|
|
Mailing
List
|
A
typically automated system that allows people to
send Email to one address, whereupon their
message is copied and sent to all of the other

MIME
|
Multipurpose
Internet Mail Extensions -
The standard for attaching non-text files to
standard Internet mail messages. These files
include: graphics, sound files, spreadsheets,
formatted word-processor documents,etc.An email
program is said to be MIME Compliant if it can
both send and receive files using the MIME
standard.Generally speaking the MIME standard is
a way of specifying both the type of file being
sent (e.g. a Quicktime video file), and
the method that should be used to turn it back
into its original form. Web servers use this
method to identify the files they are sending to
clients so that formatting will be done
appopriately. Web browsers typically list pairs
of MIME-Types in a table so that you can control
what software will be used to handle each
type.

which other users can interact with in their
