The Certified E-mail (PEC) is a specific kind of e-mail as legally valid as a registered mail with return receipt and it's generally used in the administrative and commercial fields.
When someone sends a PEC the provider responsible for its management will send the sender a receipt, containing the message delivery's date and hour as a proof of the operation. At the same time, the provider receiving the e-mail, after dropping it in the receiver's mailbox, will send the sender a receipt as proof of the reception, containing the operation's date and hour.
