Add UTF-7 to the standard set of supported encoding converters. This is useful
when trying to pass Unicode data through transports that are only ASCII safe.

FULL PRODUCT VERSION :
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Classic VM (build 1.3.0, J2RE 1.3.0 IBM build co130-20020124 (JIT enabled: jitc)
)


FULL OPERATING SYSTEM VERSION :
The Operating System/2 Version is 4.50

A DESCRIPTION OF THE PROBLEM :
JavaMail should support all mail-specific charsets, such as
"unicode-1-1-utf-7" and perhaps others.

Hotmail.com, among others, frequently uses this encoding and
when JavaMail encounters it it results in the specified
error message (see below).

I have attached a testcase mail for you to parse below.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

JavaMail depends on the charset support in the JDK, so support for this
charset needs to be added to the JDK.
