Yes, practically no difference in throughput, possibly even some loss in throughput due to spamc/spamd being invoked once per recipient, and amavisd invoking SA once per message. In other words, amavisd is just like spamd, but uses a different protocol to talk with MTA (a standard SMTP vs. a proprietary spamc protocol + unix pipe). Mark
