      This is an SMTP *client* (smtp(8)) parameter, used to avoid repeated
      attempts to authenticated with an invalid password.

      This has no effect on the SMTP *server* (smtpd(8)) and Postfix does
      not cache SASL credentials. That would require mechanism-specific
      behaviour for which there is simply no code in Postfix.
