web项目中页面修改javamail发件人信息后发邮件失败

我们的web项目使用javamail发送邮件。页面可修改发送邮件的服务器、发件人信息,但是现在在页面修改发件人邮箱地址和密码之后,发送邮件失败。重起Tomcat服务器之后,又可以正常发送邮件,各位大神,有谁知道为什么呢?

public boolean sendMail(String subject, String body){  
    Properties props = new Properties();  
    props.put("mail.smtp.host", server);  
    props.put("mail.smtp.auth", needAuth);  
    props.put("mail.smtp.sender", sender);  
    props.put("mail.smtp.password", password);  

    // 判断是否需要身份认证  
    MailAuthenticator authenticator = null;  
    if (needAuth) {  
        authenticator = new MailAuthenticator(sender, password);  
    }  

    try {  
        Session session = Session.getDefaultInstance(props, authenticator);  
        MimeMessage message = new MimeMessage(session);  

        InternetAddress from = null;  
        if(null != sender && !"".equals(sender)){  
            from = new InternetAddress(sender);  
        }  

        message.setFrom(from);  
        String[] str = to.split(",");  
        InternetAddress[] address = new InternetAddress[str.length];   
        for (int i = 0; i < str.length; i++) {  
            address[i] = new InternetAddress(str[i]);  
        }  
        message.setRecipients(Message.RecipientType.TO,address);  

        message.setSubject(subject, "UTF-8");  
        message.setSentDate(new Date());  
        MimeBodyPart mbp = new MimeBodyPart();  
        mbp.setContent(body, "text/html;charset=UTF-8");  
        Multipart multipart = new MimeMultipart();  
        multipart.addBodyPart(mbp);  
        message.setContent(multipart);  
        Transport.send(message);  

        return true;  
    } catch (Exception e) {  
        return false;  
    }  

修改发件人之后,报如下异常:

com.sun.mail.smtp.SMTPSendFailedException: 550 Invalid User 684966a9-37c9-4b09-ba32-ea282cf46b58
;
nested exception is:

是不是tomcat缓存的问题
