SPF, which means Sender Policy Framework, is an email safety system, that is designed to verify if an email message was sent by an authorized server. Using SPF protection for a given domain name will stop the counterfeiting of emails generated with the domain. In layman's terms: activating this attribute for a domain name creates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send e-mail messages from mailboxes using the domain. The moment this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. Any time some e-mail message is sent, the first DNS server it goes through tests whether it originates from an approved server. If it does, it is sent to the destination address, but if it does not come from a server listed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an e-mail address then make it look as if you're e-mailing spam messages. This technique is also known as email spoofing.
SPF Protection in Cloud Hosting
If you host your domains in a cloud hosting account on our end and we handle the e-mails for them, you'll be able to activate SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service can be found in its own section where you will be able to see which domain names are already secured. For those that are not, you'll be able to enable the SPF protection service and set up a number of things during this process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and to create a rule that email messages can be sent only if your domain names include our MX records. The last mentioned choice is the most secure one, but you can use it when we take care of the e-mails for your domain names and you're not using another e-mail service provider. The new records will be activated within one day and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account with our company, you will be able to benefit from the SPF protection feature as part of the regular set of services that you'll get using this type of hosting. Enabling the protection will involve only several simple steps within the Hepsia Control Panel, so even when you haven't employed such a function before, you will not have any kind of issues. Employing a very intuitive interface, you will only have to type in the information of the mail server that will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly generated record propagates, no one will be able to forge any e-mail address for that particular domain name and send email messages from a server other than the one you've entered. This doesn't necessarily have to be our mail server, still in case we take care of your emails, you'll be able to activate an additional level of protection by choosing an option that e-mail messages can be send out from addresses @your-domain.com only if the domain uses our MX records. Our tech support crew will be able to assist you 24/7 if you have any kind of questions regarding this service.
