Several months back shared folders based on ACL's were discussed here, and it was mentioned that support for these had been added to CVS.
Since the web site still says shared folders aren't implemented, I just wanted to check and see if the shared folder code is just in CVS for a future, post-1.0 release, or if the code ever made it into any of the 0.99x relases.

There's some very simple support for shared folders in CVS, only to get file permissions correct so that files are readably by file's group (or everyone). That has to be done manually by creating proper symlinks and dovecot-shared file. There's no support for actual ACLs, and it's not planned before 1.0.
