Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to seem as being sent from another, ordinarily with the objective to scam the recipient in some way. When SPF protection is activated for a domain, a special record is created for it in the Domain Name System and all of the DNS servers worldwide have it. The record contains all mail servers that are permitted to send valid messages from an e-mail address within the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and when its sending server is authorized, the message is forwarded to the target receiver. In case, however, the sending server is not present in the SPF record for the particular domain, the message won't be submitted and it'll be removed. In case you use this service, it'll prevent third parties from sending spam messages that appear to have been sent from you.

SPF Protection in Web Hosting

You can activate the SPF protection service for your domains with a few clicks in the Hepsia Control Panel, which is included with our web hosting. This is performed via the section bearing the same name and you are able to allow the protection for each domain on our leading-edge cloud platform. Using a very handy interface, all you will need to enter is the hostname of the mail server that will be accredited to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers too, when needed. In case your emails are handled by us, you can also take advantage of an even more secure option by setting a restriction that emails can be sent only if your domain names feature our MX records. This alternative cannot be applied if your web site is hosted with us, and the email addresses are with some third-party provider. Either way, the SPF protection option can significantly increase your web security and stop other people from forging your email addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from us, you'll be able to protect your email addresses by activating the SPF protection service for every domain name hosted in your account with just a couple of mouse-clicks. You can do this through the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous practical experience with these things, you will not have any kind of trouble to activate the security. The only things that you will need to do is 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 emails will be mailed around the world only if they are sent from that specific server. When your e-mail addresses are managed by us and not by some third-party provider, you'll also be able to benefit from an option for emails to be mailed only when the domain name features our MX records and the aforementioned would be the most secure option. If you have any questions regarding thisfeature, you will be able to get in touch with our support team 24/7.
