Please show how you do this. :) Please! :) For example, are you calling your AV backend with Postfix's content_filter setting? I'm not sure if/how it supports more than one host? Here is a simple one: content_filter = amavis:[123.456.7.8]:10024 How do you point it to more than one place? Then for SA, are you using spamc and spamd with -d and -H options to use DNS-based round robin load balancing? Is the spamc in something like a global maildrop filter? How are you doing these things? I presume you are not using weighted load balancing? > > We are edging up to 95K a day now on only two machines.

There were comments on another thread a day ago that dedicated boxes can handle that many children, but our experience is that SA hums along much better at around the default, even on a beefy dedicated box. > > > We > > > recently upgrade all of the hardware to Dell Dimension 4700's with > 1.5gb > > > ram each.
