Actually, also it seems to need the copying to happen using the slow way of saving a new mail. With Maildir this means either maildir_copy_with_hardlinks=no or if the source and destination Maildir directories' permissions aren't the same (e.g. both aren't 0700 permissions, or they have different groups). _______________________________________________ dovecot mailing list -- [email protected] To unsubscribe send an email to [email protected]
