I'm at a customer site who's Exchange Server is being used as a "Relay Agent" by somebody.
In Exchange 5.5, if I use the "Specify By Host" option in the connections tab of the Internet Mail Service connector, can I enable a setting which will allow only the mail servers at the ISP to connect, and nobody else?
Also, the ISP (Demon) have many IP addresses for their email servers (a complete range), would the following entry be right?
194.217.242.1 255.255.255.0 Accept
0.0.0.0 0.0.0.0 Reject
Would this allow any email server in the 194.217.242 range to connect, and nothing else?
Any help is greatly appreciated.
