[Dovecot] minor public folder problem still in v1.0.0

This minor problem still exists in the current version.

It's my own fault, I kept meaning to test one of the latest versions before the 1.0 release and never got around to it. Oh well, just mentioning it so it stays on the list of things to do.

1.0.0 update from RC15 went smoothly here.

Thanks, Mark Nienberg
