Email compression

Email compression

Dear all,

        I don't know if this is the appropriate group to raise/discuss
this topic.  May be this topic somehow relates to internet technology.
Hope experts here give some pointers.

        Currently, user mailboxes are of limited sizes.  The content of
most emails are textual, thus higher compressable.  Even binary
attachments, say executables and bitmaps, are also readily compressed.
Is there any mail server/reader implementation pairs proceed to
compressing/decompressing the user mailboxes?

        There are several advantages:

        1. save disk storage
        2. save download time for users retrieving mail from their mailboxes
                (although modern modems perform some compression for us)
        3. reduce damage by mail bomb
                (e.g. a highly compressable mail bomb makes less damage)

        On the other hand, both server and reader have to perform more
task.  However, such task is supposed to be standard and simple.

        I think MIME can do some similar thing.  For example, use a
compressed content-type.  However, it has to deal with the hierarchical
content embedment problem.  In addition, some users do not use/like to
use MIME.

        This is just a rough idea.  Thanks for your attention.

1. Compression for Audio files

3.5MB sounds about right for one 3 1/2 min track.  The file will already be
compressed so zipping it will not make it any smaller.  The only way you'd
get it smaller is to encode the song with a lower rate e.g. normally for CD
quality youencode it using 128, try something smaller within the settings
like 96 or even smaller than that, of course the quality will drop.

If you want someone to receive the mp3, it's better to place it on a website
(likt Geocities or upload it to one of the
websites offering "virtual drive space" (like Yahoo! Briefcase that way, you can just send the URL to the
person and he/she can download it themselves.
