    What is reject_naked_ip_address? I have never heard of this parameter
    (nor does it show up in postconf).

    At least one of the servers your message passed through has the IP
    address 216.89.240.184. If this is the address in question, then you can
    make a check_helo_access regexp or pcre table with line.

    /^\[?216\.89\.240\.184\]?$/ REJECT I don't think so

    Edit to taste,
    David
