How to limit the number of emails sent per unit of time in Exchange 2003?

Question

Microsoft Exchange

The question is this: there are users who make large mailings, and since the domain has already been on the DNSBL black list once, I want to take all precautions so that the situation does not repeat itself. How to limit the number of emails sent per user per time unit in Exchange 2003? Thanks in advance for your reply. Google did not give a clear answer.

Answer 1

There is no such setting in Exchange - "limit the number of emails sent per minute/hour/day". However, you can limit the number of maximum connections to say 4 and limit the number of messages sent per connection to 4
