Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called e-mail spoofing where an e-mail message is sent from one email address, but to seem as being sent from another, usually with the objective to fraud the recipient someway. When SPF protection is enabled for a domain name, a unique record is generated for it in the Domain Name System and all DNS servers around the world receive it. The record contains all email servers that are permitted to send authentic messages from an address under the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the email message won't be submitted and it will be discarded. When you use this service, it'll stop third parties from sending spam e-mails which seem to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be activated for each domain hosted in a cloud hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The option is accessible in the Emails section of our modern Hepsia Control Panel and what is needed to use it is to choose one of your domains from a drop-down list and to enter the hostnames along with the IPv4 or IPv6 addresses of the email servers which will be certified to send messages from your email addresses. As an added option you can also restrict the emails to be sent from your domain name only when it has our MX records, in other words if our servers handle the e-mail addresses for it, not some third-party provider. This option will provide you with the best standard of security, but it's not applicable when only your site is on our servers while the emails for the domain name are taken care of somewhere else. Regardless, our SPF protection service will keep your email addresses secure from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account with us, you are able to secure your email addresses by activating the SPF security service for any domain hosted in your account with only a couple of mouse-clicks. This is done from the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even if you have no previous experience with these kinds of matters, you won't have any kind of difficulties to activate the security. All that you will need to do will be to choose a domain from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your email addresses will be delivered worldwide only if they're sent from that server. If your email addresses are handled by our company and not by some third-party provider, you can also use an option for emails to be sent only if the domain contains our MX records and this is the most secure option.
