In a Microsoft Exchange Server 2007 environment, you send an e-mail message by using an IMAP4 client together with the APPEND command. Additionally, you do not set the \Seen flag in the APPEND command. In this case, the delivery time of the e-mail message is stamped with the current date and time instead of the date and time that was passed by the APPEND command.
Note The following Knowledge Base article fixes a similar problem if you do set the \Seen flag in the APPEND command.
