   Hi there.
   I would like to put some recognized certificates for the dovecot and postfix services.
   Would it be possible to change the self-generated certificates for validated certificates?
   
   If possible, how should I proceed to place it on my server?
   
   Greetings and thank you very much

   Run:
   
   ispconfig_update.sh --force
   
   and choose to regenerate the SSL cert during update. This will install a free Let's encrypt SSL certificate for postfix, dovecot, ISPConfig UI and pure-ftpd.
