Hello everyone,
I am having hard time with this one as I have tried everything possible that I know of but to no avail. I have a customer who have 20 thousand users on Exchange 2010. There is 8 MBX servers, 4 Hub transport and 4 CAS Servers.
The customer is complaining as some of their "Employees or Students" are using Telnet to send emails to one another using a different "Sender ID".
This works through the default connector "Default Servername" ..
I already told the customer to limit the servers that communicate with Exchange servers by placing IP range of the servers they have which count to hundreds of servers divided into multiple network Subnets.
So I am looking for a solution to allow the default connector to block all users on the network from sending emails using Telnet. Is this possible at all?
