Didn't know if you've seen this, but NYU School of Medicine uses Horde:

I have just rejoined the list at my new job. I missed the posts to
the lists for about a month or so. Here is a list of imp
installations that you might find to be interesting from my prior job:

Yes, these are really from the companies that they look like.

Btw, does this mean that Harvard, or part of it, is considering/adopting
IMP?
It does. We actually just rolled it out, and people have begun using it.
We're still working out a few kinks that are probably related to our
environment, such as the spellchecker and imp not communicating properly
(ispell works fine, and is the latest version; not sure what's up here).
Overall, we've had a lot of positive comments. The biggest complaints have
been related to its speed. There have also been a significant number of
requests for Eudora addressbook import options, which right now has no
straightforward solution (they have to be imported to outlook, then
imported from there to Imp).
The speed issue isn't too surprising. We have it running on four Compaq
tru64 boxes, which are also used for imap, pop, and shell logins for
thousands of users. If you'd like to know more about our environment, let
me know.
I'd imagine you would like to be able to mention this on your website,
which I admit would be pretty cool. Unfortunately, I'm not PR-authorized,
and cannot give you permission to mention this on your website, but I am
working closely with somebody who does have this authority, and while we
haven't discussed it specifically, I think we're on the same level in that
we are waiting until the major problems have been addressed. If he's not
thinking the same thoughts, I will mention to him that he should let you
guys make a plug for us on your site, once it's clear that we're sticking
with Imp (which right now is pretty certain, but not 100% certain).
Also btw, I live/work in Somerville, so if you need some consulting as
part of this, let me know. :)
That's good to know, thanks!

Hi,
We are a National Government Agency of Portugal and we are using Horde 2.0,
Imp 3.0 and Turba 1.0.
We have around 1.000 mailbox's, 8 Mail Servers (Exchange) and 1 Webmail
Server (Apache/SSL).
And you can add us to the list.

Subject: RE: [imp] Help Req. : Sizing a Horde\IMP system for 12,000 users
Speaking from experience combining Sun hardware/Cluster/and Imp/Horde:
I would first separate out your web server(s) from your mail and DB
server(s) especially if you plan on using a secure web server and/or
IMAPS. For this web server, use your best hardware, you may experience
high loads like we did using SSL, so you may also consider purchasing
crypto-cards if you run into this problem. The next (big) step would be
to run a scalable apache server (via Sun Cluster 3.0). This starts
getting pretty expensive, cost of licensing Sun Cluster 3.0 software,
the cost of agents, the cost of the approved architecture, and the cost
of support. Plus you definitely want to get some training if you're
going to run a Sun Cluster. (personally I wouldn't recommend this route
unless you really need HA and/or scalability.) I think option 2 from
Eric's message down below might be the sensible route in your situation.
Background:
We have been running Imp/Horde here at the University of Colorado since
the Summer of 2000 exclusively on Sun hardware. We initially opened it
up to existing students as an alternative option to pine/elm or
imaping/popping. The existing students had the choice to migrate over
from an older mail server to this WebMail system, and all new incoming
students were giving an account to this newer system. That first Fall
semester we started with 5000 user accounts, and today there are 40k. We
started off with (1)E3500 with 6 336MHz processors 2Gb of memory which
served as the mail (IMAP only) and mysql backend. The Front-end web
server was also a E3500 with 6 400MHz processors and 3 Gb of memory.
When we hit about 30k user accounts we started experiencing high load on
both servers. Granted, we do add some load with some in-house tweeks to
the IMP/Horde software for quota and affiliation check, as well as doing
secure IMAPS and SSL. We ended up with a soon to be 6 node V480 Sun
Cluster 3.0 system that is running scalable apache serving the front-end
(running IMP/Horde). For the backend, I ended up writing an agent for
both mysql and uw-imap and this is in a 2 node cluster running (2) V880
(one with 6 ultra-sparc-III 750MHz chips and the other with 8, one has
12 GB and the other has 16GB of memory). It's a screaming system now. I
have had my hands in this since the beginning, so if you want some more
info about what we are doing here and what we have learned, feel free to
contact me.
