SMTP Connector Settings

Hello,

the SMTP connector (IIS 6.0) on IIS 7.5 is running fine. But I would like to throttle the email output on the server to maybe 200 Mails a day.

I checked the settings, where we have "Limit number of messages per connection to" (register Messages), but this does not throttle the number of messages at the same time.

I would rather like to have the message in the queue than to flood in case of uncontrolled emails other mails systems.

Any idea with Mircosoft settings?

Thanks
