elisp dummy needs help

[rusty@grunt.berkeley.edu]

I've moved to a machine that has a new version of emacs.  When reading
email with rmail when I use the s (save) command it's always asking me
for confirmation.  On the other machine it didn't do this and I prefer
that behaviour.

I looked in the elisp files and found this.  It looks like I can add
something to my .emacs file and make it behave the way I like, with no
confirmation.  Could someone tell me what to add or point me to the
right place in the docs that explain how to do it?  I don't know
elisp.

Thanks.
