Mail ignores read-receipt requests. If you receive mail in HTML format, the sender can embed image links that will inform him that you've opened the message. To prevent that, select Mail > Preferences > Viewing and uncheck the box labeled Display remote images in HTML messages. You can still load the images manually if you wish.

Linc, I need your help. I'm interested in 'the sender can embed image links that will inform him that you've opened the message'. Shall I start another post?

I have used my Online Web Access to my work Outlook account to send an e-mail to my Mac to be read by the Mac's Mail program. I've sent an HTML message with a request for a Read Recipt and a Delivery Receipt. Outlook got replies for both. I then sent a plaintext message and requested a Read Receipt and a Delivery Receipt. Outlook again got replies from both.
This started because a person that had emailed my wife said they receieved a read request. I told her that the Mac Mail program does not respond to those. We decided to test and I was shocked that I received the receipts. I then tested with my own Mac and was again shocked to receive both receipts.
My test used her work account and her .mac account. I then further tested using my .mac account as the recipient.
So while I believed as you said that the Mac Mail program does not respond to those, it clearly is.
Both Macs are running the latest operating system. My mac was just purchased last June.
Any ideas on how to stop the Mac Mail program from responding to Read Receipts and Delivery Receipts?
