Jon, Does this work for you? I was trying to get it up and running, didn't work, so I added a few debugging printf's and noticed that it looks up Domain: 0.0.2.151.relays.orbs.org For each message no matter what's in the "Received" line.. I also wanted to say thanks for starting the development on this.. I was looking for something like this! -j ----- Original Message ----- From: "Jon Rust" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, November 02, 2000 1:08 PM Subject: ANNOUNCE: qrblcheck -- rbl checking for .qmail > I took rblcheck and added some extra code to read a message from stdin, > find the IP of the last relay.
