You should not let your MX accept mail for non existent recipients. That 
leads to overloaded mail queues for mailer daemons replies and autowhitelist.

You can fix your sendmail configuration, but that may be complicated. I
wrote milter-rcptfilter to filter out invalid recipients without touching 
my sendmail configuration. rcptfilter.conf is autogenerated from our 
directory each time it is modified.
