check_rcpt is the rule set. A couple of things to check:
1) Does /etc/sendmail.cR exist? It should contain a list of machines
that you wish to allow relaying from/to. It doesn't do wild cards
unfortunately.
2) When you put this ruleset in, did you cut/paste or type it? You
*MUST* have tabs (not spaces) between the LH (R< $+ @ $=w >) and the
RH ($@ OK).
3) After you put this in, did you kill and restart sendmail?
