That was the intent of what I was thinking
- something to tide him over. But he also didn't say whether
this was multihomed, or sitting in the DMZ (Gosh I hope not!), or what.
Without more specifics, we are trying to hit baseballs with straws.

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.

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?

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
