It looks like you're using sendmail, no?  Message ID's in sendmail will look
identical, except one character or so, when sent during the same SMTP session.
For example:


Jason A. Bertoch
Network Administrator
jason at electronet.net
Electronet Broadband Communications
3411 Capital Medical Blvd.
Tallahassee, FL 32308
(V) 850.222.0229 (F) 850.222.8771
