My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder.

running dovecot -n produces the following:

1.0.10: /etc/dovecot/dovecot.conf

umask: 511

511 decimal = 0777 = created files have permissions set to 000.
