I *think* twisted.web.guard has this functionality... I've heard it's going
to be overhauled at some point, it's not as nice as it could be.

I'm even less of a twisted.mail expert than a twisted.web expert, but I
think that twisted.mail's auth stuff predates twisted.cred, and we haven't
had time to migrate it to twisted.cred yet.

Indeed. Our docs are slowly improving, but still quite lacking. If you or
anyone can contribute any, that would be great!

Hmm. That looks like a dubious change to me. Wouldn't that fail for
To: Mr. Example <dude at example.com>
I'm not familiar with smtp.py though...

1. Twisted doesn't require any C modules to be compiled -- they're basically
just optional speed-ups. In fact the only C module in Twisted that works
on Windows is cBanana; cReactor and portmap don't apply to Windows
because it doesn't have the relevant APIs.
2. I've heard it's possible to use the mingw port of gcc to compile python
extensions... search comp.lang.python or google for details.

Eek. The UI shouldn't crash, but regardless usually I use "runtests -t",
i.e. run in text mode.
Unfortunately Win32 support isn't 100% -- which tests are failing for you?
