Please confirm my understanding here. In a text/plain message, BODY[TEXT] and BODY[1.TEXT] refer to the same data (the message body), and BODY[] and BODY[1] refer to the same data (the full message, header and body). But in a multipart/* message which contains a message/rfc822 part as its only part, BODY[TEXT] refers to the body of the outer multipart message - which is to say, the header and body of the inner message/rfc822 part together with the surrounding MIME boundaries and extra header - while BODY[1] refers to the encapsulated message/rfc822 part *without* the surrounding MIME boundaries or extra header, and BODY[1.TEXT] refers to only the body of the inner message/rfc822 part. Right?
Given a message with the following MIME structure, are these part specifier comments correct? ; beginning of [] ; beginning of [HEADER] Content-Type: multipart/mixed; boundary="a" ; end of [HEADER] ; beginning of [TEXT] --a ; beginning of [1.MIME] Content-Type: multipart/mixed; boundary="b" ; end of [1.MIME] ; beginning of [1] --b ; beginning of [1.1.MIME] Content-Type: text/plain ; end of [1.1.MIME] ; beginning of [1.1] lorem ipsum ; end of [1.1] --b-- ; end of [1] --a ; beginning of [2.MIME] Content-Type: message/rfc822 ; end of [2.MIME] ; beginning of [2] ; beginning of [2.HEADER] Content-Type: multipart/mixed; boundary="c" ; end of [2.HEADER] ; beginning of [2.TEXT] --c ; beginning of [2.1.MIME] Content-Type: text/plain ; end of [2.1.MIME] ; beginning of [2.1] lorem ipsum ; end of [2.1] --c-- ; end of [2.TEXT] ; end of [2] --a ; beginning of [3.MIME] Content-Type: message/rfc822 ; end of [3.MIME] ; beginning of [3] ; beginning of [3.HEADER] Content-Type: message/rfc822 ; end of [3.HEADER] ; beginning of [3.TEXT] Content-Type: multipart/mixed; boundary="d" ; no IMAP-specifiable part begins or ends here --d ; beginning of [3.1.MIME] Content-Type: text/plain ; end of [3.1.MIME] ; beginning of [3.1] lorem ipsum ; end of [3.1] --d-- ; end of [3.TEXT] ; end of [3] --a-- ; end of [TEXT] ; end of [] [3.TEXT], the body of a message/rfc822 part (contained within another message/rfc822 part), consists of a header and body, but IMAP provides no way to specify the header or body individually. With nested message/rfc822 parts, no extra specifier number is added, so we are only able to refer to the HEADER and TEXT of the outermost one. Only when a message/rfc822 part contains a multipart entity is an extra specifier number added, to refer to the parts contained in the multipart entity.
