// Get system properties

// Properties props = System. getProperties (); this is the case in many examples. In fact, the following sentence is better and can be used in the applet.

Properties props = new Properties ();

// Setup mail server

Props. put ("mail. smtp. host", host );

Props. put ("mail. smtp. auth", "true "); //

// Get session

Session session = Session. getDefaultInstance (props );

// Watch the mail commands go by to the mail server

Session. setDebug (true );

// Define message

MimeMessage message = new MimeMessage (session );

Message. setFrom (new InternetAddress (from ));

Message. addRecipient (Message. RecipientType.,
