Body Content Type

Depending upon the kind of message being sent, this information is either appended to the header or included in the body of a multipart-alternative message. The appropriate header for this content type will be used, overriding the appended header in List Info. Note that ListManager will insert its own boundaries in multipart-alternative messages. Each message body, text or HTML, will have its own Body Content Type field.

The default value(s) are safe for messages which don't use extended characters. For messages with extended character sets or other encoding, please see International Character Sets.
