Sender Policy Framework, or SPF, is a verification system, which is intended to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to appear as being sent from another one, often with the purpose to fraud the recipient someway. When SPF protection is activated for a domain name, an exclusive record is made for it in the Domain Name System and all of the DNS servers worldwide receive it. The record includes all e-mail servers that are permitted to send authentic messages from an email address part of the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not contained in the SPF record for the particular domain, the email message won't be sent and it'll be removed. If you use this solution, it'll stop third parties from sending spam emails that seem to have been sent by you.

SPF Protection in Web Hosting

You can activate the SPF protection service for your domains with a few clicks inside the Hepsia Control Panel, which is provided with our web hosting plans. This is performed through the section bearing an identical name and you can enable the protection for each domain name on our revolutionary cloud hosting platform. Using a really intuitive interface, all you will need to enter is the hostname of the mail server that will be authorized to send messages from your e-mails and its IPv4 or IPv6 address. Of course, it is possible to add several servers too, when needed. In case your email addresses are handled by us, you may also take advantage of a more secure option by placing a limit that emails can be sent only if your domain names have our MX records. This alternative cannot be used in case your website is hosted here, but the emails are with some third-party provider. In either case, the SPF protection option will really enhance your online security and stop other people from counterfeiting your e-mail addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you can protect your email addresses by enabling the SPF protection service for every domain in your account with just a couple of mouse-clicks. This is done in the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous experience with such things, you won't have any kind of troubles to enable the protection. The only things that you'll need to do will be to pick a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your email addresses will be sent around the world only if they were sent from that server. In case your e-mail addresses are managed by us and not by some third-party supplier, you can also activate an option for e-mail messages to be mailed only when the domain features our MX records and the latter would be the most secure option.
