What does Mail do here?

    in Console I notice hundreds of logs like the one pasted at the end. It appears that Mail is trying to find an old mailbox (OLD MAIL) that I had imported into Mail a long time ago. As long as I was still on Mountain Lion this wrong behaviour did not exist.

    How can I stop Mail from doing this and to swamp my console with these messages?

    What does "Assertion failure" mean?

    But that old Mail doesn't show in the list of mailboxes (In Mail, under View > Show/Hide Mailbox list)?

    Take a look in your Homefolder's library/Mail folder, there's a subfolder called Mailboxes, see if your 'Old Mail' is in there, and can be deleted.

    That folder can be reached in Finder > Go >Go to folder, then type: ~/Library/Mail/

    Make a backup of the Mail folder (and maybe Quit Mail) before you change something over there.

    Well, yes, I do keep my old mail folders from up to two years just in case I need a message. They are purposefully visible/accessible (under the heading on my Mac). They correctly exist also in the ~/library/mail folder.

    Ah, I wasn't reading correctly, thought you didn't use that old mail folder, and were only bothered by the console notifications.
    But you are still using it..

    What to do? Maybe delete that folder from Mail (after you made a safety copy in Finder) and add it again.
    Or.. nothing. If this is only in the background and not changing your user experience, why bother?

    Usually (but not always :) ) This is caused by the Envelope Index files being out of date, corrupt or otherwise out of sync.

    Deleting them while Mail is closed will force Mail to re-index once you open it up again. It usually solves these kind of issues.

    There will be 3 or more such files in your ~/Library/Mail/V2/MailData folder.
