    After reinstalling ispconfig 3.2.1, I saw that a new certificate feature has entered. Coincidence or not, I'm in trouble sending and receiving email, with certificate error. And when accessing the Ispconfig panel Mozilla shows the error: SEC_ERROR_INADEQUATE_KEY_USAGE.

    do not know where to start, can someone help me?

    Try generarating a new cert for your hostname with the update script
    Code:
    ispconfig_update.sh --force

    Thanks for your reply, what do I do with the installed certificates? When ispconfig asks about self-signed certificates, create new certificates? The new installation option talks about let's encrypt, should I create for let's encrypt?

    Yes, create a new and let it generate a LE cert.

    After doing this, you might need to reconfigure services with the ISPConfig update script.
