Well, these are obviously not list headers. :P
Ok, their use is general, but they're intended for use where groups of recipients exists. I feel they are used mostly on mailing lists.
From draft: "This proposal contains a proposed new e-mail header
''Mail-Followup-To'',which is intended to be used instead of the ''Reply-To'' header for suggesting where replies to the group who participates in a discussion should be sent."
I was thinking about removal of Mail- prefix in labels, but then we'll have two REPLY-TOs. FOLLOWUP-TO could be used without prefix (because Roundcube doesn't support NNTP), but it's better to have Mail- prefix in both for consistency.
