Use the correct means of exiting emacs, perhaps. The key sequences I
have used (^X^S^X^C, and the same keys but using ^Q shortcut) will
work if the emacsclient instance is in a different frame from the
emacs server. Because I use emacs -nw for composing emails¹, and the
server was running in a different xterm, it all worked.
OTOH if you're using emacs in its own window, then typically your
email composition will jump to that same window too. In which case,
typing ^X^C will shut down the emacs server itself. You should be
using ^X# instead, to exit just that buffer. So for you, it would be
(global-set-key [?\C-q] "\C-x\C-s\C-x#")
for the definition. ^X# is meant to signal the calling program that
it's completed its editing work.
¹ Why? For historical reasons. I used to type emails on a slow,
unreliable laptop, with mutt running on a server. Opening an X
window for emacs was also slow, so I ran it non-windowed.
Cheers,
David.
