I personally wish I could have stuff look to the recipient the way I want when I send email, but I have long since given up on that idea. The person receiving the message may not have the font I like on his machine, and unless you send a .pdf file, you don't have real control over formatting anyway. Plain text is adequate for the purposes of this list, and it's universal. That, folks, is my opinion and the reasons for it.

Ah, but modern design/manufacturing philosophies require re-use of standard components in order to minimize the carrying costs of 9 bazillion different components, and in order to leverage lower costs in volume purchases of standard parts. For different reasons, everything old is new again....

The only universal truth in e-mail is plain text, ISO8859-1. Anything else is a system administrator's headache that can't be won for trying. Problem no. 1: what one GUI mail user agent (MUA) considers "HTML" another MUA considers garbage. When you've got a thousand or more recipients, the only way to send readable mail to most of them is plain text. Problem no. 2: An HTML version of a text message increases the byte count by a factor of at least two times, and often, four times. That's a whopping increase in mail traffic for both the sending and receiving sites for absolutely no change in information content. Problem no. 3: A lot of the large ISP's treat all mail list mail as spam, and several simply silently discard it, rather than bouncing it or letting the recipient know. HTML-only mail is a "spam" red flag in addition. I've swapped notes with Jack about the configuration used on this list, and if we agree on anything, it's that any change is for the worse. There are alternatives to simply trapping other formats than plain text and attempting to convert them to plain text. Altogether too often, the result is unreadable. The above doesn't address the problems created by attachments, which are also humungous for a mail list setup. The average post length (in ascii plain text) is around 2-3K bytes, yet people think nothing of sending 5-10 megabyte attachements to mails. Multiply that by the size of a mail distribution list, and you're talking gigabytes, not megabytes.

Quite right. That is why standardized values need to be logically useful. But that didn't stop component manufactures from coming up with new parts! Hence, more computing needed!
