using formail with -r & change From:

        I'm setting formail with sendmail to do auto-reply mails.

        I used the solutions following the book Mailing Lists (O' REILLY),
on page 93, putting this two lines in /etc/aliases:

owner-membership.agreement: user
membership.agreement: "|/usr/local/bin/formail -r | /bin/cat - \
/usr/local/adm/msg.test | /usr/lib/sendmail -t -oi"

        If I send a mail to membership(_dot_)agreement(_at_)my(_dot_)domain, I 
receive the
contents of /usr/local/adm/msg.test, from daemon(_at_)my(_dot_)domain(_dot_)

        I would like to change daemon(_at_)my(_dot_)domain to 
any_user(_at_)my(_dot_)domain, is
it possible? How?
