[zhuq]

小弟求救于各位大虾，如何用java实现mail的传递，即收发mail

叩谢

你下在的jmail.zip里面不是又非常多的例子吗，一般的应用足够了

public static void send(final Mail sendMail) throws Exception {
final MailBox mailBox=sendMail.getMailFolder().getMailBox();
//发送邮件使用的服务器
String hostName = mailBox.getHostName();
//连接服务器的用户名
String userName = mailBox.getUserName();
//连接服务器的用户密码
String password = mailBox.getPassword();

//Properties env = System.getProperties();
Properties env=new Properties();
//存储发送邮件服务器的信息
env.put("mail.smtp.host", hostName);
//同时通过验证
env.put("mail.smtp.auth", "true");

//得到登陆器
AbstractAuthenticator authenticator = MailElementFactory.getInstance()
.createAuthenticator();
//根据属性新建一个邮件会话
Session session = Session.getDefaultInstance(env);
session.setDebug(false);

//创建一个消息
MimeMessage message = new MimeMessage(session);
//设定该消息的信息

//设定发件人
UserEMailAddress fromAddress = sendMail.getFromUser();
if (fromAddress != null) {
String fromUser = fromAddress.getUserName();
String fromEmail = fromAddress.getEmailAddress();
InternetAddress fromInter = new InternetAddress(fromUser, fromEmail);
message.setFrom(fromInter);
} else {
InternetAddress from=new InternetAddress("[e-mail]");
message.setFrom(from);
}

//设定发送到
Collection toUser = sendMail.getToUser();
if (toUser != null && toUser.size() > 0) {
Iterator iter = toUser.iterator();
while (iter.hasNext()) {
UserEMailAddress address = (UserEMailAddress) iter.next();
addAddress(message, address, Message.RecipientType.TO);
}
}

//设定抄送到
Collection copyUser = sendMail.getCopyUser();

Iterator iter = copyUser.iterator();
while (iter.hasNext()) {
UserEMailAddress address = (UserEMailAddress) iter.next();
addAddress(message, address, Message.RecipientType.CC);
}
}

//密送到
Collection copySecretUser = sendMail.getCopySecrecyUser();
if (copySecretUser != null && copySecretUser.size() > 0) {
Iterator iter = copySecretUser.iterator();
while (iter.hasNext()) {
UserEMailAddress address = (UserEMailAddress) iter.next();

//设定回复地址

.toArray(new Address[] {}));

//设定需要发送收条，第二参数为回复地址,可以多个设定
if(sendMail.isReplySign()){
//设定收条地址

}
message.addHeader("Disposition-Notification-To","[e-mail],[e-mail]");
}
}


//设定主题
message.setSubject(sendMail.getSubject());

//设定发送时间
message.setSentDate(sendMail.getSendDate());

//创建消息体

}

protected static void buildMessageContent(Message message,Mail sendMail)throws Exception {
// create and fill the first message part

//添加附件
