Step #1: Tell your mail client to print out the ENTIRE header for the
 post that you receive, bounced back from the FFML.  Pine users just
 hit 'H' Netscape Mail users, go to View-Headers-All in the menu.
 People who use other mail clients should look up topic "Headers" in
 their help files. Mutt users already know what they are doing and
 don't need any help on my part.  (Sorry, FreeBSD doesn't quite have
 Eudora or Outlook (bwahahahahah!), so you're on your own.)

AOL users will find the complete headers at the bottom of the message
