msg.setRecipients(javax.mail.Message.RecipientType.To,address);//找不到符号
//只有javax.mail.Message.RecipientType 没有这个TO

老大，注意那个地方是TO不是To啊，那个单词是全部大写的，

我在我本机做了个测试，除了四楼说的问题外，应该还缺了用户名和密码校验。
我对java发邮件也不是很了解，提供一个程序作参考，不对的地方还请批正。

import java.util.Date;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SimpleMailSendMessage {
	public static void main(String[] args) {
		String host = "smtp.163.com";
		String to = "[e-mail]";
		String from = "[e-mail]";
		String subject = "javaMailTest";
		String messageText = "Hello ,java mail";
		boolean sessionDebug = false;

		Properties props = System.getProperties();
		props.put("mail.host", host);
		props.put("mail.smtp.port", 25);
		props.put("mail.transport.protocol", "smtp");
		props.put("mail.smtp.auth", "true");

		Session session = Session.getDefaultInstance(props,
				new Authenticator() {
					protected PasswordAuthentication getPasswordAuthentication()
					{
						return new PasswordAuthentication("[e-mail]","yourpassword");
					}
				});

		session.setDebug(sessionDebug);
		try {
			Message msg = new MimeMessage(session);
			msg.setFrom(new InternetAddress(from));
			InternetAddress[] address = { new InternetAddress(to) };
			msg.setRecipients(javax.mail.Message.RecipientType.TO, address);
			msg.setSubject(subject);
			msg.setSentDate(new Date());
			msg.setText(messageText);

			Transport.send(msg);
		} catch (Exception e) {
			e.printStackTrace();
		}

	}
