Question

我的程序大多数情况下工作正常。但是，有时我的SMTP服务器似乎关闭了连接或其他东西，程序似乎根本没有超时。

我在commons.mail上设置了以下参数：

SocketConnectionTimeout
了socketTimeout

但它没有按预期工作
当我的程序挂起时，请停留在此部分：

DEBUG: JavaMail version 1.4.4
DEBUG: successfully loaded resource: /META-INF/javamail.default.providers
DEBUG: Tables of loaded providers

我的发送电子邮件代码部分如下所示：

try {
    // Create the email message
    MultiPartEmail mpEmail = new MultiPartEmail();
    mpEmail.setDebug(true);
    mpEmail.setHostName(mail_relay_hostname);
    mpEmail.setSmtpPort(smtp_port);
    mpEmail.setSocketConnectionTimeout(socket_Connection_Timeout);
    mpEmail.setSocketTimeout(socket_Timeout);
    for (String toAddres : email.getTo()) {
        mpEmail.addTo(toAddres);
    }
    for (String ccAddres : email.getCc()) {
        mpEmail.addCc(ccAddres);
    }
    for (String bccAddres : email.getBcc()) {
        mpEmail.addBcc(bccAddres);
    }
    mpEmail.setFrom(email.getFrom());
    mpEmail.setSubject(email.getSubject());
    mpEmail.setMsg(email.getBody());
    if (email.hasAttachment()) {
        logger.info("Email has attachments.");
        int count = 1;
        for (File file : email.getAttachmentList()){
            // Create the attachment
            EmailAttachment attachment = new EmailAttachment();
            attachment.setPath(file.getAbsolutePath());
            attachment.setDisposition(EmailAttachment.ATTACHMENT);
            attachment.setDescription("Attachment"+count++);
            attachment.setName(file.getName());

            // add the attachment
            mpEmail.attach(attachment);
        }
    } else {
        logger.info("Email has not attachments.");
    }
    // send the email
    mpEmail.send();
} catch (EmailException ee) {
    // TODO: handle exception
    ee.printStackTrace();
}

欢迎任何提示。
提前谢谢。
