Hi,

I am looking for an internal email server that will support 100 users,
it will need a good functional web-client and will store message data
or message header data in MS-SQL. We are not looking for an Outlook
solution (we wish to purely have a web-client interface for our
users). Preferably not an Exchange Solution either (cost).

What I am trying to do is as follows:
We have a web based CRM system that we have built in Cold-Fusion, what
we want is for our users to nominate to store emails (outgoing and
incoming). These will then be flagged or moved and stored. Our CRM
package already has our customers email addresses, so we can just
create a simple query page that will pull up a summary of sent and
received emails, complete with date-time, subject, sender, reciever,
for that particular client. I do not need any calendaring or any other
groupware.

We have looked at a couple of solutions and this has been our results:

IMS Fusionmail - Fantastic SQL storage, but really basic webclient (we
would have to do a lot of development bringing it up to par)
@MAil - Fantastic package all round, but uses MySQL only and we would
have to get header logging as a mod (although cheap to do)
Merak Icewarp - Awesome looking server, but only stores account and
domain details in SQL and no mail information.
Open-Exchange free version - looks perfect, but had two seperate
people try to get it to work without success (too bleeding edge still)
Open-Exchange Suse version - looks perfect, but ridiculously expensive
(more so than Mr. Gates it appears) and comes with a lot of
calendaring and groupware that I don't need.

I hope there is something out there (surely we are not the only
company that needs to store and centrally reference emails)?

Thanking you,
Marc
