Are you absolutely sure that Trend isn't modifying the message at all?
Even if they're not stripping the attachment, or altering it, are they appending anything to the body of the message, or altering the subject line in any way?
I'm confused about the message tracking too. Are you saying that the message never arrives in the user's mailbox at all... or it arrives and then immediately disappears?
