I was thinking the same thing. Heck, even Zonealarm or something just to
hold you over.

You can turn off unused/unwanted protocols under the Site, Configuration,
Protocols, properties for each protocol. This should render the ports
inactive and unable to accept connections on them. You can also do the same
on a per server basis under the Server, Protocols, properties for each
protocol. This will cover the Exchange protocols only though.
I really think that if you are wanting to filter that many ports, you should
look at a firewall. Heck, even if it is a software firewall to start with.
It would be better than nothing.

Thanks for the reply.
Not for relay, but we do not have any firewall as yet, and i would like to
close unecessary ports. Its a fresh installtion NT server PDC, Exchange 5.5.
So all the ports are open. I just want 25, 110, 80 to be open.
I tried that on TCP/IP security and nobody could connect to mail server ....

So are you saying someone used you as a relay or hacked your box or what?
Are you behind a FW? What ports are open to the Exch server?

Hello,
I have tried many times but failed to secure Our Exchange Server. We have a
Exchnage server for only
Server has NT4, IIS4, DNS.
How Do I use TCP IP security tab to configure security so that all the
unnecessary ports are closed, we only use exchnage for POP3 and SMTP.
The last time I tried I got Max user limit .... on SMTP
