Support for Mail-Followup-To header
Please consider supporting the Mail-Followup-To header as discussed here: http://cr.yp.to/proto/replyto.html
This header is used by people who don't wish to receive duplicate mail, and Evolution's lack of support for this header would help stop follow-up mistakes.
As a friendly reminder Branden Robinson of the Debian project expresses it this way via a form letter:
"Many people, myself included, use the Mail-Followup-To message header, which is honored by mail user agents such as Mutt to control the distribution of replies to mailing lists; using such a header, a person can easily indicate that he does (or does not) want to be send copies of replies to his message. You may want to use an MUA that honors this header, as it is in fairly wide usage on the Debian mailing lists, and may help you avoid mistakes resulting in inadvertent violations of Debian's Mailing List Code of Conduct."
