Because I can find my 7 Celeron 400's a lot cheaper (or my old, free
P200's), to buy and replace, than your 4-way SMP Xeons (which I bet are
running an avg CPU load of under 5%).
Xeons are a hi-margin revenue solution for Intel and box makers, not a
productive product for me. My 7 boxes will have more total throughput,
greater total reliability and fail-over, and have lower TCO than your
XeonZilla's. (:-))))
And they'll fit in 7 2U rackmount cases and take up less space, too.

There's no necessity anywhere, it's a back-of-the-envelope type of
thing. But it's where I'm taking our shop.

yes, imo. What's a hop cost, really, on a switched, 100 megabit/sec
LAN? Come on, do you really sweat that sub-millisecond small stuff?
Another box is another point of failure, yes, but it's not an
all-your-eggs-in-one-basket point-of-failure.
I'll drop my egg. You drop your basket. (:-)))
or: "yours is bigger than mine" but mine satisfies better, lasts longer!!

Then, obviously, with no downstreams to route to, you don't do 2.5. But if
you had a dedicated list server at 4., you still need to split
cleaned/scanned traffic to Imail and list server.

It's robust and very serviceable for many list requirements, it's just not
"advanced".
