SPF, which is an acronym for Sender Policy Framework, is an email security system, which is used to validate whether an email message was sent by an authorized server. Employing SPF protection for a particular domain will stop the faking of email addresses created with the domain. In simple words: enabling this attribute for a domain makes a specific record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send e-mails from mail boxes using the domain. Once this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. When an email message is sent, the first DNS server it uses verifies whether it originates from an authorized server. In the event it does, it is sent to the destination address, but when it does not originate from a server listed in the SPF record for the domain, it is rejected. In this way nobody will be able to mask an email address and make it look as if you are e-mailing spam messages. This method is also known as email spoofing.
SPF Protection in Cloud Hosting
If you host your domain names in a cloud hosting account on our end and we manage the email addresses for them, you'll be able to enable SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in its own section where you're able to view which domains are already protected. For the ones which aren't, you can activate the SPF protection solution and configure numerous 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 messages can be sent only if your domains include our MX records. The last mentioned solution is the most secure one, but you can use it when we handle the emails for your domains and do not use another email supplier. The newly created records will be activated within 24 hours and nobody will be able to forge the FROM field in an e-mail by using your addresses.
SPF Protection in Semi-dedicated Servers
When you host your domain names in a semi-dedicated server account from us, you can employ the SPF protection feature as a part of the conventional collection of services that you will receive with this type of web hosting. Starting the protection will require just a couple of easy steps within the Hepsia Control Panel, therefore even when you haven't employed this type of function before, you will not have any kind of issues. Through a very easy-to-use interface, you'll simply have to type in the info of the mail server that will be authorized to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly generated record propagates, nobody will be able to fake any email address for that particular domain and send out e-mail messages from a server other than the one you have typed in. This does not specifically have to be our mail server, still if we handle your email messages, you will be able to allow an additional level of protection by choosing an option that emails can be send from addresses @your-domain.com only in case the domain uses our MX records. Our technical support staff can assist you 24/7 if you have any questions related to this service.
