As you may know, email is thirty years old and its underlying infrastructure was never built with security and accountability in mind. No one ever thought that email would become as widely used as it is today, that the Internet itself would be subject to so much abuse.

The original email and Internet systems that we know today weren't invented by Al Gore, but by our own government missile defense system group called the Advanced Research Projects Agency (ARPA), whose primary job was to handle research for all space and strategic missile research. NASA was then formed, and the activities of ARPA moved away from aeronautics and focused mainly on computer science and information processing.

One of ARPA's goals was to connect mainframe computers at different universities around the country so that they would be able to communicate using a common language and a common protocol. Thus the ARPAnet -- the world's first multiple-site computer network -- was created in 1969. In order to have an account on these systems you simply asked for one and they just gave it to you almost without ANY questions, completely overlooking security and accountability.

Well, obviously, as time went by and the systems got larger and more interconnected, some people figured out the vulnerabilities and started to send out the first of many billions of unsolicited messages now known as SPAM. The question now comes down to how we can possibly patch a hole this big. Email authentication technologies like DKIM (DomainKeys Identified Mail) are a start.

DKIM is a signature/cryptography-based sender authentication protocol developed in order to address the problem of forged email messages (missing security and accountability) and to allow an organization or individual to take reasonability for the message it sends, which has given rise to the concept of email reputation. Now, I won't bore you with the details of email reputation and authentication, but I do want to focus on why we got involved in this early on.

Email is now about as mainstream as any technology can be, yet the viability of email is continually being threatened by viruses, spam, spoofing, and phishing. All of these threats are shaking the confidence in email as a viable tool for communications and conducting business, and StrongMail is committed to help protect it. We have been participating in the DKIM standard since day-one, and we are proud to have our own employees acknowledged for their hard work in the standard.

StrongMail was the first technology provider to integrate support for all emerging authentication protocols into its outbound email products to simplify compliance with whatever standards are mandated. DKIM has since gained a lot of traction, and AOL, GMAIL, and Yahoo! now use it successfully in production.

Unless you're a member of the CIA, a Matrix super fan, or a cryptographic expert, signature-based authentication can be difficult to understand. In StrongMail, you don't have to think about any of that stuff, since we make it as easy as 1-2-3 with our step-by-step interface, which will either create, upload, or use the existing keys needed to properly sign and verify any email.

In fact, StrongMail is specifically designed to make it easy to work in the complex and ever-changing world of email standards. You even have the ability to apply authentication to certain email streams or campaigns based on your needs. Our offering is so simple that anybody with a mouse, keyboard, and monitor can institute email authentication.

Overall, DKIM brings accountability to the sender, establishes a reputation and confirms whether they should be sending email from a certain domain. By doing this, receivers can better separate mail streams from those who are good and those who are bad, which enables better anti-spam technologies and reduces false positives.
