- Choose add account → manual setup (or “other account”) in your mail app.
- Enter your full Poste Italiane PosteCert email address and password.
- Pick IMAP for incoming mail and enter the server, port and security from the table above.
- Enter the SMTP server for outgoing mail (mail.postecert.it, port 465) and enable authentication with the same login.
If the login keeps failing, check that IMAP/POP access is enabled in the Poste Italiane PosteCert web settings, and use an app password if your account uses two-step verification.
