Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail, but to look as being sent from another, usually with the objective to fraud the recipient for some reason. If SPF protection is activated for a domain name, a specific record is generated for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all email servers that are allowed to send authentic messages from an address part of the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is permitted, the message is forwarded to the target destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the e-mail message won't be sent and it'll be discarded. Whenever you employ this service, it'll stop third parties from sending spam that appear to have been sent by you.
SPF Protection in Shared Website Hosting
The SPF protection function is provided as standard with every single shared website hosting plan that we supply and you're able to use it with ease to secure the emails for any domain hosted in your account. The service is controlled from the Emails section of our advanced, yet intuitive Hepsia Control Panel. All you need to enable the protection is to type in the IP address of the mail server in addition to its hostname - mail.server.com, for example. As soon as the protection is active, only this server will be able to send email messages from e-mails generated under the domain that you have selected. Your e-mail addresses may be handled by some other company, but in case that we take care of them in addition to your site, you can activate an option for your emails to be sent only if the domain uses our MX records. This selection provides you with even better protection as only our server will be certified to send out e-mail messages from your mailboxes and you will have superior control.
