POP Before SMTP

Already tried googling of course or I wouldnt have asked here, I'm not THAT
off  ;P   Most of the searches bring up close to the same information that I
was using previously which is to simply modify the sendmail.cf file with the
following information:

  # Add these lines to your ~/etc/sendmail.cf to implement the
POP-before-SMTP
  # anti-spam configuration.

  Krelayers hash /etc/relayers
  Kdequote dequote


############################################################################
#
  # Anti-Spam Support: Limit SMTP relaying to previously authenticated users
#

#
  Scheck_rcpt
  R< $+ @ $=w >        $@ OK
  R$+                  $: $(dequote "" $&{client_addr} $) $| $1
  R0 $| $*             $@ OK
  R$* $| $*            $: $(relayers $1 $: ERROR $)
  RERROR    $#error $@ 5.7.1 $: "550 SMTP relay denied, authenticate via
POP/IMAP first"
  R$*                  $@ OK

  This "used" to be the easiest method to setup and would automatically
enter your IP address into the relayers file and thereby allow you to send
mail but this does not appear to work with the newer version of sendmail so
I was wondering if anyone else had any ideas on a simple setup like this
since a Lot of the sendmail rules have changes since I last played with it
;P

I'm on Fbsd4.8 with the current Sendmail 8.12.8.   I havent used pop and
smtp on my server in 4 years now so none of my old information or
configurations work anymore. =/
