Open Source Microsoft Exchange Alternative

Were currently running Exchange 2003 and are considering upgrading hopefully to something open source and was wondering whats out there that has Exchange-like features like activesync and web-mail

I was just looking at OpenChange and it looks like a pretty cool project

For the record, that does not sound like a project that will end well (IMHO).

Zimbra would be my vote if you absolutely had to get away from Exchange but you are not going to find anything better than the newer versions of Exchange.

Thanks to you both, I plan to compare the features and bring up what i find during my next IT meeting

Dont forget to consider backup and disaster recovery. There are proven solutions for Exchange from Microsoft, Symantec, Commvault, and others. Sometimes you are paying not just for features, but insurance.

SP1 for 2010 made it even more sweet. I am about to put a couple of new drives in a server so I can put peoples' mail archives in a separate information store, I am almost giddy.

- Having said that I couldn't disagree more with the recommendation. I have seen Zimbra bring orgs to there collective knees with downtime. There is another time honored email server out there that a small portion of users love and swear by: GroupWise!

Zimbra works pretty well. The thing I didn't like was the paid versions. You paid per seat, which is okay. Then you paid more for archiving, etc.

My last company at my behest went with Kerio. It's not open source but works on Windows, Linux, and Macintosh servers. The price per user was very affordable.

I can pm you the contact for a few school district in Utah that use it if you want to hear from the horses mouth.
