I'm hoping that spam filters will detect the inconsistent header information
and not blacklist me at cdel(_at_)firsthand(_dot_)net but I'm not hopeful.
In fact, there isn't any sane way to detect "inconsistent" header information
without external hints - this is the reason why there's the SPF proposal, the
Yahoo domain-keys proposal, and Microsoft's proposal. (Contemplate
the headers on this piece of e-mail for a nonce, and ask yourself if they're
consistent or not. Then consider the fact that I've on at least one occasion
posted to this list from this same laptop, but at the time I was behind a
NAT'ed firewall in California....)
