Huh?  This is a procmail script, not a shell script.  Get rid of this line.

So, the "headers.rc" file is at $HOME/Mail/rc.files/headers.rc"?
If the file is not at the right place, procmail will not post an
error, and keep right on going.

Two big problems here:

1. POST_ADDR_SPAN has no '$' to mark it as a variable, so it
   is matched as literal text.  Which fails.  Always.  Unless
   you get mail from "POST_ADDR_SPAN" :^)

   Also, you don't really need POST_ADDR_SPAN unless you wish to match
   something else after the address.  If the match is okay up to the
   beginning of $POST_ADDR_SPAN, then you are pretty certain of a good
   match--extra matching is superfluous.

2. You cannot continue an action without an escaped newline.  The recipe
   should read:

   :0
   * $$FROM(jdoe(_at_)nowhere(_dot_)com)
       | formail -A "X-Loop: $HERE" \
       | sendmail -oi $THERE

   Another way, though is:

   :0 fh
   * $$FROM(jdoe(_at_)nowhere(_dot_)com)
   | formail -A "X-Loop: $HERE"

   :0a
   ! -oi $THERE

I prefer the second method because:

* it is more efficient, since formail doesn't have to read the entire
  message;

* it is more portable, since it uses the pre-configured delivery agent, 
  $SENDMAIL $SENDMAILFLAGS, which may not always be sendmail.

G'luck.
