SMTP Delivery Status Notification.
Good day!
Dear Habralyudi, I want to ask you for advice. There is a task in which it is necessary to send letters to various SMTP servers (not spam) and for each letter sent it is necessary to have a confirmation of its delivery. There is one way this can be achieved. It is called DSN (Delivery Status Notification) . But it is an SMTP extension and is not supported by many servers.
Therefore, I ask for advice on how to be here? Maybe someone came across this? Or will you have to settle for only bouncing messages? How realistic is it possible to use the request for reading (after all, email clients ask whether to send it)?
