Configuring my Exchange 5.5 server

[NogginBoink]

Well, I discovered yesterday that the spammers found my Exchange server sitting naked on the Internet. (Took 'em long enough, honestly.)

So now I need to clamp down the settings. I need to be able to send mail from my user account (using Outlook) from home and the office, to any mail recipient, but only allow others to use my SMTP server to send to local recipients.

I am a self-admitted Exchange moron. Furthermore, I have absolutely no desire to learn Exchange. My Exchange server maintenance consists of rebooting the server when mail stops flowing, and that's *it*.

Can anyone offer the correct settings?

Don't really know Exchange 5.5, but you'll want to lock down open relay and authenticate only users sending mail that are in your domain/IP subnet.

Put a post in Networking forum. I know there's some 5.5 guys over there.
