What the certified e-mail is

The certified electronic mail (P.E.C.) is a tool that allows you to give to an e-mail message the same legal value of a traditional signed mail with return receipt.
Both the sender's and the receiver's addresses have to be certified in order to have a certified e-mail.
For this reason, please use only certified accounts to send e-mails to our P.E.C.

The e-mail sent from not certified accounts will be rejected automatically.
