/**
* transport is a simple program that creates a message, explicitly retrieves a
* Transport from the session based on the type of the address (it's
* InternetAddress, so SMTP will be used) and sends the message.
*
* usage: <code>java transport <i>"toaddr1[, toaddr2]*" from smtphost
* true|false</i></code><br>
* where <i>to</i> and <i>from</i> are the destination and origin email
* addresses, respectively, and <i>smtphost</i> is the hostname of the machine
* that has the smtp server running. The <i>to</i> addresses can be either a
* single email address or a comma-separated list of email addresses in quotes,
* i.e. "joe@machine, jane, max@server.com" The last parameter either turns on
* or turns off debugging during sending.
