I have a standard set up with not too much special, and have tried to send email with a delivery confirmation, and a read receipt, with a priority of high, and nothing ever comes back. No confirmation, nothing. I'm hesitant to ask for a flat out anwser, but would really appreciate any directions that you might be able to give me. Should it show somewhere in a server log? Which one? Is there a setting in postfix or the smpt / imap that needs to be set up to enable this? Thanks in advance.
