Mail::Field#initialize

Create a field by name and optional value:

 Mail::Field.new("field-name", "value")
 # => #<Mail::Field …>

Values that aren't strings or arrays are coerced to Strings with `#to_s`.

 Mail::Field.new("field-name", 1234)
 # => #<Mail::Field …>

 Mail::Field.new('content-type', ['text', 'plain', {:charset => 'UTF-8'}])
 # => #<Mail::Field …>
