> Try: postfwd or policyd rate limiting.

Sure! Thanks! A last question:

real situation: sasl+tls user accounts.

supposed situation: someone hack an account and take user+pass. That
person do a script like this:

i=0
while [ $i != 50 ]; do
echo test | /usr/bin/mail -s "test message$i" "vic...@domain1.org"
echo $i
i=$(( $i + 1 ))
done;

with anvil I can only slow down the spam:

anvil_rate_time_unit = 10s
anvil_status_update_time = 120s
smtpd_client_message_rate_limit=10

but if I modify the script that send an email spam every 5 minutes I can
by-pass anvil rules :-(

thanks for some advices

Pol
