Multipart MIME cheat sheet

• Best practices

I’ve had a couple of people ask me about MIME structure recently, especially how you create multipart messages, when you should use them and which variant of multipart you use for different things. (And I’m working on a MIME parser / generator for Abacus at the moment, so it’s all fresh in my mind)
So I’ve put together a quick cheat sheet, showing the structure of four common types of email, and how their MIME structure looks.
