This is the problem. Your MDA should enforce the quota usage. There's no
guarantees that Dovecot updates maildirsize after the Maildir has been
modified externally. Even when it updates it, it uses a different code
path ("quota recalculation"), which doesn't trigger quota warnings.

So use Dovecot's deliver and it'll do the quota enforcing and warnings.
