But you probably don't need to mung the reply-to, at least for the
sublists. Assuming no reply-to munging at all, the original post will
always be From: the OP and To: the umbrella. Thus reply will go to the
OP and reply-all to the OP and the umbrella, just as for a
non-umbrella case.

If you want to mung a reply-to, munging the umbrella to reply-to the
umbrella should suffice as that reply-to will pass through the
sublists unchanged.

The only place you have a problem is if the member's MUA offers list
reply based on the List-Post: header. This then may go to that
member's sublist only. The answer to this is to set
include_rfc2369_headers or at least include_list_post_header to No on
the sublists.
