failure to parse recipient value when the name is an e-mail address containing additional quotes

Found in production, an e-mail has the 'from' field with the following value:
```ex
""[email protected]" " <[email protected]>
````

which is incorrectly parsed into `[email protected]\"` instead of
```ex
{"\"[email protected]\"", "[email protected]"}
````
