Quota does not count physical useage, but the amount of bytes allocated by the messages. Maildir may hardlink messages, hence, they count multiple times for the quota, but once for du.
And in your case dovecot even compressed the mails: According to your doveconf, you are using mail_plugins = [...] zlib.
Dovecot's quota is calculated using the uncompressed size, whereas du shows you the space actually allocated.
