We're currently languishing in the 19th century as far as email is concerned - RM Easymail as provided by the CC isn't the best way to do it in my opinion. I had originally planned to go down the Exchange route, but it seems like the costs will be too great, so I'm interested in an open source alternative.
I gather several people on here have had success with Zimbra, so i have some questions:
Is the free version sufficiently full-featured to use longterm? To put in perspective, our users currently log in to a webmail client everytime they want to access email, so Outlook integration isn't necessarily an expectation.
Is it possible, with the free version, to use IMAP for those users who might still want Outlook (or any other compatible email software). I've an idea that POP3 is possible, but i don't want email stores spread over every PC on site and not backed up..
Is AD integration possible for automatic account set up?
Any other advice? Alternative suggests? Shortcuts to make things easier? I've had some exposure to Ubuntu in the past, but don't want to make things more difficult for myself by using a GUI-less server edition of the OS - I'm presuming Zimbra will work alright on the normal desktop version?
Yes its full featured.
Yes you can use IMAP.
AD integration is possible for authentication and there's scripts available to bulk import your users as is.
I'd urge you to install the server version of Ubuntu instead of the Desktop as there are differences in the I/O functions etc.
Even if you install GUI onto the server version if you want to ...
Hope this helps.
Does that mean it will not work on desktop ubuntu? I am much more comfortable with the desktop version and have run all my other projects with it?
It will work, I just wouldn't advise it.
A bit like I wouldn't advise running server software on XP over 2003 if I could help it.
It is fully-featured for use - the only things you benefit if you pay is the support, Blackberry/push mail, hot backup etc.
We use exclusively the web client too to avoid nasty Outlook PST problems with profiles and so everyone is using the same interface (easier from support and training perspective). We use Mozilla Prism as a front-end client to the web interface because it's rendering engine is far superior and quicker than IE, gives the users of an "application" feel, can have popup notifications, and is separate from the machine's web browser. I developed a small C# launcher program for this too that makes use of Zimbra's pre-authentication functionality to provide seamless and passwordless logins on the network.
A GUI is an unnecessary overhead on a server - it's better to manage files via WinSCP or a console session via PuTTY and SSH.
You really don't need a GUI on the server to manage Zimbra... the admin controls are web based and you rarely need the console unless you are upgrading.
Webman's little gubbins all sound good too... if only he would share them with all us other 'geekers ;)
P.S. I'd use Debian over Ubuntu because I'm awkward :p
I decided to use Ubuntu because it had a 64bit version available to deal with my 16GB of RAM!
Thanks for the nod to prism, I'm just looking at it now and it looks very interesting.

Thanks for all the advice so far - looks like it should be pretty useful! A couple more queries - has anyone got a handy screen shot of the web interface, and how is performance on middling server hardware?
Get yourself a demo account and give it a whirl.
As for server specs, it's a tricky one, how many users are you looking at?
We've bought a dual quad core xeon with 16GB of ram for ours, 1250 users, probably 250 concurrent.
I dare say I overspecced?
All the screenies you could desire are at View demos of Zimbra enterprise messaging and collaboration software along with little videos :)
It really is dead easy to use.
We're a small school - so no more than 700 users, the majority of which are pupils and may well be happy with our up-coming VLE's email provision. Its really the staff who have the major issues with Easymail, so i'm guessing quite a modest server would do the trick.
Just a quick point - if you don't like using a command line, Webmin might be a useful alternative to a full GUI install. I haven't used it for some time, but I found it useful before I became confident enough to just use a command line.
