SMTP: how to request confirmation?

[Raccoon29]

Hi everyone,

someone knows how to request for a mail read confirmation in an SMTP socket?
I think it might be a sort of flag or similars among the socket chars...

I mean, I've made an Smtp socket class, and I would like to allow the user to ask for a confirmation mail when the sent mail gets read. That is, the Outlook message: "The sender request for a confirm. Send the confirmation?"...or sort of.

I looked for it in whole Internet but noone talks about it, just Outlook checkboxes and smtp tutorials that doesn't talk about it.

Hope someone knows it,
really thanks in advance

PS: @admins, I was in doubt between "General programming" and "General discuss"... I hope that I did the right choice

You set a "Disposition-Notification-To: <address@where.to.send.the.notification.to>" header in the email.

Great, exactly what I was looking for!
