Hi,
unfortunately I found a bug in Dovecot's ACL handling for shared mailboxes. It turns out Dovecot doesn't enforce lower casing the privileged username to whom the mailbox should be shared to. This results in a invalid configuration. Users get confused, since they passed on a valid email address in their ACL setup.

user=Leander@MyDomain.LocalDomain eilrwts ^^ Doesn't work
Best regards Leander Schäfer
Hi! Did you know you can use %Lu instead of %u to force lowercasing?
