Thanks Amos!
I think I am going to go with Michael's suggested U60 w/2 450 MHz and 2 Gig memory. Or
U220r....
The E220R seems a bit excessive for us right now. I have 1000 users about 50 % imap.
I will slap external RAID for 80 gig space growth on it
I think I have to use the E220r for its intend purpose..sigh...
(How many production servers can one girl rebuild in a month?)
Thanks for the /usr/sbin/nscd -g from it I have:
98% passwd cache hit rate
50 % group cache hit rate
60 % hosts cache hit rate
What is ideal?
I really appreciate everyone's help.
This list is soooooo useful!

Oh gee, if you've got that, crack open the box. I would imagine
that would be sufficient, even if it only had one processor. You
just might need to get an external array for storage since this only
holds two disks.
kb> Memory and disks. What do you suggest for nscd settings?
kb> Using top
nscd? For your install base I'd be somewhat surprised that you'd
have to alter nscd all that much. You could raise the passwd entry
by some prime number. On our E250 looks like I've got:
suggested-size passwd 701
Just run this command periodically to see how you're doing:
/usr/sbin/nscd -g
If the hit rate isn't so swell, try bumping up the suggested-size.
Oh, on a more personally note, I've seen some spooky things with
some of the Solaris 7 patches, particularly the kernel and libthread
patches. While I know many folks are using this release, personally
I have a bit more faith with Solaris 8....
And I guess while I'm at it, my first inclination would be to move
Sendmail to a different host, then wire (reverse-pair) a direct
connection between the hosts. Both MTA work and Cyrus are heavy I/O
hogs and running them separately has worked well for us (though we
happen to be using Postfix, but all MTA are going to suck I/O.)
Hell, if you did that, you might even be able to get by with a Netra
T1 AC200 for the Sendmail host. Unlike the X1, this box uses SCSI
drives and has at least 1 PCI slot. The EDU price on this is pretty
reasonable.
Then again, your numbers indicated you were more CPU bound than I/O
bound, so maybe this would just be overkill.
