Sender Policy Framework, or SPF, is a validation system, that is used to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different, typically with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all the DNS servers globally receive it. The record features all the email servers that are permitted to send valid messages from an email address part of the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is sent to the target receiver. In case, however, the sending server is not included in the SPF record for the given domain, the message will not be sent and it will be removed. If you employ this service, it will prevent third parties from sending spam which appear to have been sent from you.

SPF Protection in Shared Web Hosting

When you host your domain names in a shared web hosting account with us and we manage the e-mails for them, you will be able to enable SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service is available in a separate section where you can view which domain names are already protected. For the ones that are not, you'll be able to activate the SPF protection solution and set up various things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and to set a rule that emails can be sent only when your domain names include our MX records. The aforementioned solution is the most secure one, but you can use it when we handle the emails for your domain names and do not use some other e-mail supplier. The newly generated records will be activated within 1 day and nobody will be able to forge the FROM field in a message 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 our company, you can take advantage of the SPF protection feature as part of the conventional set of services that you will receive with this type of hosting. Activating the protection will involve only a few simple steps in the Hepsia Control Panel, thus even if you haven't used this type of feature before, you won't have any kind of issues. Through a really easy to work with interface, you'll just have to enter the info of the mail server which will be certified to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly made record propagates, no one will be able to forge any e-mail address for that particular domain and send out messages from a server different from the one you've typed in. This doesn't specifically have to be our mail server, yet in case we manage your email messages, you're able to enable an extra level of security by choosing an option that email messages can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our tech support team can assist you 24/7 if you have any kind of questions regarding this service.
