Re: rmail passing movemail an option it doesn't like

[Richard Stallman]

    I managed simpler: <quote>

    emacs -q --no-site-file
    M-x rmail

    </quote> and reproduced the error !

    So I'll hazard a guess that your movemail variant is emacs and my
    problem is actually incompatibility with the mailutils one.  Here's
    the whole of my *Messages* buffer for that session: <quote>

Can you use the debugger to determine precisely what options
Emacs passes to movemail?  You could do debug-on-entry
for call-process.
