I use Heirloom-mailx, which is not listed there. It uses bottom posting, and has no support for HTML.

The recommendations they mention are good ideas, although I might also add a few more:

- Allow the sender to prefer purely ASCII when applicable. (ASCII should not be mandatory (since you may want or need to use other character sets for other languages), although it should be possible to prefer it. This can also improve compatibility with the receiver.)

- When forwarding or replying to a plain text message, the reply should also be plain text by default.

- When the author of a message attaches a picture to a message and includes it inline in the HTML message, use a placeholder when converting it to plain text to make it clear to the receiver that there is a picture attached.

- Allow signatures to be disabled, and if a signature is added, then in the plain text format it should precede the signature by a line with two hyphens and one space.
