You could modify the script. I.e., make a new script remove_banned.py
which is a copy of add_banned.py with every occurrence of 'add_banned'
replaced by 'remove_banned' and the line

    mlist.ban_list.append(address)

replaced by

    mlist.ban_list.remove(address)

Also, You may be interested in the GLOBAL_BAN_LIST implementation to be
in the latest (2.1.21) Mailman release. See
<http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1574>.

Further, in the ban_list (and many other places in Mailman) if an
address is intended to be a regular expression pattern, it must begin
with '^', so you really want

^.*@domain\.com$

to match any_address at domain.com.
