That's quite a confusing paragraph. Do you just mean that "quota is
counted wrong for the old converted messages"?

How badly wrong is the quota? Show me some example values of what they
are and what they're supposed to be? How do you calculate what the quota
is supposed to be?

If all this is before the imap process is started, I don't see any
problems.

No.

Deleting maildirsize file recalculates the quota.

No.
