Using javamail to send from hotmail?
private String mailhost = "smtp.live.com";

    public hotmailSenderActivity(String user, String password) {
    this.user = user;
    this.password = password;

  //This connects to the actual mailserver
    Security.addProvider(new com.provider.JSSEProvider());
    Properties props = new Properties();
    props.setProperty("mail.transport.protocol", "smtp");
    props.setProperty("mail.host", mailhost);
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "587");
    props.put("mail.smtp.socketFactory.port", "587");
    props.put("mail.smtp.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");
    props.put("smtp.starttls.enable", "true");
    props.put("mail.smtp.socketFactory.fallback", "false");
    props.setProperty("mail.smtp.quitwait", "false");

    session = Session.getDefaultInstance(props, this);

session.setDebug(true);

props.setProperty("mail.transport.protocol", "smtp");
    props.setProperty("mail.host", "smtp.live.com");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");

...
    props.put("mail.smtp.starttls.enable", "true");
    Session session = Session.getDefaultInstance(props);
    Transport trans = session.getTransport("smtp");
    trans.connect("smtp.live.com", 25, "user", "pass");
