Returns the default value of the field requested as a symbol.

Each header field has a :default method which returns the most common use case for that field, for example, the date field types will return a DateTime object when sent :default, the subject, or unstructured fields will return a decoded string of their value, the address field types will return a single addr_spec or an array of addr_specs if there is more than one.
