email parsing

[ra9ftm]

It is my first script on python. Don't know is it correctly uses
modules, but it is working fine with specially with russian code pages
and mime formated messages. Also quoted-printable and base64
encoded....

It will be very good if anybody post any comments on this script. Is
it good or bad...
