Suppresss "~/Mail does not exist" in mutt

I use Mutt (1.5.21 on a headless Debian 7.2 Wheezy VPS) only occasionally, to see and delete messages from cron and the likes. However, it keeps pestering me with this non-existent ~/Mail folder. No need to say that it works perfectly with the folder not being created; I'm kind of miss the whole point of asking this every time. Can I disable the message? (Or if that fails, change the path to something invisible?)
