Curiously, yours was not colored by my mu4e viewer, whereas Joost's was.
The triple quotes notation originates from markdown (who may have
inherited it from another source, IDK).

Apparently specifying the language explicitly also helps to color your
code block.

    This is not colored:
```
;;; -*- lexical-binding: t -*-
;;
(defun foo ()
  (message "Bar"))
```

    But this is:
```emacs-lisp
;;; -*- lexical-binding: t -*-
;;
(defun foo ()
  (message "Bar"))
```

For other languages it's kind of hit-and-miss -- this only depends on
whether the mail client dev(s) feels like coloring these languages.
Mu4e doesn't color the following blocks, but maybe gnus would.

```c
int main(void) { return 1; }
```

```rust
fn main() { println!(); }
```
