Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an email message can be sent from one email address, but to appear as being sent from another, generally with the objective to scam the recipient for some reason. When SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all of the DNS servers around the world have it. The record contains all mail servers that are allowed to send legitimate messages from an e-mail address within the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and if the sending server is authorized, the message is forwarded to the target receiver. If, however, the sending server is not contained in the SPF record for the particular domain, the email message will not be submitted and it'll be removed. In case you use this service, it will stop third parties from sending spam messages that appear to have been sent from you.

SPF Protection in Cloud Web Hosting

You'll be able to activate the SPF protection service for your domain names with a couple of clicks inside the Hepsia Control Panel, which is included with all our Linux cloud web hosting services. This is done via the section bearing an identical name and you're able to enable the protection for any domain name part of our cutting-edge cloud hosting platform. Using a very convenient interface, all you will need to submit is the hostname of the mail server that will be approved to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you can add several servers too, if needed. When your emails are managed on our end, you may also use an even more risk-free option by putting a restriction that emails can be sent only if your domain names include our MX records. This solution can't be applied when your web site is hosted with us, and your emails are with a third-party service provider. In either case, the SPF protection solution can vastly enhance your web protection and prevent others from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from us, you are able to protect your email addresses by activating the SPF security service for every domain name in the account with only a couple of clicks. This is done through the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous practical experience with such matters, you will not have any difficulties to enable the protection. The only things that you will have to do will be to choose a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your email addresses will be delivered worldwide only if they're sent from that particular server. If your email addresses are managed by our company and not by some third-party supplier, you'll also be able to use an option for emails to be mailed only when the domain includes our MX records and the latter is the most secure option. If you have any questions related to thisfeature, you will be able to contact our technical support team 24/7.
