Coding system for outgoing mail

[konrad.hinsen@laposte.net]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars)

configured using `configure  i386-redhat-linux --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --with-gcc --with-pop --with-sound'
Important settings:

  value of $LANG: en_US
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Since I set up my Emacs for international character set support,
every time I send a mail with non-ASCII characters I have to specify
the latin-1 coding system manually. According to all documentation
I could find, it should be sufficient to set sendmail-coding-system
to latin-1 to have outgoing mail sent as Latin-1 by default, but that
doesn't work.

After a lot of searching, my hypothesis is that something sets the
local value of buffer-file-coding-system to binary for every new mail
buffer. So I added the following to my .emacs:

 (add-hook 'mail-mode-hook
	   (function (lambda ()
		       (setq buffer-file-coding-system 'iso-latin-1))))

but that makes no difference either.
