Can't set timeout on apache.commons.mail

Question

Can't set timeout on apache.commons.mail

My program works great most of the time. However, sometimes my SMTP servers seem to close the connection or something, and the program doesn't seem to time out at all.

I am configuring the following options on commons.mail:

SocketConnectionTimeout
SocketTimeout

But it doesn't work as expected.

When my program stays in this section:

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

My email sending code section looks like this:

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();
}
