 * msgmultisendsample creates a simple multipart/mixed message and sends it.

 * usage: <code>java msgmultisendsample <i>to from smtp true|false</i></code>

 * origin email addresses, respectively, and <i>smtp</i>
 * is the hostname of the machine that has smtp server
 * running.  The last parameter either turns on or turns off
