Preliminary information

Postecert , as you probably already know, is the Certified Electronic Mail service provided by Poste Italiane, one of the officially recognized PEC providers in Italy. This is an extremely useful and convenient service, as the e-mails sent and received on a PEC account have the same legal value as the registered letter with return receipt .

Its operation is completely similar to that of traditional electronic mail: the perception of use by the user, in fact, does not change at all, except for the fact that each message sent will correspond to the generation by the security systems of the provider of two notifications : one relating to the acceptance of the email by the manager and one for the delivery of the message to the recipient .

Registering with Postecert is also very simple to perform. The service allows you to take advantage of an e-mail box with a domain and a basic storage space of 100 MB (which can be extended up to 1 GB), guaranteeing security in sending electronic documents and attributing to them, as mentioned above, also legal value. Prices vary according to the duration of the subscription, with packages of € 5 + VAT for one year , € 9 + VAT for two years and € 10.50 + VAT for three years .

You should also know that the security levels implemented by Postecert follow very high standards: in particular, since August 2019 the communication protocols TLS 1.0 and TLS 1.1 have been discontinued, in line with the requirements of the Agency for Digital Italy for all. PEC managers, in order to increase security through the use of the TLS 1.2 protocol .

For you to know, TLS (Transport Layer Security) are advanced encryption protocols which, through special algorithms and the implementation of key exchange, authentication and data encryption methods, make telematic communications more secure.

If you are experiencing problems in using the PEC service in question, it is possible that the introduction of these additional security levels is at the origin, which is why it is essential to update the e-mail client . You may also need to check the IMAP parameters entered in your client. Furthermore, in many cases, any difficulties can also be overcome by performing a new account configuration, during which these settings are loaded automatically .

As regards in particular the parameters of incoming mail, I strongly suggest you use the IMAP protocol which, unlike the now outdated POP , keeps the messages downloaded from the client on remote servers, allowing the synchronization of all communications on multiple devices. . Below you will find the recommended settings for Postecert’s IMAP (incoming mail) and SMTP servers, to be used in your favorite client.


  • Server
  • IMAP protocol :
  • SSL / TSL security
  • Port 993


  • Server
  • SMTP protocol
  • SSL / TSL security
  • Port 465

If, however, you need to set up the POP protocol for incoming mail (which deletes messages from the server once downloaded from the client, so it is designed for use on only one device at a time), on the Postecert website you can find its parameters.
