Hi,

I had some trouble with ACLs not being copied to new child mailboxes in dovecot 2.2.4. It doesn't matter whether it's a private, shared or public mailbox I create the folder in, the ACLs just seems to be ignored. Anyway, I debugged the executable and came up with the attached patch. Since I'm not a developer, I'm not 100% sure about this but it works for me now.

Regards, Markus
