Local Address
When you are sending messages among users in a LAN, the local address
is used in place of the extended network address. Local addressing is used
in a peripheral node or station and is transformed to or from an extended
address for delivery purposes. Often, within a LAN the domain is assumed
to be the local domain if no @domain is added to the address.
Mixed-Media Messaging
Messaging includes many options other than just text. Messages might
include all of the following types of information or any combination
thereof:
• Text - (includes word processing files, spreadsheets, database listing)
• Voice
• Fax
• Video
If you include more than one attachment or media type in your email
messages (such as graphics, video or sound), you must employ a method
called MIME (Multipurpose Internet/Mail Extensions). MIME is a
technique designed to bundle attachments within individual email
messages.
When a MIME file with attachments arrives at your workstation,
additional processing begins immediately. As the various attachments
arrive, the client or browser identifies these attachments by file type or by
description information in the attachment tag (as specified by the MIME
format). After the client or browser identifies a file, it can handle the file
playback or display. Sometimes the client or browser itself handles
playback or display (including .GIF and .JPG files).
When other kinds of files show up and need special handling capabilities
(beyond the scope of most client/browsers), the client hands off the files to
other Helper Applications for playback or display. Helper Applications
are designed to read and process the files and to present the file contents on
demand.
