PEC Certified Mail

PEC certified e-mail is the e-mail messaging system that guarantees a certain confirmation with legal value of the delivery of the message to the recipient, it is comparable to the classic registered letter with return receipt.

All messages sent via PEC acquire a legal value in all cases provided for by law.
It guarantees the security of the message integrity, which cannot be altered in any way.

The sending and receiving of messages are certified by the “receipt” messages which are automatically forwarded to the sender when the message is sent and when the message is delivered.

The tracking system keeps the data for 30 months, allowing to verify and prove the sending of PEC messages in case of legal disputes.

Pursuant to Legislative Decree 185/2008, all companies and freelancers in business are obliged to file their certified e-mail address with the competent Chamber of Commerce.

All new companies are obliged to provide the PEC at the time of incorporation.

How PEC works

  1. The sender sends the message to the recipient through the authenticated and secure SMTP server via SSL
  2. The manager sends the sender a notification of acceptance or non-acceptance of the message, based on the checks carried out on the message. The receipt shows the date and time of sending, the subject of the message, information on the sender and recipient and any causes of non-acceptance.
  3. The message is then enveloped in a new message (called "transport envelope") digitally signed by the manager and sent to the recipient.
  4. The receiving manager checks the sending manager's signature and the validity of the message. In case of positive verification, it will send a receipt of acceptance.

Certify your domain

After activating the service, the provider / maintainer of the customer's domain will have to configure the DNS servers by pointing to the mx record indicated in the service activation email.
Maintaining the redirection over time is a necessary prerequisite for the correct functioning of the certified e-mail boxes. We certify the subdomain in the PEC system by publishing it in the DigitPA Index, as required by law.
