one strange problem in mutt

[bing yu <byu@mail.sim.ac.cn>]

i have installed wvHtml and it works

~/.mailcap 
application/msword; wvHtml --charset=gb2312 %s - | lynx --dump -stdin;
nametemplate=%s.html; copiousoutput
text/html; lynx --dump %s; nametemplate=%s.html; copiousoutput

~/.muttrc 
set implicit_autoview = yes
auto_view text/html application/msword 

the problem is: 

when i attache a MS doc file in my outgoing mail. the doc file can
display properly in mutt 

but mutt can not display doc when i got doc attachment from others.(as a
matter of fact, this application is really important  to me, say, i want
say what the document my peers sent to me is ) 

anyone can give me any tricks?

thank you.
