I have a server in the DMZ of my enterprise. It needs to be able to send email to my exchange 2000 server inside the firewall. Currently it can't. If I telnet on port 25, I get the response 220 ************************************************** I don't know what this means. It doesn't appear like it has telnetted through. The telnet session doesn't take any commands. does anyone know what this 220 message with a bunch of astericks mean? Thanks.
