Hello 'email people'
RFC 2183 defines two basic disposition types, i.e. "inline" and "attachment".
But sometimes we need a more elaborate presentation than the existing
types. For example, the current advertisement way in Email or Webpage is very
"evil", sometimes it is difficult for the users to distinguish the real
from advertisement, and this is disgusting or confusing. Nowadays many email
service providers insert advertisements in the user's email. The inserted
advertisements normally are displayed at the end of the email, but sometimes
boundary between advertisements and other real contents is not clear. So that
the recipient may be misunderstanding, the advertisements might be regarded as
the real contents the sender writes.
However, advertisement is absolutely necessary for the development of internet
and mobile applications. In order not to interfere with users much, the
for sending advertisement kindly is needed. Email, MMS, IM and SIP messages may
use MIME as their content body, the advertisement could also be inserted into
the message body as a MIME content. Maybe a new disposition type can be defined
to help users distinguish the advertisement and the real contents. Its
is like this:
A bodypart should be marked "inline-subordinate" if it is intended to be
displayed automatically upon display of the message, but it should not block
other displayed bodyparts, e.g., bodyparts with a regular "inline" disposition
type. It is RECOMMENDED that the client render the content marked by
inline-subordinate in a separate place away from other inline contents.
