SPF, which is an acronym for Sender Policy Framework, is an email safety system, that is employed to validate if an email message was sent by an authorized server. Employing SPF protection for a particular domain will stop the counterfeiting of email addresses created with the domain. In layman's terms: activating this function for a domain name makes a specific record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send emails from mail boxes under the domain. As soon as this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. When some email message is sent, the initial DNS server it goes through verifies whether it comes from an accredited server. When it does, it is forwarded to the destination address, but when it doesn't come from a server part of the SPF record for the domain, it's discarded. In this way nobody can mask an e-mail address then make it appear as if you're distributing spam messages. This technique is also known as email spoofing.
SPF Protection in Web Hosting
SPF protection can be enabled for each domain hosted in a web hosting account on our cloud platform with only a couple of clicks. The function is accessible in the Emails section of our advanced Hepsia Control Panel and all you need to enable it is to choose one of your domains from the drop-down menu and to enter the hostnames plus the IPv4 or IPv6 addresses of the mail servers that will be permitted to send emails from your emails. As an additional option you can even restrict the email messages to be sent from your domain name only if it has our MX records, in other words if our servers handle the emails for it, not a third-party provider. This option will give you the highest level of safety, but it is not applicable when only your site is on our servers while the email addresses for the domain are handled in another place. Regardless, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you will be able to protect your email addresses by enabling the SPF protection service for any domain name hosted in the account with just a few clicks. This can be done through the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of things, you won't have any kind of troubles to enable the security. All that you'll need to do is to pick a domain name from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your emails will be mailed worldwide only if they're sent from that particular server. When your e-mail addresses are taken care of by us and not by a third-party provider, you can also activate an option for email messages to be mailed only if the domain name features our MX records and the latter would be the safest option. Should you have any kind of questions regarding thisfeature, you will be able to get in touch with our technical support crew 24/7.
