Email Per domain limit not working.

Hello :)

Are you sure the messages are sending out immediately and not simply added to the mail queue for later delivery? The following option under the "Mail" tab in "WHM Home » Server Configuration » Tweak Settings" is important:

"The percentage of email messages (above the account’s hourly maximum) to queue and retry for delivery. (Minimum: 100; Maximum: 10,000)"

Per it's description:

When an account exceeds the maximum number of emails it is allowed to send per hour, by default, any additional messages are queued for delivery and sent in the next hour. This setting allows you to limit the number of messages that will be queued by the system. For example, if you set this value to 125%, once the account reaches its hourly limit, Exim will queue any additional messages, up to 125% of the Max hourly emails per domain value. Once the account reaches 125% of the Max hourly emails per domain value, any additional outgoing messages are discarded.

Thank you.
