Anti-spam WG RIPE 41 Amsterdam
Scribe Jeroen Bet, RIPE NCC to whom we are grateful.
About 40 people attended.
- Developments in UBE
- Open proxies -- leave no trace of origin in the mail.
- DNS hopping -- makes tracing almost impossible.
- Mainstream advertisers -- more, sometimes disappointed.
- Patterns of forged originators -- no major change.
- Developments in anti-spam
- Port filtering now deployed on many modem dialups. DSL not so good.
- MAPS RBL+ short of resources but respected. Other DNSBLs in chaos.
Can we support MAPS in some way?
(host a nameserver in Europe, encourage subscriptions).
- Regulation and legislation
- Californian legislation apparently effective.
- European legislation now to urge opt-IN.
- Child protection and UBE.
In the UK it is now accepted that mail abuse is unsolicited.
C Technical measures
- Filtering services; Brightmail, finding signatures fast.
Brightmail-like plugin for Sendmail if MAPS not sustainable?
- Various kinds of distributed blocklist.
- Sending mailer validation in real time.
- Other ISPs
- Mail provider trust model
- Bulk mailers
- Update RIPE-206 ( http://www.ripe.net/ripe/docs/spam.html )
- Make explicit comment on services supporting UBE.
- Opt-IN lists (work item)
- Start with LINX BCP http://www.linx.net/noncore/bcp/mailinglist-bcp.html
- Reporting UBE

- Privacy of the WG list.
- Statistics on paths of spam (for 80-20 attack).
