  Hello Nicolas and everyone else reading. Sorry for the late reply, it
took some time and edebugging for me to understand the problem.

  1) in summary: it was a mail-mode "fault", not Org's. Or better:
     it was my fault, not knowing in depth mail-mode.

  2) in detail: when you create a #+BLOCK_SRC mail and fontify it with
     M-x org-src-fontify-block RET, a buffer is created with name
     " org-src-fontify:mail-mode" (notice the initial space character).
     This buffer usually have a buffer-local variable
     `buffer-offer-save' set to nil, but mail-mode forces it to t. That
     doesn't seem a wrong workflow: you don't accidentally lose the mail
     you just composed.

  3) lesson learnt: you can't fontify whatever you want in a SRC block.
     Some modes work perfectly, some don't, some "almost" work (like
     mail-mode).

  4) future plans: I'm now curious and I'll probably try fontification
     of whatever mode I can think of (M-x apropos RET -mode$ RET) :)

Thanks for your time and attention, kindest regards.

Andrea
