Oh, believe me, I'm aware. This is why I'm subscribed from my personal email address now, instead of my work address. My work address no longer goes directly to a Unix inbox. It goes to a Microsoft one now. And technical mailing lists are just not acceptable in that environment. I'm still betting on "workplace transparent [as mud] HTTP proxy is causing unencrypted HTTP to fail" as the primary problem. Seeing the Outlook mangling just reinforces my diagnosis.
