Arrange for the editor to return a MIME message? Right now if you set edit_headers and manual compose a MIME message, mutt wipes out the MIME headers and leaves the MIME parts as garbage in the single text/plain part. But if mutt would examine the message returned from $editor to see whether it's a MIME message, and leave the structure intact if so, that would be a cheap way of allowing people to hook their own MIME composition systems in. People could set $editor to "markdown_mime /path/to/real/editor %s" which would call the editor with what mutt passes, but create a MIME structure with the result before handing it back to mutt. There's some complexity around what to do if $edit_headers is no (look for a minimal MIME structure with only the MIME headers and parts?), how to handle reedits (pass just the text/plain part back to $editor? pass the whole thing including MIME parts?), etc, but better than overloading $sendmail. -- Ed Blackman
