I meant to say thanks and that you gave me a good means for verification of authenticity for any e-mails that I might choose to send out in the future where "document origin" might be called into question. Kind of like a copyright I suppose. Maybe someone more versed in that area of expertise will come along and aid my ignorance.
Sending it to oneself in e-mail seems like a perfect means as one's own e-mail address would preceed any others and also establishes a timeline.
