有很多應用都支持郵件的發送功能，比如ant。
使用普通的java application 發送郵件，需要java mail 庫http://java.sun.com/products/javamail/
和jaf庫http://java.sun.com/products/javamail/
基本代碼如下：
mport java.io.IOException;
import java.io.InputStream;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.SendFailedException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
/**
* use Java Mail API to send mails read configuration from mail.properties
*
* @author yiqian
*
*/
public class MailSender {
private final static String propertiesFileName = "mail.properties";
/**
* send the mail
*
* @param subject
* subject of the mail
* @param msgText
* content of the mail
*/
public static void send(String subject, String msgText) {
Properties props = loadProps();
Session session = Session.getInstance(props, null);
session.setDebug(false);
try {
// create a message
Message msg = new MimeMessage(session);
String mailList = props.getProperty("mail.to").trim();
// create to list
InternetAddress[] address = InternetAddress.parse(mailList);
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setSentDate(new Date());
// If the desired charset is known, you can use
// setText(text, charset)
msg.setText(msgText);
Transport transport = session.getTransport("smtp");
transport
.connect(props.getProperty("mail.smtp.host"), props
.getProperty("mail.user"), props
.getProperty("mail.passwd"));
transport.sendMessage(msg, msg
.getRecipients(Message.RecipientType.TO));
} catch (MessagingException mex) {
System.out.println("/n--Exception handling in msgsendsample.java");
mex.printStackTrace();
System.out.println();
Exception ex = mex;
do {
if (ex instanceof SendFailedException) {

Address[] invalid = sfex.getInvalidAddresses();
if (invalid != null) {
System.out.println(" ** Invalid Addresses");
if (invalid != null) {
for (int i = 0; i < invalid.length; i++)
System.out.println(" " + invalid[i]);
}
}
Address[] validUnsent = sfex.getValidUnsentAddresses();

}
}
}
System.out.println();
if (ex instanceof MessagingException)
ex = ((MessagingException) ex).getNextException();
else
ex = null;
} while (ex != null);
}
}
private static Properties loadProps() {
Properties props = new Properties();
InputStream in = null;
try {
in = MailSender.class.getResourceAsStream(propertiesFileName);
props.load(in);
props.load(in);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return props;
}
/**

*/
public static void main(String[] args) {
// TODO Auto-generated method stub
MailSender.send("test subject hot", "hello");
}
}
其配置文件mail.properties 如下
#SMTP server
mail.smtp.host=
#the user used to connect to SMTP server
mail.user=
mail.passwd=
mail.from=
mail.to=
