Well thanks all for the tips and pointing out what I was doing wrong here. I've decided to throw the whole thing out the window -- I'll be pulling the separate load balancer box out of the picture, moving the installation of Pound to the mail server itself, and just changing $EXTIP's hostname to be an alias for $MAILSERVER. Things will be much simpler, but not nearly as sexy. I suppose it'll do. :) Thanks again, John -- John Madden Sr. UNIX Systems Engineer Ivy Tech Community College of Indiana jmadden@ivytech.edu
