Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called e-mail spoofing where an email message can be sent from one email address, but to seem as being sent from a different one, frequently with the purpose to fraud the recipient for some reason. If SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all of the DNS servers worldwide have it. The record includes all mail servers that are permitted to send valid messages from an e-mail address within the domain. When an email is sent, the first DNS server it encounters checks the SPF record and when its sending server is authorized, the message is forwarded to the target receiver. In case, however, the sending server is not contained in the SPF record for the specified domain, the email message won't be submitted and it will be removed. In the event that you employ this service, it will prevent third parties from sending spam e-mails that look as if they have been sent by you.

SPF Protection in Shared Hosting

SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud platform with just a couple of clicks. The function can be found in the Emails section of our modern Hepsia Control Panel and all you need to use it is to pick one of your domain names from the drop-down list and type in the hostnames plus the IPv4 or IPv6 addresses of the email servers which will be permitted to send emails from your emails. As an additional option you may also restrict the messages to be sent from your domain only when it has our MX records, in other words when our servers manage the e-mail addresses for it, not some third-party provider. This option offers you the top degree of protection, but it is not applicable when only your site is on our servers while the emails for the domain name are managed somewhere else. Either way, the SPF protection service will keep your emails risk-free from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

If you host your domain names in a semi-dedicated server account from our company, you can use the SPF protection feature as part of the conventional group of services that you will get using this kind of hosting. Activating the protection involves only several easy steps in the Hepsia Control Panel, so that even in the event that you haven't employed this kind of function before, you won't have any kind of troubles. Employing a really easy to work with interface, you'll just have to enter the information of the mail server which will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly created record propagates, nobody will be able to fake any email for that particular domain and send e-mails from a server different from the one you have typed in. This does not specifically have to be our mail server, however when we take care of your e-mails, you can allow an additional level of security by choosing an option that email messages can be send out from addresses @your-domain.com only in the event that the domain employs our MX records. Our technical support crew will be able to help you 24/7 in case you have any questions about this service.
