SPF, which means Sender Policy Framework, is an email security system, which is is intended to validate if an e-mail message is sent by an official server. Using SPF protection for a domain name will prevent the forging of email addresses generated with the domain. In layman's terms: activating this function for a domain name makes a particular record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send e-mail messages from mail boxes using the domain. As soon as this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it uses verifies whether it comes from an authorized server. In the event it does, it's sent to the destination address, but if it doesn't originate from a server indexed in the SPF record for the particular domain, it is discarded. Thus nobody will mask an email address to make it look as if you are distributing spam messages. This method is also termed email spoofing.
SPF Protection in Cloud Hosting
If you host your domains in a cloud hosting account on our end and we handle the email addresses for them, you'll be able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a separate section where you'll be able to view which domains are already protected. For the ones which aren't, you'll be able to enable the SPF protection option and set up various things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and to create a rule that emails can be sent only if your domains use our MX records. The aforementioned option is the most secure one, and it can be used when we manage the e-mail addresses for your domain names and you are not using another email service provider. The newly created records will propagate within a day and nobody will be able to forge the FROM field in a message by using your email addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account from our company, you are able to take advantage of the SPF protection feature as part of the conventional collection of services that you'll get with this type of web hosting. Enabling the protection involves only a few simple steps within the Hepsia Control Panel, thus even in case you haven't used such a function before, you will not have any issues. Using an exceptionally intuitive interface, you'll just have to input the information of the mail server which will be certified to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently created record propagates, nobody will be able to counterfeit any e-mail address for that particular domain name and send email messages from a server different from the one you have entered. This doesn't necessarily have to be our mail server, still in case we manage your e-mails, you'll be able to activate an extra level of protection by picking an option that emails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our tech support crew will be able to assist you 24/7 if you have any questions related to this service.
