Read receipts in Entourage
After switching from Outlook to Entourage, I noticed that there is no option to request a read receipt on an email as Entourage doesn't support read receipts. The best work around is to create an email account excluded from send and receive that has the following header set on the Options tab of the account:
Header: Disposition-Notification-To
Value: Email address you want read receipt notifications sent to
