            HI all. Shot in the dark here, but I was just wondering if there was a
    way to get sendmail to automatically block or discard any messages
    (preferably discard) any messages from a particular email address that are
    repeatedly rejected due to unresolvable domain names. About every day I'll
    get a spam message that has an invalid email addy on it that won't resolve,
    so when fetchmail tries to deliver it, it gets rejected and fetchmail
    doesn't delete it off the server. I'd like to eliminate that of
    possible. I would like sendmail to automatically just set that particular
    rejected email address to auto discard after 10 consecutive rejections for
    a period of 24 hours so that fetchmail doesn't allow a ton of mail to pile
    up on the remote server because the local sendmail instance is rejecting
    its delivery.

            If this is possible, let me know how to do it. Thanks.
