Have the MX machine reject based on the envelope info, which will stop 90+% of the spam. You don't need a very powerful box as MX to do envelope rejection Then pass the remainder to a box much less powerful than you imagine for content-scanning. What volume of msgs do you have today? 100K? 500K msgs? here's the stats for yesterday: Grand Totals ------------ messages 186580 received 26185 delivered 0 forwarded 109 deferred (199 deferrals) 252 bounced 199942 rejected (88%) .... for an MX machine that is 330 MHz, 256 MB RAM, one ATA33 disk. %uptime 7:59AM up 35 days, 9:56, 1 user, load averages: 0.84, 0.36, 0.18 The .84 is due to a lot of hourly maillog scanning done by reporting programs in the last 10 minutes of the hour (ie, not mail relaying activity). The .18 is a more accurate indication of the load. So you can see that scanning 26k mgs received vs the 200K rejected is huge difference in volume, with a huge reduction in the requirements for expensive content-scanning. Note the 26K is really about 19K inbound and 7k outbound, meaning the content-scanning would only look at the 19K.
