Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an e-mail message is sent from one email, but to appear as being sent from another, generally with the purpose to fraud the recipient someway. When SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all the DNS servers around the world have it. The record includes all the mail servers that are allowed to send authentic messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is forwarded to the target receiver. In case, 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. When you employ this solution, it'll prevent third parties from sending spam e-mails which look as if they have been sent from you.

SPF Protection in Cloud Hosting

If you host your domain names in a cloud hosting account on our end and we handle the email addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in a separate section where you will be able to see which domains are currently protected. For the ones that aren't, you can enable the SPF protection solution and set up a number of things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only when your domain names use our MX records. The last choice is the most secure one, and it can be used if we manage the email addresses for your domain names and do not use another email supplier. The newly created records will be activated within 1 day and nobody will be able to forge the FROM field in an e-mail with your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you host your domain names in a semi-dedicated server account from our company, you can employ the SPF protection feature as a part of the conventional collection of services that you'll get with this type of web hosting. Starting the protection involves only several easy steps within the Hepsia Control Panel, so even when you haven't employed this kind of function before, you will not have any type of problems. Employing a really easy to work with interface, you'll just need to type in the details of the mail server which will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently generated record propagates, nobody will be able to fake any e-mail for that particular domain name and send messages from a server other than the one you've entered. This does not necessarily have to be our mail server, but if we handle your emails, you will be able to enable an extra level of protection by picking an option that e-mails can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our tech support crew will be able to help you 24/7 in case you have any questions related to this service.
