I have the following in my sendmail.mc file

LOCAL_NET_CONFIG
# This rule ensures that all local mail is delivered using the
# smtp transport, everything else will go via the smart host.
R$* < @ $* .$m. > $*    $#smtp $@ $2.$m.         $: $1 < @ $2.$m. > $3
define(`SMART_HOST', `mail.wiche.edu')dnl

Local mail is still going to the smart host. Is there anywhere else in the config where I need to define what local mail is?
