You could also search the documentation.

According to that same documentation that I referred to a while
ago, you can exclude clients from all smtpd_client_xxx limits:

smtpd_client_event_limit_exceptions (default: $mynetworks)
   Clients that are excluded from connection count, connection rate, or
   SMTP request rate restrictions. See the mynetworks parameter descrip-
   tion for the parameter value syntax.

mynetworks (default: see postconf -d output)
   ...
   Specify a list of [...] Specify "!pattern" to exclude an
   address or network block from the list.

So you need something like:

    smtpd_client_event_limit_exceptions = !1.2.3.4/5 static:all
