Usage

From source file:SendMail.java

public static void main(String[] args) {
    try {/*  ww w.  j a  v  a  2  s . com*/
        // If the user specified a mailhost, tell the system about it.
        if (args.length >= 1)

        // A Reader stream to read from the console
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

        // Ask the user for the from, to, and subject lines
        System.out.print("From: ");
        String from = in.readLine();
        System.out.print("To: ");
        String to = in.readLine();
        System.out.print("Subject: ");
        String subject = in.readLine();

        // Establish a network connection for sending mail
        URL u = new URL("mailto:" + to); // Create a mailto: URL
        URLConnection c = u.openConnection(); // Create its URLConnection
        c.setDoInput(false); // Specify no input from it
        c.setDoOutput(true); // Specify we'll do output
        System.out.println("Connecting..."); // Tell the user
        System.out.flush(); // Tell them right now
        c.connect(); // Connect to mail host
        PrintWriter out = // Get output stream to host
                new PrintWriter(new OutputStreamWriter(c.getOutputStream()));

        // We're talking to the SMTP server now.
        // Write out mail headers. Don't let users fake the From address
        out.print("From: \"" + from + "\" <" + System.getProperty("user.name") + "@"
                + InetAddress.getLocalHost().getHostName() + ">\r\n");
        out.print("To: " + to + "\r\n");
        out.print("Subject: " + subject + "\r\n");
        out.print("\r\n"); // blank line to end the list of headers

        // Now ask the user to enter the body of the message
        System.out.println("Enter the message. " + "End with a '.' on a line by itself.");
        // Read message line by line and send it out.
        String line;
        for (;;) {
            line = in.readLine();
            if ((line == null) || line.equals("."))
                break;
            out.print(line + "\r\n");
        }

        // Close (and flush) the stream to terminate the message
        out.close();
        // Tell the user it was successfully sent.
        System.out.println("Message sent.");
    } catch (Exception e) { // Handle any exceptions, print error message.
        System.err.println(e);
        System.err.println("Usage: java SendMail [<mailhost>]");
