There are several ways to mung list headers so that replies go to the
entire list.  One way is not to change them at all, if people's
mailers are smart enough to be able to reply to all recipients of a
message.  Another way is to add a Reply-to header, but only if there's
not one there already. This allows a list contributor to specify that
replies should be sent to him/her rather than the entire list, if
he/she supplies his/her own Reply-to address with the message.

The error-message address isn't supposed to be determied by headers.
You need to set the envelope from address.  One way to do this with
sendmail is to use the -f command-line option, but you may have to
make sure you are running as a "trusted user".

Since some non-Internet mail paths lose envelope information, you may
find it useful to include an Errors-to header also, but its address
should be the same as the envelope from address.
