Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to appear as being sent from another one, often with the objective to scam the recipient in some way. If SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all the DNS servers worldwide have it. The record contains all the email servers that are allowed to send valid messages from an e-mail address under the domain. When a message is sent, the first DNS server it encounters verifies the SPF record and if the sending server is permitted, the message is sent to the targeted destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message won't be sent and it'll be removed. In case you employ this solution, it will prevent third parties from sending spam that seem to have been sent by you.

SPF Protection in Shared Hosting

The SPF protection function is accessible by default with each and every shared hosting plan that we supply and you're able to use it with ease to protect the e-mails for any domain hosted within your account. The service is controlled through the Emails section of the advanced, and easy to work with Hepsia Control Panel. All you need to activate the protection is to type the IP address of the e-mail server and its hostname - mail.server.com, for example. As soon as the protection is activated, only this server will be able to send out emails from email addresses generated under the domain name that you've selected. Your email addresses may be taken care of by some other company, but when we handle them in addition to your website, you may also enable an option for your e-mails to be sent only when the domain features our MX records. This feature will provide you with improved protection as only our server will be permitted to send out messages from your mailboxes and you will have better control.

As an extra option, we'll also give you the ability to limit your outgoing email messages and secure your mailboxes further by allowing email messages to be sent only when the domain in question has our MX records i.e. the e-mail messages for the domain name need to be handled here and not by some other company.
