Permissions on the files and > directories are correct. Can you list the mailbox file? [are you sure it isn't a permissions problem] A much better option is to use cvt_cyrusdb on the running server to convert the databases to skiplist and then use those databases over on the new server. Generally people have migrated away from BDB [in large part because of issues like these; getting a reliable build environment is tedious].
