SPF, which is an acronym for Sender Policy Framework, is an e-mail protection system, which is employed to confirm whether an e-mail message was sent by a licensed server. Employing SPF protection for a domain will stop the counterfeiting of email addresses created with the domain. In simple words: enabling this attribute for a domain name creates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send e-mails from mail boxes using the domain. When this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Every time a new email message is sent, the first DNS server it uses verifies if it originates from an accredited server. When it does, it's sent to the destination address, however when it does not originate from a server listed in the SPF record for the particular domain, it's discarded. Thus nobody can mask an e-mail address then make it appear as if you're distributing spam. This technique is also identified as email spoofing.
SPF Protection in Web Hosting
When you host your domains in a web hosting account on our end and we handle the email addresses for them, you are able to enable SPF protection for them with a few clicks in your Hepsia Control Panel. The service is accessible in its own section where you will be able to view which domains are already protected. For those that aren't, you will be able to activate the SPF protection service and configure various things during this process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that email messages can be sent only when your domain names include our MX records. The last mentioned option is the most secure one, and you can use it in the event that we manage the email addresses for your domains and do not use some other email supplier. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in an e-mail using your email addresses.
SPF Protection in Semi-dedicated Hosting
If you host your domains in a semi-dedicated server account with us, you are able to use the SPF protection feature as part of the regular collection of services that you will have with this kind of website hosting. Activating the protection requires just a few simple steps inside the Hepsia Control Panel, so that even in case you have never employed this type of function before, you won't have any kind of troubles. Through an exceptionally intuitive interface, you'll just have to input the details of the mail server that will be permitted to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently created record propagates, no one will be able to counterfeit any e-mail address for that particular domain name and send out messages from a server different from the one you have typed in. This doesn't necessarily have to be our mail server, yet when we take care of your email messages, you're able to enable an additional level of security by picking an option that e-mail messages can be send out from addresses @your-domain.com only if the domain uses our MX records. Our technical support team will be able to help you 24/7 in case you have any questions about this service.
