Moving read messages to /home/walton/mbox?

[Bryan K. Walton]

When I close out my mutt session, mutt asks me:

"Move read messages to /home/walton/mbox? ([n]/y):"

How can I set my .muttrc file so that it NEVER asks me this and
so that it also never performs this act?
I just closed out my inbox and moved about 200 messages to
this mbox folder that I didn't want to move (due to my being
hasty and not paying attention to what mutt was asking me.

Thanks,
Bryan Walton
