It works fine from a shell (without a window-system) and on other  
systems (as long as the defined mail client, i.e. mailto:// URL  
handler doesn't require one).  That is, provided the function  
`message-send-mail-function' is only used to initialize the variable  
of the same name. The default should be `mailclient' only on specific  
systems - at least on Windows and probably on the Mac as well.   
Reiner should know more.
