Yes, exactly. Great for "integrating" legacy IMAP servers without e.g.
ACL support.

Oh, had not realized that a path argument is possible for imapc:. There are
even index file then...

It almost works:
Sep 13 18:37:58 hhh dovecot: imap(4482, uuu): Error: file_dotlock_open(/home/uuu/Maildir/gmail/.[Gmail].Alle Nachrichten
/dovecot-acl) failed: No such file or directory
After manually creating the ".[Gmail].Alle Nachrichten" directory, SETACL
succeeds.
