Oh, thank you, Mimestream, for letting me show an email with the light background for those three emails with diagrams with transparent backgrounds.

@kpl Oh, Mimestream. I had to point out to our security team recently: "y'know how you're always telling us to check the links in emails before clicking? y'know that Mimestream obfuscates everything so I can't actually check it, right?"

They were genuinely surprised at the realisation. (And no, they didn't fix it.)

@jamesog I thought they fixed that a while ago?
@kpl I just realised I'm thinking of Mime*cast*. Gah.
