This isn't what you want to do. If you did, all email sent from your
domain to other domains would go to/through the web server.

If it doesn't reach an account that accepts it, it bounces.

It doesn't work that way. Mail is either forwarded or not. You can route
based on the message headers, body, etc., but not on on whether the
first delivery attempt succeeds.
The solution is to create a dns entry for the web server called
'lists', so that all of your mailman lists have addresses like
somelist@lists.yourdomain.com
Now your main email server is entirely out of the loop for all mailman
traffic. The only exim configuration work (other than the mailman
modifications) is to make sure that the list server accepts mail
addressed to 'lists.yourdomain.com' as local mail. This should be easy,
done right at the top of the exim.conf file with a declaration like
local_domains = localhost:lists
