Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from a different, typically with the idea to scam 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 DNS servers worldwide have it. The record contains all of the email servers that are allowed to send legitimate messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is permitted, the message is forwarded to the target destination. If, however, the sending server is not present in the SPF record for the specified domain, the email message won't be sent and it will be removed. In the event that you employ this service, it will stop third parties from sending spam e-mails that seem to have been sent by you.

SPF Protection in Cloud Website Hosting

If you host your domains in a cloud website hosting account on our end and we manage the emails for them, you'll be able to enable SPF protection for all of them with several clicks inside your Hepsia Control Panel. This service can be found in a section of its own where you are able to see which domains are already secured. For the ones that are not, you will be able to activate the SPF protection solution and manage a variety of things during the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only if your domain names use our MX records. The last choice is the most secure one, but it can be used in the event that we take care of the emails for your domains and you are not using a different email supplier. The newly generated records will be activated within 1 day and nobody will be able to forge the FROM field in a message with your e-mail addresses.

SPF Protection in Semi-dedicated Servers

When you host your domain names in a semi-dedicated server account with us, you can use the SPF protection feature as part of the conventional group of services that you'll get using this type of hosting. Enabling the protection involves just several easy steps in the Hepsia Control Panel, so even when you have never employed this kind of function before, you will not have any kind of troubles. Employing a very easy-to-navigate interface, you'll only have to insert the information of the mail server that will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly made record propagates, no one will be able to fake any e-mail for that particular domain name and send out emails from a server different from the one you've typed in. This does not specifically have to be our mail server, still if we handle your e-mails, you will be able to allow an extra level of security by choosing an option that e-mails can be send out from addresses @your-domain.com only if the domain employs our MX records. Our tech support crew can help you 24/7 if you have any questions related to this service.
