#2976: Mutt writes unsolicited "Lines" and "Content-Length" headers
Comment (by rtc): I now uploaded a new patch that introduces the option mboxrd_format to keep these headers from being added. In addition to the previous patch, it does that also on saving FCCs, and I implemented From_ escaping to prevent the issues arising out of this. I did not implement anything concerning unescaping these on reading mailboxes, but it wasn't done previously, anyway. (It might be annoying when postponing a message with From_s). If you want more fine-grained control over whether Content-Length and Lines should be added, please change the patch according to your desires; the necessary changes should be trivial. -- Ticket URL: <http://dev.mutt.org/trac/ticket/2976#comment:4>
