Debugging email is separate from debugging Java.
Are you sending one message to multiple recipients? (or by "personalised" do you mean that you have constructed 650 separate messages each with a single recipient?)
For the people who got 2 copies, are the copies identical? If so, are the "Received" and "Message-ID" headers also identical?
For the people who didn't get it (yet), are you getting bounced errors back to the envelope sender / return address mailbox?
