Good morning, I request a plugin that when sending the mail, I see it in thunderbird on my computer when it was received and the time, thank you.
It cannot be done. Thunderbird - like any standard email program - does not know when or whether your message was received.
You can request a Delivery Status Notification, or a Return Receipt but you cannot guarantee getting either - it depends on the recipient.
