Issues with Email delivery status

[horal]

Hi folks,
we are sending roughly 250K mails per day and experience troubles with getting delivery status.
It takes about 20 seconds to receive a delivery status per email. That's pretty long.
Is there a way to speed up receiving the email delivery status?
Thanks
