textwidth -- 

        Maximum width of text that is being inserted.  A longer line will be
        broken after white space to get this width.  A zero value disables
        this.  

If you have 'tw' set to 0 then no wrapping will occur automatically.

In addition, the 'formatoptions' variable controls where automatic
wrapping will be done (see :help fo-table for details on the flags).
For mail messages you'll want to wrap normal text.  For code I have
only comments automatically wrapped.

Also check the filetype of your message.  (":set ft?")  Vim is pretty
good at identifying files as type 'mail', which you can set some
autocommands for.

augroup Mail
    au!
    au FileType mail set tw=70 fo=tcrq2 nomodeline
    au FileType mail set comments+=n:\|
    " clear the old sig and go back to the beginning of the buffer
    au BufRead /tmp/mutt* normal :g/^| -- $/,/^$/-1d^Mgg
augroup END


That last autocommand clears the sig out of the message I reply to
when the buffer is read.  (put a literal 0x0d character in place of "^M").

Some other settings that may be relevant are

" enable the new filetype and indent plugins
filetype on
filetype plugin on
filetype indent on

I don't see the problem.  Did you ":set paste" prior to typing that
line?  Sometimes I set 'paste' so I can paste some already-formatted
text into a buffer, and forget to unset it afterwards.
