Take a look. I have IMAP customers and the "Sent" folders are full. No maildirsize files in there.
I think they should all use the main .maildirsize.
With courier and sqwebmail all folders are included except "trash", unless you include it with "--with-trashquota" configure option.
On my courier IMAP, when I see the total quota for a single user, it's included of all folders.
About the rest, I agree totally with you.
