[Dovecot] Failing to share folders when listescape is enabled (2.0.14)

8 Nov 2011

      Hello,
How I can share a folder with dots when the listescape plugin is enabled?
In this example user001 is sharing two foders named "docs-abc" and "docs-a.b.c" to user002.
The first folder (without dots) is seen by user002 but the second is not found by dovecot because it search a system folder named ".docs-a.b.c" but the system folder is ".docs-a\2eb\2ec"
