signature and batch mode.

["Badinter, George" <george.badinter@xxxxxxxxxxxxx>]

My signature seem to be working fine in the command line mode. If I use mutt  
it reads my .muttrc  set signature=~/.signature  and appends the file. However, 
if I use mutt in batch mode
such as - mutt -s Test  george.badinter@xxxxxxxxxxxxx < /tmp/test  - I can't 
make mutt to append a signature file. 

Any ideas?

Thanks

George
