Hello everyone,

right now I have problem and can't find a proper solution.

But first: dovecot-version: 2.2.13

Now to my problem: A client of mine uses a public folder called "groups". In this Folder are several subfolders like "Archive", "projects", "sales" und so on. Unfortunately this client (and his employees) created thousands of subfolders within these folders. The folder "groups" is stored in /data/vmail/domain.com/.

So, if i type "tree -a -L 1 /data/vmail/domain.com/groups" I get the following outpout:

/data/vmail/domain.com/groups/ ??? .Archive ??? .Archive.subfolder1 ??? .Archive.subfolder2 ??? .Archive.subfolder2.subfolder3 ??? .Archive.subfolder2.subfolder4 (....) ??? .projects ??? .projects.subfolder1 ??? .projects.subfolder2 ??? .projects.subfolder2.subfolder3 ??? .projects.subfolder2.subfolder4 (...)

In this groups-folder are at the moment more than 3400 folders!

Now to the permissions: When the folders "Archive", "projects" and so on had been created every folder got a dovecot-acl for the permission for each user, e.g.: user=user1 kxeilprwts user=user2 kxeilprwts

This worked finde, as the dovecot-acl got copied from the parent folder when the employees created new subfolders.

Now to my problem I'm facing right now: This client got 2 new employees. So how can I edit all these dovecot-acl files in all subfolders where these 2 new employess schould get access to?

Thank you in advance! Yours sincerely, Lukas Henrich

Furthermore here is the output of dovecot -n:
