Does Mail.app send or can request read receipts?
I was wondering whether Mail.app is able to send read receipts (or maybe it does silently?) or create emails that require those?
I know such a feature is available in Outlook.
I tested this using Mail on Snow Leopard connected to Exchange 2005.
There is no ability to set a request to receive read receipts.
Reading an email sent from Outlook in Windows to mail on Snow Leopard with a read recipt requested, does not send a read receipt.
Lion may vary.
