Occassional our general manager has emails arrive where the last half of the email message body is missing.
if the sender re-sends, it arrives fine.
Exchange 2003, outlook 2000 at our end.
Exchange 2000/2003 and outlook 2000/2003 at the senders company.
Email is arriving by SMTP from the internet, passes through anti-spam servers and then hits our Head office server which the users mailbox is on. It does not route to another site so rule out internal connectors.
