how to configure for this? - 6.Aug.2008 10:54:02 AM

I want to block outbound (internet) emails from my exchange server for my users who send out multiple emails in a short time frame with the same subject/size.    I am being blacklisted for sending bulk or unsolicited emails.

I have configured my maximum recipients per message to 50 recipients.   Much less than that and I have problems with internal distribution groups.

Any ideas?    My hosted spam filter services say that I need to manage this at the Exchange level.

Thanks

If you're being blocked like that you've got other problems. Restricting quantity isn't going to help much. What are you sending? Sending a ton of mail now and again won't get you blacklisted unless you've got some shady content in there. I'd review the content before looking at restricting people.

I know this is my problem. I was using a hosted spam filter service and they shut me off. They gave me specific examples of why I was shut off. I had a few users sending unsolicited emails. They would send the same message to about 40 different recipients several times in about an hour time frame.

How I can systematically block this type of activity at the Exchange server level? I have spoken to MXLogic and Postini hosted spam filters, they both say to manage that at the Exchange server level.

So you had a bunch of users sending the same message 40 times to the same recipients. Exchange can't stop that for you.
You need either a behavioural solution (Mr two by four) or you need a decent contact management solution.
This has nothing to do with Exchange unfortunately. Postini are not correct. You cannot say that user X can only send 'n' number of messages to contact 'Z' per day.
