Good day!
Dear habraly people, 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 sent message you need to have a confirmation of its delivery. There is one way in which 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, how to be here? Maybe someone came across this? Or have to be content only with non-delivery messages? How realistic is it to use a read request (after all, email clients ask whether to send it)?
