I have two challenges in my Exchange 2007 environment.
1. I have a maximum recipents limit of 100. I need to be able to scale this down based on the file attachment size.
2. I need to be sure that messages to over 100 recipients are blocked, even if the message is sent multiple times to smaller user groups (ex. send the same message 3 times to 50 people -> the third message should be blocked). Can I do this in Exchange or do I need a third party tool?
The first issue is because we only have a T1 for email connectivity with about 500 users
The second issue is for US CAN SPAM ACT compliance, which defines a message as same subject line and content over a 24 hour window.
We are also using google's postini service for outbound delivery and inbound delivery.
Appreciate any suggestions you have.
