I found a problem when using VM-mail.  To recreate it, you need
ange-ftp and dired from Sebastian Kramer.  To recreate the problem:

Dired a remote site 
try to send a message with vm

While you are typing your message, you will get the following error in
the minibuffer:

Autosaving ... error! for *VM-mail*

What is happening is the autosave is trying to use the remote site.
Looking at the *ftp XX* buffer, you will find:

ftp> delete #%*VM-mail*#
550 #%*VM-mail*#: No such file or directory.

This same problem does not exist if I use the normal emacs mail
function however, so I believe it is a problem in VM.

I am using: emacs 18.55.5, dired 5.87, ange-ftp 3.89, and VM 5.31.
