Yes, it probably is. Proxad.net is not where he normally sends e-mail
from. He contributes to other W3C mailing lists. We haven't blocked
him from any other lists for that reason.

But while we are waiting for technology to detect forgeries, I have
blocked him from www-style only, since has wasn't subscribed to that
list anyway.

We're experimenting with SPF (now called Sender-ID, I believe), which
may help a bit to counter forgeries. I encourage everybody who
operates an SMTP server to add an SPF field to the DNS record for that
server. See http://spf.pobox.com/ (If this is gibberish to you, ignore
it, you're almost certainly not operating an SMTP server. Just make
sure your virus and firewall software is up to date.)
