With Windows your options are mailclient-send-it and hope for the best
or configure smtpmail-send-it to work.  (This is one item on a very long
list of things that caused my most recent move back to Linux.)

It does seem lame that it's not looking for Safari, but then I don't
know if it looks for IE on Windows.  This may be a philosophical point
and not a technical one, so for better or worse it just might not
happen.

I think a case can be made that tampering with a browser-oriented thing
shouldn't break an email-oriented thing when it is not obvious to the
end user that that's what's going to happen.  A case could also be made
that if one knows how to tamper with browse-url, they know how to
configure smtp mail correctly.

I don't think this is so much that browse-url is brittle, just that a
case can be made that it should work for the more defaulty browsers.
The overall issue of having Emacs get the right answer to "What is your
mail client?" might still ought to be addressed in a way that doesn't
rely on browsers at all, which may be more possible now than it was
however long ago.
