The above line is wrong.  Get rid of it and its terminating close parenthesis.

I still don't understand why that hook function can't be added until after
sendmail.el is loaded, though.  The hook variable is quoted, as is the function
(twice actually: once by lambda, and once unnecessarily by the quote character).


= You can find that yourself; just do: `C-h v mail-mode-map RET' (or any
= other variable you're interested in).

Sometimes that works with this variable, other times it doesn't.  My
almost educated guess is that it depends on whether or not I've first
opened a mail session (M-x mail).

The variable is defined in sendmail.el, which is not dumped into the
emacs executable.  Nor is the variable marked with an autoload cookie,
which would have gotten it included in loaddefs.el and dumped into the
executable.  So it is not defined until sendmail.el is loaded, which
happens when one of its autoloaded functions is called, e.g. the mail
command.
