/**
* A class to help send SMTP email.
* This class is an improvement on the sun.net.smtp.SmtpClient class
* found in the JDK. This version has extra functionality, and can be used
* with JVMs that did not extend from the JDK. It's not as robust as
* the JavaMail Standard Extension classes, but it's easier to use and
* easier to install, and has an Open Source license.
* <p>
* It can be used like this:
* </p>
* <pre>
* String mailhost = "localhost"; // or another mail host
* String from = "Mail Message Servlet <MailMessage@server.com>";
* String to = "to@you.com";
* String cc1 = "cc1@you.com";
* String cc2 = "cc2@you.com";
* String bcc = "bcc@you.com";
*
* MailMessage msg = new MailMessage(mailhost);
* msg.setPort(25);
* msg.from(from);
* msg.to(to);
* msg.cc(cc1);
* msg.cc(cc2);
* msg.bcc(bcc);
* msg.setSubject("Test subject");
* PrintStream out = msg.getPrintStream();
*
* Enumeration enum = req.getParameterNames();
* while (enum.hasMoreElements()) {
* String name = (String) enum.nextElement();
* String value = req.getParameter(name);
* out.println(name + " = " + value);
* }
*
* msg.sendAndClose();
* </pre>
* <p>
* Be sure to set the from address, then set the recipient
* addresses, then set the subject and other headers, then get the
* PrintStream, then write the message, and finally send and close.
* The class does minimal error checking internally; it counts on the mail
* host to complain if there's any malformatted input or out of order
* execution.
* </p>
* <p>
* An attachment mechanism based on RFC 1521 could be implemented on top of
* this class. In the meanwhile, JavaMail is the best solution for sending
* email with attachments.
* </p>
* <p>
* Still to do:
* </p>
* <ul>
* <li>Figure out how to close the connection in case of error</li>
* </ul>
*
* @version 1.1, 2000/03/19, added angle brackets to address, helps some servers
* version 1.0, 1999/12/29
