A Сложный пример составного сообщения
Приложение A. Сложный пример составного сообщения
Данное сообщение содержит пять частей, которые должны быть отображены последовательно: - два вводных объекта чистого текста, встроенное составное сообщение, объект типа text/enriched и завершающее инкапсулированное текстовое сообщение с символьным набором не ASCII типа. Встроенное составное сообщение в свою очередь содержит два объекта, которые должны отображаться в параллель, изображение и звуковой фрагмент.

Subject: A multipart example(составной пример)
Content-Type: multipart/mixed;boundary=unique-boundary-1
Это область преамбулы составного сообщения. Программы чтения почты, приспособленные для чтения составных сообщений, должны игнорировать эту преамбулу.
--unique-boundary-1
... Здесь размещается некоторый текст ...
[Заметим, что пробел между границей и началом текста в этой части означает, что не было никаких заголовков и данный текст представлен в символьном наборе US-ASCII.]
--unique-boundary-1
Content-type: text/plain; charset=US-ASCII
Это может быть частью предыдущей секции, но иллюстрирует различие непосредственного и неявного ввода текста частей тела.
--unique-boundary-1
Content-Type: multipart/parallel; boundary=unique-boundary-2
--unique-boundary-2
Content-Type: audio/basic
Content-Transfer-Encoding: base64
... здесь размещаются одноканальные аудио данные, полученные при частоте стробирования 8 кГц, представленные с использованием m-преобразования, и закодированные с привлечением base64 ...
--unique-boundary-2
Content-Type: image/jpeg
Content-Transfer-Encoding: base64
... здесь размещается изображение, закодированное с привлечением base64 ...
--unique-boundary-2--
--unique-boundary-1
Content-type: text/enriched
This is enriched.
как определено в RFC-1896
Isn't it
cool?
