    Hello,

    Have you ever seen this error in your qmail-send logs?

    This can mean that someone you are trying to send e-mail to has violated the DNS protocol and is sending oversize DNS responses to your server.

    There are three solutions that can help with this problem.

    1. Install a djbdns DNS Resolver on your qmail server.
    2. Install the Big DNS patch for qmail.
    3. Ask the entity responding with oversize DNS results to fix their DNS.
