Already have 2 boxes for inbound. One of which is also doing outbound / ETRN. Also have a Postfix anti-virus box. >Postfix is HD IO bound.

Learned that the hard-way. >So you could start with two boxes that are cookie cutter replicas of each >other. Fast disk IO, decent processor, nice chunk of memory. Watch the >load. Then if this is not good enough performance get out the cookie cutter >again and stamp out another box of the same shape, size, etc. Already have done this. I will have 1 shot of doing this. I want to do this right, and be able to grow. Thus the questions on the list. I have been running Postfix for over 2 years. >You may find that 2 or 3 boxes does everything you need, and that would save >you the cost the 4th and possibly the 3rd box. Already have 3 boxes. >The way to get better IO has been gone over again and again.

What do you mean? >Redistribute non-Postfix IO. Dump logging off the box, How? Thanks Joel
