Can't import a mbox file.
I recently restored from a backup after a disastrous crash and was able to restore all accounts and mailboxes in Mail except one. It appears as a mbox file (Unix executable file) in the INBOX.mbox folder and I can see the messages and headers if I double click it and it opens in TextEdit. But I can't get it to import using the File-Import Mailboxes method: I've tried it as both "Mail" and "Other" when prompted for the type of app., and I've selected every folder up the tree from INBOX to Home. In the same INBOX.mbox folder is a Messages folder and those get imported, which are just messages received since the crash. How can I get Mail to see this mbox file? Or can I do something else to import it?
