since you use mutt you can, there is a
setting for that:


# set followup_to=yes
# Type: boolean
# Default: yes
#
# Controls whether or not the "Mail-Followup-To:"  header  field
# is  generated when sending mail.  When set, Mutt will generate
# this field when you are replying  to  a  known  mailing  list,
# specified with the "subscribe" or "lists" commands.
#
# This  field  has two purposes.  First, preventing you from re‐
# ceiving duplicate copies of replies to messages which you send
# to mailing lists, and second, ensuring that you do get a reply
# separately for any messages sent to known lists to  which  you
# are not subscribed.
#
# The header will contain only the list's address for subscribed
# lists, and both the list address and your  own  email  address
# for unsubscribed lists.  Without this header, a group reply to
# your message sent to a subscribed list will be  sent  to  both
# the list and your address, resulting in two copies of the same
# email for you.


Since "yes" is the default, either you
do not teach mutt which mailinglists you
are subscribed to, or the mail user
agent of the people answering is
ignoring it (or the mailinglist software
is throwing this header away).


Ciao; Gregor
