Aye. So is the one I was mentioning. I keep trying to get it to do
more, but dan doesnt have any more mail to throw at it :-). It is totally
idle though. Yes that is also a problem with his site, a good chunk of the
mailings are to incorrect hotmeail.com, ecite.com, places :) And most of
the places have VERY slow front end mail servers like you noted. Wish
there was something one could do about that. But alas...

Below is what he was doing on a single ATA disk. Not even ATA100.
Thehn we transitioned him to a 3 x 9.1GB IBM Deathstar Vinum RAID-0
stripe for /var/spool/postfix/. Not to shabby for a single disk IDE
server. I was impressed. And yes these are for 24h. I don't have stats on
the SCSI array yet. Hopefully I can get those tonight. But the IDE disk
below was totally hammered. Between Postfix slamming the disks until there
was no I/O left and logging on the same drive, it was pretty ugly to watch
:-)
