Redhat Linux下的JavaMail 问题！

[shuangsa]

用JavaMail 编了个发送邮件的小程序，
在windows下运行一切正常，邮件能发送成功，
但在linux下总发送不成功，错误提示：javax.mail.MessagingException: 500 Error: bad syntax

一、源程序

public class SendMail {
private static Log log = LogFactory.getLog(SendMail.class);
private static final String PROTOCOL = "mail.transport.protocol";
private static final String HOST = "mail.smtp.host";
private static final String PORT = "mail.smtp.port";
private static final String AUTH = "mail.smtp.auth";

public static void main(String[] args){
SendMail mail = new SendMail();
mail.sendMail("[e-mail]","hello!","Hello! this is a test.");
}

private String mailFile = "/mail.prop";
private Properties mailProps;
private boolean bAuth;

public SendMail(){
initSendProp();
}

private void initSendProp(){
try {
mailProps = new Properties();
mailProps.load(Utilities.getResourceAsStream(mailFile));
bAuth = mailProps.containsKey(AUTH) && Boolean.parseBoolean(mailProps.getProperty(AUTH));
log.info("init Mail prop!");
} catch (IOException e) {
log.error("init Mail error:"+e.getMessage());
e.printStackTrace();
}
}

private Properties getSessionProps(){
Properties props = new Properties();
props.put(PROTOCOL, mailProps.getProperty(PROTOCOL));
props.put(HOST, mailProps.getProperty(HOST));
props.put(PORT, mailProps.getProperty(PORT));
if (bAuth){
props.put(AUTH, "true");
}
return props;
}

private Session getMailSession(){
if (!bAuth){
return Session.getInstance(getSessionProps());
}else{
return Session.getInstance(getSessionProps(),
new Authenticator(){
public PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(mailProps.getProperty("username"),
mailProps.getProperty("password"));
}
}
);
}
}

public void sendMail(String to, String subject, String content){
try {
Message msg = new MimeMessage(getMailSession());
msg.setFrom(new InternetAddress(mailProps.getProperty("from")));
msg.setRecipient(Message.RecipientType.TO,
new InternetAddress(to));
msg.setSentDate(new Date());
msg.setSubject(subject);
msg.setText(content);
Transport.send(msg);
log.debug("Send mail to: "+to);
} catch (MessagingException e) {
e.printStackTrace();
log.error(e);
}
}
}

二、配置文件

mail.transport.protocol=smtp
mail.smtp.host=smtp.126.com
mail.smtp.port=25
mail.smtp.auth=true
username=***
password=111111
from=my<***@126.com>

windows 下一切正常
linux下出现如下异常：
javax.mail.MessagingException: 500 Error: bad syntax

好象是端口问题。。。

问题以解决:
在/etc/hosts文件中加入 127.0.0.1 myhostname
