, it is discarded. Thus nobody will be able to mask an e-mail address then make it look as if you are distributing spam messages. This method is also termed email spoofing.
SPF Protection in Shared Web Hosting
SPF protection can be activated for every domain hosted in a shared web hosting account on our cloud hosting platform with only a couple of clicks. The function can be found in the Emails section of our state-of-the-art Hepsia Control Panel and all it takes to enable it is to pick one of your domains from the drop-down list and to type in the hostnames plus the IPv4 or IPv6 addresses of the mail servers that will be approved to send messages from your emails. As an additional option you can also restrict the messages to be sent from your domain name only if it has our MX records, in other words when our servers manage the e-mail addresses for it, not a third-party supplier. This option offers you the best standard of safety, but it is not applicable if only your site is on our servers while the e-mail addresses for the domain are handled somewhere else. In either case, our SPF protection service will keep your emails protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection function is provided with all of the Linux semi-dedicated hosting, so when you host your domain names in an account on our cloud website hosting platform, you'll be able to activate this service easily for all of your domains. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a very easy to use interface, therefore you won't need to be tech-savvy in order to secure your e-mails. You will only have to type the hostname and the IP address of each mail server that you'd like to be certified to send out e-mails from your addresses and immediately after that the new record will be active for the domain that you have chosen. As a further option, we'll also give you the ability to control the outgoing emails and protect your mailboxes even further by permitting emails to be sent only if the domain name in question has our MX records i.e. the email messages for the domain name should be managed here and not by a different supplier. By doing so you will have even better control and there will not be a chance for someone to forge your email addresses for harmful activities.
