I have a new method of dealing with mass mailings of junk mail.

I go to the InterNIC whois database and find the contact person for the
domain name being used and I return the mail to that person.  There may
be more than one contact listed.  In that case send it to all of them.

Then at the bottom of the information, you can find out who their feed is and 
look them up and send mail to them.

These people don't lke getting mail in their real personal E-Mail boxes.
This is a much better solution than sending to postmaster, root, or admin.

For MONEYWORLD.COM, send to willie@moneyworld.com and
willie@selfhelpnet.com.

Maybe I'll start forwarding other people's junk mail to them, or sign them
up for some junk mail mailing lists.
