public class MailSender {
	private MailSetting mSetting;

	private Session session;

	public MailSender(MailSetting mSetting) {
		this.mSetting = mSetting;

		final String username = mSetting.getUser();
		final String password = mSetting.getPassword();
		Properties props = new Properties();
		props.put("mail.smtp.host", mSetting.getSmtpHost());

			public PasswordAuthentication getPasswordAuthentication() {

	}

	public void sentMessage(String titile, String msg, String[] to)
			throws MessagingException {
		this.sentMessage(titile, msg, to, null);
	}

	public void sentMessage(String titile, String msg, String[] to, String[] cc)
			throws MessagingException {
		Message mailMessage = new MimeMessage(session);
		Address from = new InternetAddress(mSetting.getUser());
		mailMessage.setFrom(from);
		// Address to = new InternetAddress(mSetting.getUser());

		Address[] tos = new Address[to.length];
		for (int i = 0; i < to.length; i++) {
			tos[i] = new InternetAddress(to[i]);
		}
		mailMessage.setRecipients(Message.RecipientType.TO, tos);

		if (cc != null && cc.length > 0) {
			Address[] ccs = new Address[cc.length];
			for (int i = 0; i < cc.length; i++) {
				ccs[i] = new InternetAddress(cc[i]);
			}
			mailMessage.setRecipients(Message.RecipientType.CC, ccs);
		}

		mailMessage.setSubject(titile);
		mailMessage.setSentDate(new Date());
//		mailMessage.setText(msg);
		
		   BodyPart mdp = new MimeBodyPart(); 
		    mdp.setContent(msg, "text/html;charset=gb2312"); 
		    Multipart mm = new MimeMultipart(); 
		    mm.addBodyPart(mdp); 
		    mailMessage.setContent(mm); 
		    mailMessage.saveChanges(); 
		
		
		Transport.send(mailMessage);
	}
}

其中用到了一个MailSetting的类，其内容请参阅分享一个收邮件的类，使用相当简单

关于Javamail，几年间已经用了N多次了，其间也碰到了一些问题，也都一一解决了，比如发送附件，乱码等等，如果各位有兴趣就相关问题进行探讨，欢迎留言。
