    As part of my periodic checks of things, I run a little script that has, in
    part ...

    echo "Checking our list of blacklists to be sure they still work..."
    baselist=`grep -v '^#' /etc/postfix/main.cf /etc/postfix/master.cf |\
              tr -d ',' | awk '/reject_rbl_client/ {print $NF}'`
    for BL in $baselist; do
            T="2.0.0.127.$BL"
            host "$T" || echo "host command failed on $T"
    done

    ... which lets me know if the RBLs I'm using are OK.

    -Shel

    PS: I'm sure that script can be improved upon, and it does depend on both
    postfix config files being one-command-per-line.

    PPS: I'm sure perl can do that with a single command, but my perl-fu is
    inadequate, and I am not worthy.
