As I mentioned I already read that, and the mailing list postings. It
doesn't make me any wiser though :-(

What would the expected behaviour be of modifying the UID as cached by
offlineimap?

I did the following:

 1. Turned off fetchmail on the server.
 2. Cleaned out the cached UIDs as described in the manpage on the
    client
 3. Ran offlineimap --> no errors
 4. Ran offlineimap again --> UID invalid on one box
 5. Modified the cached UID value in ~/.offlineimap/Repository-<remote
    location>/FolderValidity to hold the value that offlineimap reported
    getting
 6. Re-ran offlineimap --> UID invalid on the same box

Output:

 therning@pc67148596[~].$ rm -rf .offlineimap/Repository-work_rem
 therning@pc67148596[~].$ offlineimap

As you can see the UID it got changed (the values were swapped).

Idealism is fine, but as it approaches reality the costs become
