[Mailman-Users] How to change configs for ALL lists?

[Bernadette Mooney]

was: Re: [Mailman-Users] unsubscribing addresses from domain in one fell swoop?

We had the same thing here - 900 lists, 120,000 subscribers - but while
the 400-odd bulk-unsubs went well, cleaning out the 'pending' 700 or so
authorisation requests was a little more problematic.  However, 'tis
done now.

The current question is:  How can I change the configuration of ALL lists, to add a line like 
"ban_list = ['^[A-Za-z0-9._]+@[Nn]astymail\\.org' 
or 
"header_filter_rules = [('Subject:.*\\*\\*\\*SPAM\\*\\*\\*.*', 3, False)]" 
or 
add an extra address to the ban_list line?

config_list?  with_list?  but how?

And no, I'm no programmer, just a little quick'n'dirty shell scripting is as much as I can handle.  :(
