// File:  SendMail.java - A tiny application that sends an EMail message using SMTP

// A superior way to send (and receive) EMail is to use Sun's JavaMail support
// But, that is far more complex...  and requires downloading additional libraries
// So, for now, this tiny example should suffice

import sun.net.smtp.*;	// Note that sun.net.* packages are UNSUPPORTED
