server listed as open relay, but not set up as one

[Jente]

Hi Everyone,

our mailserver is listed as an open relay, but I set it up to only relay from local IP's. anyhow, it is listed in ordb.org and njabl.org ... You will all surely understand I don't want that =).

Can someone provide good hyperlinks to make the server secure, or does someone wants to guide me on msn or such?

thanks for any help!

J.
