Mail Of Java

/*这个程序没有身份验证，
用户名，收件人都做死掉了，发的内容也是死的。
看明白了能否改进一下做个图形界面多点选择？

/*程序输出结果，你应该开心，逃掉了这么多细节

  取得缺省的session对象.
  如果当前没有session对象就新建一个对象作为缺省的sessoin
  缺省的session对象是共享的,在同一jvm中有效 .
  ，而session中又包含用户名，密码等敏感的东西，所以对这个对象访问是有限制的。
  创建session的能直接使用它。否则有更复杂的验证等着你。
.它假设javamail要的东西放在prop里。要求请看javaMail 规范的Appendix A
