Hi,
    excuse me, I'm fairly new to sendmail.. but there seems (to me) to
be an error in /usr/src/usr.sbin/sendmail/cf/m4/proto.m4 at line 447,
where it says (in ruleset 96) something like this:

R$* < @@ $=w > $*       $: $1 < $j . > $3               self-literal

(NB this editor doesn't do tabs)

  I've been kicking sendmail around for most of the afternoon, because
I couldn't get a config file made that accept mail to any of the sites
listed in the w class, but if I change the @@ to @ it works fine..

  It seems to have been this way since 1.0 at least, which makes me
think its ignorant me missing something else..  I include a larger
part of the ruleset below, to put it in context..  any sendmail guru's
know for sure?
