SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is used to confirm whether an email message was sent by an authorized server. Employing SPF protection for a given domain name will stop the forging of email addresses generated with the domain. In layman's terms: enabling this feature for a domain creates a specific record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send email messages from mailboxes under the domain. The moment this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. Every time a new e-mail message is sent, the initial DNS server it uses checks if it originates from an official server. If it does, it is forwarded to the destination address, however if it doesn't originate from a server listed in the SPF record for the domain, it's rejected. Thus nobody can mask an email address and make it look as if you're sending spam. This technique is also known as email spoofing.

SPF Protection in Cloud Hosting

You are able to activate the SPF protection option for your domain names with only a few clicks in the Hepsia Control Panel, which is included with all our cloud hosting plans. This is performed via the section with the same name and you are able to allow the protection for each domain name on our leading-edge cloud platform. Using a really handy interface, all you need to type in is the hostname of the mail server that will be approved to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you'll be able to add several servers too, when needed. If your e-mail addresses are managed on our end, you may also employ a more risk-free option by setting a restriction that messages can be sent only if your domains feature our MX records. This option cannot be used when your site is hosted with us, and the e-mails are with a third-party service provider. Either way, the SPF protection option will strongly increase your web protection and prevent other people from spoofing your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from our company, you will be able to secure your emails by enabling the SPF security service for every domain name in the account with only a couple of clicks. This is done in the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even when you have no previous practical experience with these kinds of things, you won't have any kind of troubles to activate the security. The only things that you will have to do will be to select a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your email addresses will be mailed worldwide only if they're sent from that specific server. In case your e-mail addresses are managed by us and not by a third-party supplier, you will also be able to activate an option for e-mail messages to be mailed only when the domain has our MX records and the latter is the most secure option. Should you have any kind of questions regarding thisfunction, you will be able to contact our technical support crew 24/7.
