BOF

SMTP+SPF: Killing Worms, Viruses, Joe-jobs, and Spam

Track: BOF
Date: Monday, July 07
Time: 7:00pm - 8:00pm
Location: Salon D

Fraud. Forgery. Worms. Viruses. Spam. These are all symptoms of a deeper problem: a security hole in SMTP itself. SPF closes the hole by inverting the blacklist concept: a legitimate domain publishes the IP addresses designated to send mail as that domain, and instructs SPF-aware MTAs to reject or suspect all other mail.

That allows people to better define who they do and don't want to get mail from, so blacklists can better operate based on sender domain, not IP address.

Naughty email usually forges the sender address of a reputable company. SPF easily protects legitimate domains from such forgery.

SPF support will be available for all major opensource MTAs by the end of 2003, and SPF data for the 100 largest ISPs and domains will be published in coming months.
