1. Software for managing AD: not really that expensive. On Linux you need to spend as much to write and maintain custom scripts, Webforms and what not.
2. Backup software: yes, because Exchange has its internal database format (i.e. it does not use only flat files). You can't back that up without suspending I/O to a consistent state which means you have to have an application-side plugin.
3. LVM: can't create crash-consistent snapshots of database files so what you say is incorrect, unless you meant snapshots of ordinary IMAP directories (incorrect comparison - database format vs. flat files). Besides, if you have VSS H/W Provider agent on Exchange server, you can take snapshots (on storage or the server itself), re-mount them and backup them using the regular Windows software.

Re:Incorrect assumptions (Score:4, Interesting)
A huge number of people that got stuck with Exchange servers want to get rid of them. That's why these articles keep coming up.
What you meant was that you need the address book and directory services. Scheduling tends to be done by secretaries, and forms/IMAP folder sharing is generally not needed. Now if you say you *want* scheduling, etc, then fine, there are a number of quality products from which you can choose. If you define "what you need" to be the exact feature set of Exchange, then it isn't surprising that you think you need it. You can implement everything that Exchange/Outlook does with other software, cheaper, with more reliability, and on less hardware.
1. As for AD management software... let's see. You bought Windows Server because it's easy to use and admin, Exchange because it's easy to admin, and are using AD because it's easy to admin. So to do it right, you have to buy third party software? Sounds more like somebody screwed up their research and choose a bad solution based on broken assumptions. You have to do basically the same thing on any platform, so that's not a good reason to choose one over another. The UNIX solutions are much more reliable than Exchange, too, and less expensive. They also provide all the same functionality. Unless you go out of your way to ignore the solutions that work, anyway.
2. That's because Windows' does not provide functionality such as LVM. An application can also lock a file and prevent any app with any access level from even reading it. Exchange also keeps quite a lot open and locked when it doesn't need to. If the app was written well, it wouldn't be a problem. However, your backup explaination is an excellent example of why Windows is a huge pain in the ass.
3. BS, that is a perfectly valid comparison; backing up email is backing up email. If the application is written properly, the database will be fine. Exchange isn't written well, so it has problems. That software doesn't even provide a way to do a backup without either getting third party software or shutting Exchange down. Also, your VSS stuff is essentially the *exact same thing* as LVM snapshots. Why would your way work when LVM wouldn't? If the database is inconsistent, then it's inconsistent either way.
So what you're saying is that Windows/Exchange is better because it requires more jumping through hoops, buying more random software, and more dealing with random BS like bad data formats and bad storage techniques?

In a small (but growing) business of a dozen employees, an old NT server SBS edition with Exchange 5.5 needed to be replaced. I decided to go with a Linux server.
On the Exchange side, what I didn't like was:
1. all email is in a proprietary database, in a single (huge!) file. If something goes wrong with that file (as it once did), it's a nightmare to bring it back up, if it works at all. If you can't repair it, you loose anything that came in after the last backup.
2. speaking of backups, Exchange needs special Exchange-aware backup programs. You cannot just copy the files.
3. Lack of flexibility in handling of incoming mail, spam filtering, forwarding, etc.
4. No ssh access for quick and easy remote administration.
5. No simple text-file based configuration, meaning no grep or such to find some setting. You have to move around all the menus if you cannot remember where a setting was.
6. It is hard to move away from proprietary solutions like Exchange because you cannot just copy files and hand them over to another application. That's a good reason to do it rather sooner than later when it may become harder yet. It was not easy to move mailboxes from Exchange to IMAP.
So in the new setup, I used Postfix and Courier IMAP:
1. very easy and very flexible and powerful configuration
2. all configuration through simple text files which can be grep-ed, compared, backed-up, whatever.
3. simple backups through plain file copies or rsync
4. every mail is in it's own plain text file. Can be grep-ed, and if a file goes corrupt (didn't happen yet), it is only that single email.
5. easy administration. For example, I didn't implement quotas, but I'm considering setting up a little script that would check for the size of the maildirs and of single huge files, and send a little email to the users. Like "you are using up 1 GB for emails; please consider removing unnecessary stuff" or "Would you please check if you still need the 50 10 MB files in you mailbox". I can easily add a summary of the huge mails so the user knows which ones they are.
5. easy migration. If I ever decide I would like to replace Postfix or Courier with some other program, it's no problem. I'm not locked in the current programs. Not that I would want to move to other programs. I'm very happy with this setup. But I like to be sure I can if I ever wish to.
This has been running reliably for 6 months now, and I'm a very happy mail admin.

After?
Outlook 2003, alas!
The upgrade from Office 97 with Outlook 2000 to Office/Outlook 2003 was not easy. So during a few days, they used Thunderbird for email. Easy to set up, always works, leaves mails on the server (the way I set it up), no hassles.
But most users wanted Outlook. Only 2 still use Thunderbird. Probably my fault: I didn't do any training for Thunderbird. So I suspect that apart from the mushy Fisher-Price TB icons, their problem with TB was mainly that they thought they couldn't do some things because they didn't look in the menus. Nobody was able to give me rational reasons why they preferred Outlook. Anyway, I believe users should have the freedom to use what they like.
Aside from the autoresponder, were there other features that didn't work anymore?
There is no shared calendar, but nobody was using that anyway. If they do want that some day, I don't know what I could use for that and it may be a problem.
There is no central Exchange address book, but that was not needed. They have their own database with all the business contacts, including emails. If needed later, I can set up an LDAP solution or whatever.
Aside from the administrative benefits, were there other features that piggybacked their way in and were found to be useful?
- Free and excellent antivirus (ClamAV)
- Free and excellent spam filtering (a couple of RBLs, header checks in Postfix, and Spamassassin to mark the remaining spam as such)
- Remote administration through SSH. That is not only an admin benefit, but also a user benefit. With Exchange, if they had a problem/question/requirement, they had to wait for me to come by. Now, I can act immediately over SSH. (Of course, you can setup VNC to manage a GUI, but it is slow and clunky). There are also answers I can give them straight away by looking at the logs (X says he didn't get my email / Yes he did; mail.x.com accepted the mail at 12h32; he should ask his own mail admin. I didn't get the email from Y / True, it was rejected because it was 20 MB. etc.)
What safeguards to do you have in place to ensure that those emails are protected from prying eyes?
Nothing special. There is no particular need. There are no "prying eyes" inside the network, and they do regularly have their mail read by someone else to whom they give their password (it's not a bug, it's a feature).
There is no WiFi on the network. I try to explain to them they should use better passwords anyway, but most don't care.
As an admin, I can of course read everything if I want. But I don't want to, and more importantly, they have to fully trust their network admin. If they don't, they need to find another admin quickly anyway. In this regard, network admins are like bookkeepers and doctors. You cannot have one whom you don't trust.

SMTP is whatever you want, but Postfix is what they recommend. I've tried practically every Exchange replacement out there (SLES/SLOX, OpenExchange, a plethora of web-based crap, Bynari, Steltor (now Oracle's) CorporateTime, Hitachi's solution, etc., etc.) and this one is the (clear) winner in my eyes. The entire thing is written in Python, including the Outlook connector, and everything but the connector is open-source. (Outlook connectors are EUR$50/seat with discounts for volume). We still run Outlook on the desktops since that is the user interface and many here still want it, but as far as the backend is concerned, I couldn't be happier now. There is something just plain cool about being able to run arbitrary SQL queries over all of the company's emails, contacts, todos, journals, you name it... We have it tying in to our Asterisk [asterisk.org] PBX as well so, for example, the service guy who's on call gets the emergency page. The service department just maintains their Pager Calendar and I do a lookup to see who's on duty.
E4L isn't without its warts (the IMAP server is still in early development, no POP or LDAP yet), but being Open Source and also being in active development, these get polished or cut out (as necessary) in time. And I can add/change the system and get my changes contributed back. I don't have to worry about where my data went to or if the system ever crashes how to recover the data. If some weird-ass situation comes up and I need to correlate my data in some unforseen way... well now I can, and I don't need some kind of screwed-up and possibly commercial API to get it done. And most importantly for me, I don't have to worry about the system changing or being eliminated due to some other company's paradigm shift.

If you actually look at the details, it's a Linux based (Red Hat RPM distro at the moment) that appears to be the absolute best web email system I've seen to date. AJAX is only a very small part of what Zimbra does. AJAX simply improves the end user browser experience by making it feel more like a local application and less like a web app. AJAX allows for page updates without reloading the whole page so it can add features like drag and drop, right-clicking context menus, live searches, etc. i.e. faster instant feedback much more like a native app.
The person behind the site is the former CTO of BEA Systems (WebLogic). He wanted a better email system that was available anywhere. Grouping of discussion threads, saved searches (like Mac OS Tiger), etc. What this group has come up with is pretty darn interesting and if it's well designed will only get better.
The geek reading Slashdot ought to go read the Admin Guide available from Downloads_Documentation_Admin Guide (PDF or HTML). There are some real nice technical explanations not found in the marketing flash demo!
Before you continue to bash it, go check out the technical details while keeping in mind that it's new and will be improved as time moves forward. Linux, Apache Tomcat, PostFix, MySQL, OpenLDAP, SMTP, LMTP, SOAP, XML, IMAP, POP, and AJAX. You can connect with IMAP and POP clients! This means you might be able to connect via IMAP with OS X Mail.app which supports much of the threading, sorting and search features not found in Outlook. iCal can use the calendar system. Addressbook can connect to the LDAP directory for GAL entries. Pretty darn slick! Zimbra has certainly gotten my attention. If you have to you could use Outlook, but I would rather use the web interface then use Outlook! Ugh...
Should be interesting if someone decides to do the same thing in Ruby On Rails! Might be easier to build and maintain and thus faster to market with new features. Same technology except substituting Java and Tomcat for Ruby, the Rails API, plus Lighttpd & FCGI. Go take a look at Basecamp, Backpack, and Ta-da List and you can see that http://www.37signals.com/ [37signals.com] could easily build a similar system to Zimbra and make it sing! Or course the 37signals way of things is to host it for you and you subscribe to it. Zimbra is meant to be installed by your geeks with a support contract to Zimbra and consulting available. There also TextDrive's Strongspace Ruby on Rails app http://strongspace.com/ [strongspace.com]. There is going to be an explosion of such applications being refreshed by AJAX powered feedback. AJAX is exciting as it can greatly improve the user experience. But that's all it does, the backend geekness is where the real fun begins. Whether it's Java or RoR things are going to start changing. Get ready for Web 2.0 without the Web 1.0 hype and dotbomb! You must have a viable business model to succeed with Web 2.0!
