    This guy/gal we will call "The so-called idiot" has subscribed to the
    mailing list and turned his autoreply for his webmail on. So every
    time there is a posting to a certain list his email address autogens
    a response and sends it back out to the original sender of the mail.
    This is in turn something that mailing list software should protect
    against otherwise we could have a nice flood of webmail autoreply
    DoS's. I have added a procmail recipe to my $HOME/.procmailrc to
    delete these emailings along with other unwanted stuff from idiots
    like this one allready just to solve the problem until someone
    comes up with a great idea to add a "repeat mailing filter" (hint)
    to the mailing lists. Following is a procmailrc example for removing
    email from hosts that you dont want.

    # ---- Begin $HOME/.procmailrc ----

    SHELL=/bin/sh
    PATH=/bin:/usr/bin:/usr/local/bin
    MAILDIR=$HOME/mail
    DEFAULT=/var/mail/$LOGNAME
    LOGFILE=$HOME/log/procmail.log # Comment this out for no logs
    MAIL_ALLOW=$HOME/.procmail/mail.allow # List of allowed host patterns
    MAIL_DENY=$HOME/.procmail/mail.deny # List of denied host patterns

    :0:
    * ? formail -x"From" -x"From:" -x"Sender:" \
         -x"Reply-To:" -x"Return-Path:" -x"Received:" \
         | egrep -is -f $MAIL_DENY
    DROPBOX

    :0:
    * ? formail -x"From" -x"From:" -x"Sender:" \
         -x"Reply-To:" -x"Return-Path:" -x"Received:" \
         | egrep -is -f $MAIL_ALLOW
    ${DEFAULT}

    # ---- End of $HOME/.procmailrc ----

    Now just setup a couple of things. Make sure you have procmail
    installed. Create the $HOME/.procmailrc with the contents above.
    mkdir $HOME/log for log files. mkdir $HOME/.procmail for keeping
    the mail.allow and mail.deny filter files. Make sure to at least
    touch $HOME/.procmail/mail.allow & $HOME/.procmail/mail.deny.
    All done and set, you can start adding your host patterns to
    mail.deny or mail.allow in the form of any of the following.
    user@host.net, user@host, host.net, .host.net, @host.net,
    hostname.host.net. I would reccomend adding just single words
    to the deny file just for the reason of it will match if the
    word shows up anywhere in the fields that it greps and return
    true and ultimately dumping your mail to a DROPBOX. You can
    also change the DROPBOX part to a absolute path like "/dev/null"
    as well.

    Now just add the following to your $HOME/.forward file
    and youll have some easy filters setup for your control.

    "|IFS=' ' && exec /usr/local/bin/procmail -Yf- || exit 75 #USERNAME"

    ^^^ including the double quotes ^^^

    Best of luck.
