Sort-of. Have a look at reply_goes_to_list : although that's really
not going to help keeping replies on list (and i'm of the view that,
except for announcement lists, what goes to the list should have
replies coming back to the list).

Nor will that necessarily help people in creating new threads. I don't
think that's the right approach to your problem:

So, why not take preventative action, in this respect? 

You may want to investigate creating an ACL to raise the threshold of 
hostility for email addresses that aren't from list-members, for
example (it's not something I do, mind: the majority of the -owner
mail for me goes into RT, where I use a queue for training my
SpamAssassins and Bayesian filters, and then out to my mailbox, for
further fine-tuned processing.). 

That (spam-detection/handling) is something to tackle at the MTA
*before* mail gets sent to Mailman. See previous list discussions on
tackling spam at the earliest stages.

Some sort of Bayesian filtering on list-owner mails, that's fed back
could be useful, too.

AIUI, some people have found

to be useful.

Security is *not* the same as obscurity.
