"How do I change the header so reply goes to the list
rather than to the sender of the message"

That is dealt with on page 183 of the listowner's
manual.

Because there are some serious caveats with changing
it from the default, you might want to read that
section before making changes to your list.

That said, the pertinant line is the Reply-To=

The defult is Reply-To= List,Respect

Which should give you the result you want, and being
the default "should be" the safest way to go.
