    It appears that when a batch of emails is passed to the Redhat Linux sendmail SMTP server, using JavaMail, the order in which the emails arrive at thedestination is not necessarily the same as the send order. Of course this can be due to the way the emails are processed at the receiving end, there could be multiple receiving servers at work. Or is the SMTP server know to send email out of sequence?

  2. Email doesn't have ordering guarantees between messages. If you need to
    process them in any particular order, you'll have to arrange that by
    some other means.

    It sounds as if you have control over that mail server. If so, just
    check its logs. It will have very detailed logs of all messages it
    accepted for delivery, and all messages that left it.
