You should probably fix bounce messages independently of how you dispose
of spam. Your problem is a sendmail issue and there are far better
resources than the SATalk list for getting Sendmail configuration
advice.
Having said that, the following may be what you need (add/change the
relevant lines in /etc/sendmail.cf):
# my official domain name
# ... define this only if sendmail cannot automatically determine your domain
# Dj$w.example.com
Djsample.example.com

The anecdote from 8/24/2002 on http://www.linux.org/about/spam.html

Rather, find some way to summarize To:, From:, Subject: and (possibly)
the first few lines of textual content, passing that on to the recipient
with a note saying the message was blocked and that the recipient should
contact the sender to set up some alternate means of delivery.
MIMEDefang does that with infected and disallowed files. If you need to
accept and discard spam but alert *someone* that the message was
dropped, alert the recipient, not the alleged sender.
