ocial network talk:

  - pretty useless; not any spam orientation at all

Joshua Goodman Received talk:

  - talking about parsing Received lines
  - basically reimplementing spamcop algorithm
  - looking for "last external IP address"
  - thinks this will be useful for SenderID
  - SenderID example uses HELO data, looks like, instead of
    PRA or SMTP MAIL FROM; due to multiple intervening hops

  - try to use heuristics to find last external IP address:
    - using MX data fails due to load-balancing edge router
    - also the msn.com/hotmail.com problem
  - proposed algo:
    - IP addr is 192.168
    - HELO matches user's domain and forward DNS lookup of
      HELO matches IP address
    - find an IP that matches MX record, next is external

  - Bob Atk suggested putting external IP addrs in a DNS record?!

Brett Watson: beyond identity: problems even with sender id

  - economics of whitelisting/blacklisting based on a reliable
    sender identification (ie. forging is no longer possible)

  - mostly a philsophical talk
