dovecot - Nov 2011 - Failing to share folders when listescape is enabled (2.0.14)

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"

Sorry, doesn't work in v2.0 and I don't think it's possible to fix
it without major changes. Those major changes are done in v2.1 code tree though,
and it works there.
