We are looking into migrating from Exchange to a much cheaper alternative.
We have approximately 1,200 users which will connect to the new server. These users will only need basic email access. They will connect up to the email server via pop3 without the need for any of the features in Exchange such as the Global Address list and such.
My question is, what are the best available options out there for our scenario? 1,200 users with the need for basic email access via pop3 using Outlook Express (preferrably.)
So far in the pot of software to test I have:
- OpenGroupware
- Scalix
- Zimbra
Any further recommendations, or expert opinions either the ones listed or other options??

You have mainly think about how your other infrastructure is setup aswell, MS vs Non-MS.
As MS - Exchange is well integrated with AD has its own advantages. Ex: If have all your desktops authenticating to the AD domain controler. The you would have to consider that aswell.
On the other hand, on Linux there are several (Groupwise well integrated with eDrectory, Citadel groupware suite)

oheil, thanks for the recommendations. I'll have to look into dovecot or cyrus mail system.
If we can stick with Windows based OS's, that would be ideal. We can get an SMTP server up and going, but did you have a recomendation for a pop3 solution for windows server based systems?
From what I can tell, it looks like dovecot and cyrus are Linux based.
If we have to go that route, we can. It will just be a much bigger and riskier transition since we are all unfamiliar with Linux.
askb, We are currently deciding what to do about that.
If need be we can completely segregate the new mail server for these remote locations and not incorporate it into active directory at all. This would also mean that we have to change their email addresses to a new domain or at least subdomain. That isn't ideal, however it is a possibility we are considering.
I'm just needing to get as much information about alternative options to Exchange as possible.
Thank you both very much for the help and information. Anything more is greatly appreciated.

What you basicaly need is the following (no costs at all):
SMTP: e.g. exim or postfix
POP3: e.g. dovecot or cyrus mail system
its open source I use (linux world). But at least exim runs also on windows using the cygwin environment.
When the OS could be linux I would recommend a debian lenny based system (easy install, easy administration, easy security updates).
