Changing 'FROM" field on reply

I am using a very simple recipe for acknowledging receipts for a project
I am handling.

This is the basic receipt:

              :0 h c
              * !^FROM_DAEMON
              * !^X-Loop: your(_at_)own(_dot_)mail(_dot_)address
              | (formail -r -I"Precedence: junk" \
                  -A"X-Loop: your(_at_)own(_dot_)mail(_dot_)address" ; \
                 echo "Mail received.") | $SENDMAIL -t


The problem is that it always uses this as the from in the reply
message:

Charlie Root <root(_at_)foobar(_dot_)net>

How can I configure it to use a specific address?

Thanks!
