An external e-mail was sent to 4 recipients at 1:46PM. The Exchange 2003 message tracker shows it arrived at the server at 1:46 and delivered to one recipient at 1:46. The message history header only shows one recipient. At 2:17 the same history screen shows another submission to advanced queueing and delivery to the other 3 mailboxes. The first recipient has a different domain name but it is all handled on the one server and the same mailstore. This is an SBS2003 system. A random check of other messages in the queue did not show up any similar issues. there are no issues in the system or application logs at this time.
