SPF, which is short for Sender Policy Framework, is an email security system, which is designed to verify if an e-mail message was sent by a licensed server. Employing SPF protection for a given domain will stop the counterfeiting of email addresses made with the domain. In layman's terms: activating this feature for a domain name makes a special record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send email messages from mailboxes under the domain. When this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Any time some e-mail message is sent, the first DNS server it goes through checks whether it originates from an accredited server. If it does, it is forwarded to the destination address, but when it does not originate from a server indexed in the SPF record for the particular domain, it's rejected. Thus nobody will mask an email address to make it appear as if you're distributing spam. This approach is also called email spoofing.
SPF Protection in Cloud Hosting
The SPF protection function is provided by default with each cloud hosting package that we supply and you are able to use it without any difficulty so as to secure the e-mails for any domain hosted in your account. The service is managed through the Emails section of the cutting-edge, albeit easy-to-navigate Hepsia Control Panel. All it takes to activate the protection is to type the IP of the mail server in addition to its hostname - mail.server.com, for example. When the protection is activated, only this server will be able to send emails from e-mails generated under the domain name that you've selected. Your email addresses can be managed by another supplier, but in case that we handle them together with your website, you can activate the option for your email messages to be sent only if the domain features our MX records. This option gives you better security as solely our server will be authorized to send e-mails from your mailboxes and you will have better control. If you have any kind of questions or if you have any sort of difficulties with this service, you will be able to contact our tech support team anytime and they'll assist you immediately.
