Hi Orlando_Tech,<br />

Thanks for your detailed information. I checked, both default and client receivers are kept as default. Still, I can telnet port 25 locally on the exchange server, but not on other servers in LAN.

This is a newly setup MS Exchange 2010 server, on windows 2k8 r2 64bit system. After creating send connector, and set few other settings, and rebooting the server. All the exchange services are started, but if I tried to telnet, either locally on the server or remotely from other server in the network, I can't telnet port 25 successfully. Does this mean problem or some settings are not opened?<br />
<br />
Thanks in advance...

Why port 25 is not listening in Exchange 2010?

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
