SPF PROTECTION ENSURES YOUR INTERNET PRIVACY!

[11/24/2006]

This Advanced feature newly introduced to the Web Hosting Control Panel is programmed to give you full access to configuring the outgoing (sending) capabilities of your domain names hosted with us.

Domain names use public records (NS) to point requests for a number of other services such as web, e-mails, ftp etc. The same goes for the MX records concerning exclusively e-mail accounts corresponding to a specific domain name so that the MX record can tell us which computer receives e-mails from which domain name.

SPF stands for Sender Policy Framework, and is an extension of SMTP that is exclusively developed for stopping spammers to act like they are sending e-mails from your domain name even if the e-mail accounts do not even exist. It is frankly put an Authentication system to designate which computers are authorized to send e-mails for a specific domain names.

SPF works by publishing “reverse MX” records to tell the world what machines are authorized to send mail from the domain. When receiving an e-mail message, the recipient can check those records to make sure mail is coming from where it should be coming from. This means that the sender domain is compared to the SPF record for that domain to determine if the e-mail sender is indeed authorized to transmit e-mails from that particular address. If the e-mail comes from a domain that is not authorized, the DNS server will disregard the e-mail request. In other words, SPF prevents people from stealing your e-mail addresses and pretending that it is you who send junk/spam e-mail to other people.

Please note that these settings are for advanced users only!
