Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to appear as being sent from another one, often with the idea to scam the recipient someway. If SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all DNS servers around the world receive it. The record includes all of the email servers that are allowed to send valid messages from an email address under the domain. When an e-mail 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. When, however, the sending server is not included in the SPF record for the specified domain, the e-mail message won't be forwarded and it'll be removed. In the event that you use this service, it'll prevent third parties from sending spam messages that look as if they have been sent from you.
SPF Protection in Shared Hosting
When you host your domains in a shared hosting account with us and we manage the email addresses for them, you will be able to enable SPF protection for any of them with a few clicks inside your Hepsia Control Panel. The service is accessible in its own section where you are able to see which domains are already protected. For the ones which aren't, you can activate the SPF protection solution and configure a lot of things in the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only if your domain names use our MX records. The last mentioned choice is the most secure one, but it can be used when we handle the emails for your domain names and you're not using another e-mail supplier. The new records will be activated within a day and nobody will be able to forge the FROM field in an e-mail by using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you host your domain names in a semi-dedicated server account from us, you are able to take advantage of the SPF protection feature as part of the conventional group of services that you will have using this kind of hosting. Activating the protection involves just a few simple steps in the Hepsia Control Panel, therefore even when you've never used this kind of function before, you will not have any type of issues. Through an exceptionally user-friendly interface, you will simply have to type in the details of the mail server which will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly generated record propagates, nobody will be able to counterfeit any email address for that particular domain name and send emails from a server different from the one you've typed in. This does not specifically have to be our mail server, however in case we take care of your emails, you will be able to activate an extra level of security by picking an option that email messages can be send from addresses @your-domain.com only in the event that the domain uses our MX records. Our technical support staff can assist you 24/7 if you have any questions regarding this service.
