We just call them in order case on the connection line. On two of the 4 SMTP gateways we use node 1 as the primary and node 2 as the secondary, on the other two, just the opposite. I know this is the poor mans way of doing this but we are lazy and haven't made our way to using something like LVS. > > > We are edging up to 95K a day now on only two machines.

So, we went with the two backend ends. It chocked. Then we kicked the -m from 30 to 6. 6 is a small number but it seems to be working fine. We have found for our environment that 6 to 8 works well. > > > We > > recently upgrade all of the hardware to Dell Dimension 4700's with 1.5gb > > ram each.

This is working great but will be readdressed during the next maintenance upgrade (which is about every 90 days). Gary
