Not really. If someone tries to send messages too fast, they will in effect get throttled. Eg, if you set a policy of 10 messages/hour and they try to send 30 messages, then 20 of those will get deferred. After one hour, the user will have sent 10 messages and when the quota resets* for the next hour then another 10 will get through. And then the remaining 10 the next hour. The user has been throttled to 10 messages per hour which is effectively what the module is supposed to do. If they only send short bursts then their messages will get through at the rate you've throttled them to - but if they keep sending at a rate above the quota, their queue will just keep backing up more and more until messages start failing (max queue time exceeded). * Taking a simplistic view for illustration. If you want a laugh, or perhaps squirm, we have a customer that sends out mailshots on a regular basis. We keep trying to educate them, but some people just don't want to learn. What usually happens is that they send a mailshot and then phone us to complain that their internet connection is slow and remote users can't work properly. We thought we'd managed to educate them into keeping the emails small and linking to a web page for more info (they used to send out Word generated stuff !) - but this time they excelled themselves. An 8 1/2MByte messages sent to many thousands of recipients - and all sent individually rather than a smaller number of messages each to a number of recipients (it's how their software works). I estimated that this mailshot alone would fill their outbound connection for 4 1/2 days ! -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
