Ubuntu server edition--Any MS exchange alternative?

Hi, I'm planning to set up a web server using Ubuntu server edition for a small organization and wanna setup email for them.

Just wonder if there's a good Microsoft Exchange alternative? So the members can check email using an email client while in office and web browser from wherever they are.

Thanks.

There are a ton of email programs like MS Exchange for linux. I just can't think of the name of the one I wanted to tell you.

Argh, I can't remember the name. But there is one out there. I think it's Evolution, not sure. I haven't used Linux in a while.

Bryce, I know there're quite a few MS Exchange for Linux out there, but they require Red Hat? I want one that is compatible with Ubuntu Server

Moreover, I'm a novice so I need some recommendations

Linux is Linux, if it runs on RH you can get it to run on Ubuntu.

Anyhow, this link should help.

Oh yeah, Evolution is an email client not a server.

Theak, what I need is more than just a server, I think.

The page you redirect me to is setting up an email server; it's just like having your own mail service instead of using Yahoo! Gmail etc...

What I need is something like an MS Exchange server; which I can check mails with Outlook on my computer, access my mailbox wherever I go...

What I say so far can be done with the scripts your URL introduced, but probably not the following.

What exactly I really want is that my Outloook (client) can SYNC to my server simultaneously.

eg If I made a reminder in Outlook (desktop) my other team members (if they're travelling) will know it by accessing our web server......

Zimbra is a good one as well as Open Exchange. Both have community versions.

Thanks. I've checked them out already. They're all good.. Probably I'll try them all out and compare
