Thunderbird does not really seem to like quoting code...  This now was a
mixed HTML/plain text mail.  The plain text version looked actually
fine, so it is not quite clear why you would need a combined mail just
to get the correct plain text version out.  The HTML rendition here used
non-breakable spaces...

Then you should not be using a mark.  If you want to be using a
textscript, this is actually more fun to do with current versions of
LilyPond (2.15.not-too-old). It would look something like

fN = #(define-event-function (parser location fretp ) (string?) 
    #{ 
        _\markup { \box \italic \small #fretp } 
    #})

The closest you can get with 2.14 is something like

fN = #(define-music-function (parser location fretp ) (string?)
  (make-music 'TextScriptEvent
              'text (markup #:box #:italic #:small $fretp)
              'direction DOWN))

if you are lucky, and even then you will have to use it as

-\fN "whatever"

rather than just \fN "whatever".
