Sender Policy Framework, or SPF, is a verification system, that is used to prevent the so-called email spoofing where an email message can be sent from one email, but to look as being sent from a different one, usually with the idea to fraud the recipient in some way. When SPF protection is enabled for a domain, an exclusive record is created for it in the Domain Name System and all DNS servers globally receive it. The record features all e-mail servers that are allowed to send authentic messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and when its sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server is not present in the SPF record for the particular domain, the e-mail message will not be submitted and it will be removed. When you use this solution, it'll prevent third parties from sending spam that look as if they have been sent from you.

SPF Protection in Cloud Hosting

The SPF protection option is available by default with each cloud hosting plan that we offer and you're able to use it without any difficulty in order to secure the e-mail addresses for each domain hosted within your account. The service is operated through the Emails section of our state-of-the-art, albeit easy-to-use Hepsia Control Panel. What is needed to enable the protection is to type in the IP of the mail server in addition to its hostname - mail.server.com, for example. The moment the protection is active, only this server will be able to send out messages from emails made under the domain that you've picked. Your email addresses may be taken care of by some other company, but in case that we manage them together with your site, you may also activate the option for your messages to be sent only if the domain has our MX records. This selection gives you even better protection as just our server will be approved to send email messages from your mailboxes and you'll have improved control. When you have any questions or in case you have any kind of problems with this particular service, you can contact our technical support crew at any time and they will give you a hand right away.
