(template updated by RFC6533; previous version included in RFC5337) Type name: message Subtype name: global-disposition-notification Required parameters: none Optional parameters: none Encoding considerations: This media type contains disposition notification attributes in the UTF-8 charset. The 8-bit content transfer encoding MUST be used with this content-type, unless it is sent over a 7-bit transport environment, in which case quoted- printable or base64 may be necessary. Security considerations: See Section 7. Interoperability considerations: This media type provides functionality similar to the message/disposition-notification content-type for email message disposition information. Clients of the previous format will need to be upgraded to interpret the new format; however, the new media type makes it simple to identify the difference. Published specification: RFC 6533 Applications that use this media type: Email clients or servers that support message disposition notification generation or parsing. Additional information: Magic number(s): none File extension(s): The extension ".u8mdn" is suggested. Macintosh file type code(s): A uniform type identifier (UTI) of "public.utf8-email-message-disposition-notification" is suggested. This type conforms to "public.utf8-plain-text".
