This is probably why you are failing to prevent resync/redownload.

Oh, thanks!

I was simply using rsync to synchronize the control/index directory tree into the maildir, incorrectly assuming the trees were the same in both configurations:

  rsync -uav /mail/{index,control}/${user:0:1}/${user:0:2}/${user}/ /mail/${user:0:1}/${user:0:2}/${user}/Maildir/;

I see now, as you said, that the control and index files for INBOX should be placed directly in the maildir, and that they have been recreated for the users in question.

I'll try modifying the sync part to also move the files from the .INBOX folder:

  rsync -uav /mail/{index,control}/${user:0:1}/${user:0:2}/${user}/ ~/Maildir/;
  mv -v ~/Maildir/.INBOX/* ~/Maildir/;
  rmdir -v ~/Maildir/.INBOX;

Thanks again!
