Emacs Should Support HTML Mail
This article suggests that it is a good idea that emacs's mail facilities (rmail, gnus, vm) support receiving and reading HTML mail.

HTML in email is a very good thing.
From the social point of view, HTML is also far more useful, and people want the ability to have colored text, embed images, attachments. I don't have stats on this, but it is my guess that some 80% email traffics today, are in HTML. Human animals, collectively, want it.
Arguably, another format, such as RTF that WAS espoused by Apple computer's email software Mail for a number of years in the early 2000s, is a better tech than HTML for rich text in email. But for whatever social reasons it didn't catch on. Html is the de facto standard today for rich text in email.
Also, as i mentioned before, tools used by tech geekers usually have 5 or more so years lagging in catching up with any tech that are being adapted in the commercial world. For example, HTML email has basically became the standard in Microsoft since maybe 2002, and HTML is widely supported or in fact default format for commercial web based service provider since many years ago too.
Convenient Wikipedia links: HTML e-mail.
Tech geekers often have a irrational fetish towards plain text email. I wrote a essay back in 2002 detailing my thoughts on this: See: Plain-Text Email Fetish.

Priority Of Adapting HTML Mail
I believe that emacs should adapt the ability to send and receive HTML mail, however, i do not think it is a priority. The above essay was originally just a spontaneous discussion on “gnu.emacs.help”.
Among emacs's potential improvements, there are several that are far more easier to fix and has far more impact than the ability to handle HTML mail. For example, see Modernization of Emacs.
Even if we were to put priority on improving emacs's email feature, it would be far more pertinent to create a robust interface for web based email, because, today vast majority of people reads email online with mail service providers such as Google Mail, Yahoo! Mail, Microsoft's Hotmail, using a web browser. Few are actually using a standalone Email client. Among programers, there are even fewer who actually still use a text-based email client. Most people who uses emacs do not use its email client features.
