Stupid Sendmail tricks?

[John White]

On a mailing list I administer, bounces from a subscriber go
to the person in the From: header.  The subscriber is from
leisureworld.org, who's mx is mail.pajo.com

bash-2.03$ telnet mail.pajo.com 25
Trying 216.116.96.4...
Connected to mail.pajo.com.
Escape character is '^]'.
220 mail.pajo.com ESMTP Sendmail 8.9.1a/8.9.0; Mon, 15 May 2000 20:35:17 -0700 Hello


Is it really possible to configure Sendmail 8.9.x to bounce messages
to someone other than the envelope sender?!?!?!?!
