WHM / cPanel - Maximum hourly emails notification limit reach for one account

Job ID: 33111487

Budget: $10 – $15 USD

We have one client on our VPS server (WHM/cPanel). They need to use a larger amount of emails. We set it to 2000 per hour.
We changed the tweak settings and as well in the profile. Nothing changed. The user still has a limit of 500 per hour.
We need someone who can asap resolve this issue. They got mail delivery after they send 500 emails.
