Usage

From source file:SendMail.java

    try {/*from w ww.ja  v  a2  s.  c  o  m*/

        // Establish a network connection for sending mail

        c.connect(); // Connect to mail host
        PrintWriter out = // Get output stream to host

        // 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") + "@"

        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.

            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>]");
