New email system

No offense but I think that's a scare tactic sales consultants use to make money. It doesn't cost companies millions of dollars managing Linux servers over Microsoft systems because of hours / days it takes getting them working. Not that you're implying this directly but I hear so many people use this and it's beyond false. Any time spent managing a local mail server will be equal but mostly greater on a remote cloud system or any other environment. The point is there's the right tool for the right job and as long as you understand the limitations or your options, you can pick what's going to work best for you.

This is true.

In fact I have found myself spending months troubleshooting stupid exchange issues and never getting anywhere, especially with calendars, if it would be a linux based solution that is open source and well known, I could find way more info online and normally Linux issues turn out to be user error and it's a very simple fix. MS issues tend to be very convoluted and sometimes even MS themselves can't help. Once you get a Linux system running how you like, it will continue to run that way forever unless a change is introduced. MS stuff will just randomly have issues. One day everything can be like a field of roses, next day, random store corruption and errors left and right. This stuff does not happen with Linux, unless it's a hardware issue.
 
With the exception of hosting exchange (pain in the ass, not as a customer, but as the host) I have never had a problem with exchange I couldn't fix. As far as redundancy goes we run 2x SMTP servers that drop into our Spam servers which are in a microsoft active/passive failover cluster, that passes into an Exchange 2010 CAS array, with passes to 2x Exchange 2010 Mailbox servers running DAG for redundancy (basically Active/Passive clustering). This is all in a Microsoft Hyper-V failover cluster, so even if we lose a hypervisor everything migrates to the other server (servers are balanced between the two servers so that the environment never has a single point of failure).

To be honest, we have had no issues (other then things I missed in setup and corrected) and the overall setup was extremely easy.

I don't have an issue with open source stuff, however many times we are building environments that we are passing back to the local IT staff who have no *nix experience and thus we sell them microsoft because we need the local IT to be able to support it. Another problem are phones. Some of the nix email that I have played with has the ability to do outlook anywhere type functions, and can do push email to phones, however many times you have issues with blackberries (people gotta have their crackberries) and I don't know of a single open source server that is compatible with BES (yes I understand that you can just do a pop account, however how do you plan to sync contacts and calendar, and before you say you don't need that you have obviously never dealt with a blackberry user ).
 
We have been using Kerio (http://www.kerio.com/connect) for about 2 years in our production environment and it's as stable as can be.

It integrates with Active Directory easily and supports our 150+ user base easily, plus the cost is minimal compared to Exchange. Checking the server that it's running on currently: CentOS 5.4 configured in a VM on an iSCSI backend the load average for 5minutes bounces around 0.18 and 0.50 during peak hours.

The server itself has a current uptime of 197 days. I've had to bounce Kerio a couple of times to install new SSL certificates or install new major patches, but it has been a set and it forget it mailserver which is what I like. The initial configuration took some time getting kerberos to play nicely with Active Directory and things like that but nothing difficult.

My 2 cents.
 
Our company runs BOTH Exchange and Zimbra. The fact that our Exchange CALs got so expensive the more we grew, we needed a cheap alternative. I designed and implemented the Zimbra install here. On the free version alone, we're hosting 500+ mailboxes. The next version up which you have to pay a nominal fee for, gives you stuff like mailstore backup, etc.

Honestly, I couldn't be happier with how well Zimbra turned out. I did the install on Ubuntu 8.04LTS within a VMware ESXi 4 virtual machine and it installed relatively easily - and it's been up and running for well over six months now. The web administration interface is well laid out and easy to use and it has kept the higer-ups happy as well.

I'm also about to install a Zimbra server for another small company I consult for. I went over the pro's and con's with them about exchange vs zimbra and they have trialed both systems. So far they're liking Zimbra a lot.

If you're looking to save to money and have a good system in place, I would definitely recommend Zimbra.
