SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is employed to validate whether an e-mail message was sent by a certified server. Employing SPF protection for a particular domain will stop the counterfeiting of email addresses made with the domain. In simple words: activating this function for a domain name generates a special record in the Domain Name System (DNS) that contains the IP addresses of the servers that are allowed to send email messages from mail boxes under the domain. When this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. When some email message is sent, the initial DNS server it uses checks whether it comes from an accredited server. In the event it does, it's sent to the destination address, yet when it does not originate from a server part of the SPF record for the domain, it is rejected. Thus nobody will be able to mask an e-mail address to make it appear as if you are e-mailing spam. This technique is also referred to as email spoofing.
SPF Protection in Shared Hosting
The SPF protection option is provided by default with each shared hosting plan that we supply and you will be able to use it without any difficulty to secure the email addresses for each domain hosted in your account. The service is controlled through the Emails section of our hi-tech, and intuitive Hepsia Control Panel. What is needed to activate the protection is to type the IP address of the email server plus its hostname - mail.server.com, for instance. When the protection is active, only this server will be able to send out email messages from e-mails generated under the domain name that you've selected. Your email addresses may be handled by a different provider, but when we handle them along with your site, you may also enable an option for e-mails to be sent only when the domain has our MX records. This option will provide you with greater security as only our server will be certified to send out messages from your mailboxes and you'll have better control. If you have any kind of questions or if you experience any sort of troubles with this service, you will be able to contact our tech support crew at any time and they'll assist you immediately.
