    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. =/
