...but the times are very slow! for the same things of bogofilter, SA has taken 88 min! I think in this way I've not disabled each dns query, because I can't explain a so long processing time (and the CPU idle was > 80% of course).
You forgot dns_available no
SA will still do a DNS query to see if the From: address has a valid MX, even if RBLs are disabled. You can also disable rbls, dns checks, razor, dcc, pyzor etc by using the -L command line parameter.
