RFC 822 was published in 1982. There have been some minor refinements, and RFC 2045-49 (Multipurpose Internet Mail Extensions - MIME) attachments were added in 1996. Several proposals were written for secure email (PEM, S-MIME), but none ever broke through. A great deal is left to software-writers, and no significant, standardised upgrades have been forthcoming.
Why not? Probably because there's too little incentive to innovate, because so much of it has to be open standards and hence advantage can be quickly competed away. For example, Eudora was passed into the public domain some years ago, because Qualcomm could see better ways to make money.
The many forms of IM have become the text-messaging services of choice for vast numbers of the people who began using the Internet after about 1998.
The ISPs who continue to use the 'walled-garden' business model try to avoid providing inter-operability with their competitors' IMs; and hence many people want you to 'join Facebook', or whatever their current preferred SNS might be, or be reachable on Skype Voice / Video / IM. Those are popular with Gen-Yers, but for iGens the text-messaging service of choice is SMS.
There's been no scope for a standardised security solution, because:
People don't make reasoned decisions to adopt eCommunications products and services. Their decisions are made based on convenience and fashion, augmented by peer-pressure.
Even if people listed their wants and don't-wants in eCommunications products and services, security would be a very low-priority feature. That's because threats are non-visible and hard to understand, and hence people have (unwarranted) comfort.
Not just people, but also many organisations, exhibit very low awareness-levels of security threats, vulnerabilities and consequences. Here are some examples.
Many corporations do not require and support security for their staff while on the move (although some do impose links via a VPN, encrypt data on the disk, auto-encrypt to external devices, etc.).
You'd expect whistleblowers to take great care to protect their identities. Postings to Wikileaks have been sent using TOR (The Onion Router), which uses multiple proxies to anonymise the source of a message. But some files sent through TOR have been unencrypted. So the exit node from the TOR chain has been aware of the file that has been sent to Wikileaks, and when. (And the entry-node to the TOR chain has had access to both the content and the sender!).
It's a concern that even one person who is taking considerable legal, financial and personal risks in leaking documents fails to understand the openness of 'postcards'. But it may be that multiple people who have posted to Wikileaks have done so without encrypting the content.
Naive 'newbies' dominate text-messaging and image-transmission between mobile-phones, and are surprised when their misbehaviour is publicised and traced back to them.
Gmail users 'just don't get it' when I decline to talk with them except via a real email-address.
Among many other factors in the current lack of understanding is the fact that Gen-Yers grew up in an era when self-exposure was rampant.
But let's be fair - there are a few positive stories.
SSL / https is mainstream, and has been highly successful in protecting sensitive data in transit (although not in authentication). That worked because "it came with the software".
Internet Banking is understood in many societies to require care. The meme does seem to have spread that normal emails and web-forms involve unacceptable risks when you're operating on your bank account.
Virus-detection software has come to be reasonably well-understood by the general public, and there is even some basic understanding of what a firewall is and why people should want one.
As Gen-Yers mature, they are discovering the risks that arise in open eSociety, and they are also steadily accumulating things to hide. A flex-point may come when privacy suddenly seems a lot more important than before. iGens, meanwhile, have seen how naive Gen-Yers have been on Facebook, and are much more savvy. I deal with this at greater length in Clarke (2009). Harbingers include the backlash against Facebook during the first half of 2010, by the media and segments of its user-base. More on that here.
