Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called email spoofing where an e-mail message can be sent from one email address, but to seem as being sent from another one, generally with the objective to fraud the recipient someway. When SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all of the DNS servers around the world have it. The record includes all of the e-mail servers that are allowed to send valid messages from an address within the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and in case the sending server is permitted, 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 message will not be submitted and it will be removed. If you use this solution, it'll prevent third parties from sending spam e-mails that seem to have been sent from you.

SPF Protection in Cloud Hosting

You'll be able to enable the SPF protection service for your domain names with a few clicks from the Hepsia Control Panel, which is included with all of our Linux cloud hosting plans. This carried out through the section bearing the very same name and you can set up the protection for any domain part of our modern cloud platform. Using a really simple interface, all you'll need to submit is the hostname of the mail server which will be approved to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you're able to add several servers as well, when needed. When your e-mails are handled on our end, you may also take advantage of an even more risk-free option by setting a restriction that e-mail messages can be sent only if your domain names have our MX records. This option cannot be applied when your website is hosted here, while your emails are with a third-party service provider. Either way, the SPF protection solution can considerably enhance your web security and stop others from forging your email addresses.

The SPF protection function is provided with all semi-dedicated servers, so if you host your domains in an account on our cloud website hosting platform, you are able to use the service with ease for all your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, offers a quite easy to work with interface, therefore you won't have to be tech-savvy to secure your e-mails. You will only need to type the hostname and the IP of each mail server that you'd like to be authorized to send e-mails from your addresses and immediately after that the updated record will be activated for the domain that you have picked. As a further option, we will also give you the ability to limit the outgoing emails and protect your mailboxes even better by permitting emails to be sent only when the domain name in question contains our MX records i.e. the emails for the domain name need to be handled here and not by some other company.
