Hi All, is it possible to stop the SMTP queue when a certain amount of emails are in the queue, or when it hits a threshold per day etc. David

You can suspend the queue, you can see this link about more information:http://technet.microsoft.com/en-us/library/bb124034.aspx If you want to delete the mail in the queue, you can do like the link say.
