I love the ZWC, but there are a couple of problems that stop me wanting to use it to post on mailing lists -- especially the kind of mailing list where users are pedantic about list etiquette. What's important is that people are not distracted from the message in the email I send by strange formatting. Mutt, for one, seems to make a point of helping its users shame senders of unconventional mail by putting bold red symbols on the beginning of every line which it must soft wrap.

A plain text email should wrap lines before sending the message. How do I make the ZWC do this?

A mailing list email should never be top-posted. How can I make Zimbra bottom-post, so I can reply to individual points in an email?
