I found another place where the QUIT ACL may possibly want to be called
but I had reservations about it when I spotted it. Unfortunately we've
been preparing for a trade show ever since I did that patch so I haven't
been able to change it and test it. So far, the rest of the patch has
been running on my mail.linuxwan.net server without fail.

The function void smtp_closedown(uschar *message) (smtp_in.c - line 720
in mine) is another function that sits in a loop waiting for
disconnection or QUIT. It probably needs to call both the QUIT ACL and
not-QUIT ACL when EOF_CMD and QUIT_CMD occur. As soon as that function
returns, the thread is seems to be terminated hence the reason for
calling both. I can throw it together but if you've already cleaned up
my code then whatever I add will probably just snuff it all up again.
