Changes: SPF checks are no longer performed by sending a query out to a central server. The extension does all of the SPF work itself. However, email messages with DomainKeys info are still checked the old way when SPF fails. There are also new rudimentary checks for "domain look-alikes".

In the last two years, the extension was rewritten to do SPF queries on its own, without contacting my web server, and DomainKeys checks are turned off by default, so the privacy concerns have been addressed.

Yeah, but I challenge you to write a portable extension that does everything in JavaScript. Way difficult, and maybe not even possible. Plus, I posted the source code for the HTTP server script on the site, so if you're concerned about privacy, you're free to set up your own private system.
Everything in life is a tradeoff. In this case, phishing protection versus total privacy.
Why does this use HTTP instead of DNS?
This extension causes your thunderbird to send details about every email you open to a CGI on taubz.for.net.
Can't it be written to cause Thunderbird to use DNS directly instead?
I'm a bit worried about the privacy issues there...
Other than that - it seems pretty keen :-)
