Not sure if you are having the same problem I had or not, but after having the same message and looking at my logs I found the issue was with Dovecot. I did an update of the system and something with Dovecot changed. Namespace issues. Here is what I did:

edit /etc/dovecot/dovecot.conf using vim/vi/nano (whatever you prefer)

Add the following:
namespace inbox {
inbox = yes
}

I can't say for sure this is the same problem you are having, but if you check your dovecot.log (/var/logs/dovecot.log) and you see the below error messages then try out that fix.
