Entourage email program help please ?

I have Microsoft Office for Mac installed so I use the Entourage email program. I am wanting to make it so I can automatically request a receipt of the emails I send to clients. I have looked but I can not find the feature that allows me to request a receipt. Is it possible I missed it or does it simply not exist in Entourage? Thanks

Although I'm not sure how much use it will be, here's the skinny on read receipts in Entourage:

Return Receipt

Just keep in mind that read receipts are not a standard part of the POP3 email protocol. Many people are used to using Outlook with an Exchange server in a corporate environment. And in that setting, read receipts can be quite useful since the administrator can enforce their usage. However, there is no facility for them on POP3 servers.
