[Mailman-Users] Deleting old msgs?

[Frank Bell]

I've seen a post on one method for removing old msgs involving copying a 
mbox to another location, opening it with a mail client, review/delete 
msgs, and then replace the mbox, run a process.

I'm very very new to mailman, so forgive me.

Is there any easier way? I just took over our mailman server and we have 
several years worth of messages in 190+ mboxs totaling approx 130 gig 
and a few 100K msgs.

Thanks,
Frank
