"biz@6x6" has just about as much mail bounced from my system as all the
other shithead spammers put together (oh no, luckysurf.com gets that
honour). In short (I use postfix not sendmail, so I am guessing here)
it sounds like sendmail won't accept mail from fake domain
addresses according to  it's rule-sets as set up out of the box
on FreeBSD. I would be happy if I were you.
