public final class Smtp

extends javax.swing.JDialog

implements java.awt.event.ActionListener, javax.swing.event.DocumentListener

A simple dialog for sending a SMTP mail. Mail sent from this dialog is not stored. The dialog send smtp mail, thats all. The dialog tries to be intelligent about sending mail. E.g. if a mail has been sent and the send button is pressed again without any changes in the fields, a warning appears. It will insert a signature file (~/.signature) if it exist, and try to guess the users from address. The to: and from: fields are required, and the message will not be sent if those fields are empty.

The class uses a SmtpAgent for the actual mail transport. The singelton pattern is used to have only one instance of this class in the JVM at anytime.
