Dovecot 2.2.20 autoexpunge

I have configured autoexpunge on some folders:

namespace inbox { inbox = yes location = mailbox Junk { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 2 weeks special_use = \Trash } prefix = separator = / }

After adding these and restarting, logging in and out several times, I still see messages days/weeks past the autoexpunge setting. I checked the logs but never see any autoexpunge messages logged. Is there something else that needs to be set to trigger this?
