Yet Another Exchange Killer?
jmertic writes "SuSE Linux now has the latest Exchange killer, but this time for Exchange Server. Openexchange Server is designed to be a drop in replacement for Exchange 5.5 users who don't want to pay the MS tax of going to Exchange 2000. They say it will be available mid November."
I looked through the site, and could see no sign of native MAPI support - rather, you have the usual collection of IMAP, POP3, SMTP, etc. protocols. Many sites I look after would love to switch to a free Exchange replacement when they phase out their current 5.5 deployments - but if it doesn't support MAPI and seamlessly integrate with Outlook, they won't be interested.
It also seems to be missing a few of Exchange's better features: single instance message storage, (relatively) easy multi-site replication, deleted item retention, just to name a few.
Finally, who on Earth wants to put their Exchange server on their PDC? If this product doesn't integrate well with existing domains, I don't think that I have a single client who could actually use it!

This is being touted as an Exchange killer, yet it costs $1249 for 10 licenses?
I just looked up Exchange 2000 Server pricing. Assuming you're upgrading from Exchange 5.5, the base package for Exchange 2000 Server is $639 and the additional 5 licenses need to bring your server up to 10 licenses are $499, bringing your total to $1138.
You save $111 in license fees by upgrading to Exchange 2000 instead of buying this solution.
Here is where I got my prices for Exchange. Note that I have no affiliation with this company and have never bought software there; I found them on a Google search.
So, if cost isn't the advantage here, what is? Exchange 2000 is pretty much guaranteed to have more features and support. I can't see why anyone would want to buy this product.
Simpli - Your source for San Jose dedicated servers and colocation!
Didn't MS tax orginal aply to new computers which always came with a MS OS. even if you didn't want the OS, you still had to pay the license.
Admittedly, the "Integrated spam filter" and "DHCP" parts are not specified and might be closed source, but that seems quite unlikely, IMHO. Every other component seems to be both open sourced and free. Am I missing the reason you concluded it was closed-source?

Am I saying its no good? No; we haven't seen it yet. It's not an Exchange replacement. It looks like Bynari.
Bynari however, does produce an actual replacement for Exchange, especially when coupled with the InsightConnector for Outlook.
Also, the former HP OpenMail now owned by Samsung and called Samsung Contact appears to support MAPI as well, so that could integrate with Outlook and have all those groupware/calendaring features.
And last, a Dutch company called ConnecTUX has created a Linux-based server application called Team-Link that integrates completely with Outlook and mimics all Exchange features. (Both sites in Dutch unfortunately.)
So plenty of alternatives. But I agree, this OpenExchange, is not one of them.
I've run into this many times before with admins who come out of the MCSE mill. Unfortunately, there's no way to get your money back for Exchange/W2K once you've been ass reamed for it.
A good option that I've reccomended and implemented is phpGroupWare, which works really well for a small to medium size office that needs basic collaboration sofware.
The kroupware project and and is supposed to be exchange compatible as well as open source and free of those pesky licencing fees.
Scheduled completion by the end of the year.
Wow. SuSE doesn't have many supporters at /., eh?
I've used SuSE mail servers 2 and 3 at a few consulting clients and find them to be well designed, solid products. THe price on Version 2 was a paltry $399 or some such, but SuSE learned that people don't buy a good thing unless its expensive, so they ratcheted the price of v.3 to $999.
To install the SuSE server, you boot off the CD, accept all defaults and wait about 15 minutes. SuSE linux is installed jointly with the mail server, so from bare drive to fully functional takes about 20 minutes.
Previous versions work well with IMAP or POP (i use IMAP) and come bundled with a a custom version of Arkeia backup software so you can slap on a tape drive and back up the server every night.
Server has a great web mail client (much better in the Open Exchange version) and allows users to easily change their vacatin, auto-reply, forwarding prefs from a web config screen.
Using outlook, Mozilla, Netscape or any LDAP compliant email client, you can pull all your user addresses off the server with a link to the server based LDAP directory, no server based config needed.
I love this client for small business clients, and I will certainly give the latest a shot. Just 'cause the slashdot headline uses the term "exchange killer" doesn't mean you have to jump on SuSE like lemmings off a cliff.
SuSE often touts "exchange-like groupware" functionality, only to reveal that its soley available via the web based client scheduler. That aside, they make good products. If you don't have time to configure your own, its worth a shot.
with POP3 functionality.
Everything else will be "Planned for the future" and they will be recruiting programmers.
C'mon now! They even state on the features page that The preferred protocol is IMAP.
Why predict when you can read and find out?
Features page says it will come with SMTP, Webmail, IMAP, LDAP, spam filter, Samba PDC, and DHCP. The features include E-mail (of course), scheduler, document management, project management, addressbooks, forums, knowledgebase, etc., etc., etc..
Not that you can't piece these software packages yourself, but this sounds like it will be an integrated solution for mail server like Exchange or Groupwise servers, integrated IMAP and web interface; basically they want people to have OpenExchange server interoperate with MS Exchange server (migrating period), and after you're sure everything is set up correctly as you want it then ditch the MS Exchange completely. All this will be configurable through YaST too.
To me it sounds very nice as an alternative and way cheaper too.
Requiring marketshare ehh...
Boy you're making this hard...
Actually the first one I checked falls into this category... DELL... Maybe you've heard of them?
True you can get servers from them with RedHat now but near as I can tell anything in their Dimensions line (aimed at home users) gives you the generous choice of Win XP Home, Pro, Home with Plus or Pro with Plus. Their workstation line also gives you the choice of Win 2000. Oooo...
That's what people are complaining about with the MS tax business. See for your self, choose any desktop or workstation line and try to configure it without windows... you can't!
Ironically, it's those without the 'significant marketshare' who will sell you a computer without charging you for windows. Fred's house o' parts will probably happily assemble you a computer sans OS no problemo.
I detest MS Exchange for many reasons, but foremost because of MAPI. This package does not have MAPI specified, in which case it is correct of Telastyn to claim that it isn't a drop in replacement package.
MAPI is Outlook's native protocol which encapsulates calls to the Exchange server to retrieve/modify calendars, mailboxes and other objects.
This will probably be a nice mailserver-in-a-box deal and it's nice to see Linux vendors do these things. But to call it a drop in replacement sounds like a lot of hot air. PLEASE do not assume that I am in any way saying that Exchange is better. I am not. I am saying however, that vendors should take care in advertising more correctly. Otherwise they're proving to Exchange users that Exchange is the real deal and whatever is offered by SuSE is a joke.

Lotus Domino is far more powerful than Exchange. In features, security and performance. The new Notes 6 blows Outlook out of the water (as if R5 didn't already.)
open source != "free as in beer"
you can charge whatever you want for open source software, as long as you give the user the source code. since most large places with exchange servers list support as a requirement, the software wouldn't be complete if they just downloaded it. it may very well be that you're paying per seat for support.
You obviously didn't bother to read anything at the link provided. It offers a web interface, POP3 and IMAP (hence server-side storage), uses standard mailstores and OpenLDAP for the calandering and such. Recovery of mbox mailboxes is fairly trivial, however, I know nothing of recovering OpenLDAP (it seems to be Berkley DB so that should be possible). Accessing ex-employees info is simple, just reassign access to the OpenLDAP data and append the mbox to someone else. Heck, it's probably even an automated option in the web interface. As for mailbox recovery, if you delete a mbox, it's gone. That's why you have tape. I personally think it's stupid for Exchange to keep the data around after you delete someone. Talk about a long-term waste of space.

Who mods these things up? Exchange 5.0 can absolutely be secured not to relay mail. It has fewer relay options than Exchange 5.5 (or Exchange 2000), but it is absolutely configurable as relay secure. For those who need 'more' SMTP relay functionality than Exchange 5.0 supplies, there are a number of solutions which don't require upgrading the Exchange version to achieve.
While anyone posting as 'The Turd Report' is likely a troll, I'm sure there's at least one slashdot reader who is going to take what he said as gospel and repeat the misinformation elsewhere.
If you think this post is +1 informative, keep your karma mod the parent down instead.
Nah, Ximian Connector is just a kludge (a clever one), that uses Outlook Web Access (the web plugin to exchange) as a "behinds-the-scenes" proxy and via WebDav transfers stuff. I would think that it's performance would be greatly limited by this, plus it's limited to whatever OWA supports at any time. Any non-OWA exchange features wouldn't work
Not to be rude, but this is hilarious.
FIrst no mention of single instance storage. The money you save in licensing you'll spend in increased storage costs.
Please tell me you're joking. How much space do you think the average email server saves using this? At any rate Cyrus supports this, see http://winnie.acsu.buffalo.edu/doc/overview.html#s ingleinstance . Now I really wish people would stop bringing up that stupid buzzword.
Second where is the server based mail storage? Again the money you save on licensing you'll spend backing up mail downloaded on users' computers or home folders.
Thats a basic function of IMAP . You really should research this stuff.
Third, I didn't read anything about a web interface to read your mail like Outlook Web Access.
Ever heard of IMP or squirrellmail? http://www.squirrelmail.org/ How did you get moded +5??
Backups are the same scenario. Actually with Cyrus, you can simpley change the ACL on the mailbox to admin only if you want to prevent access and not delete it. Cyrus has it's entire admin functionality exposed as a PERL module so that you can script the server directly to do what the hell you want when a employee is terminated.
OpenLDAP is just as easy to back up. A simple LDIF dump, or copy the db files.
Both these packages are rock solid. I mean months and months with absolutely *zero* downtime, except for upgrades, and even then with failover the users never notices a thing. I've managed several. Including Cyrus in an ISP environment.
+5 ??!! LOL
Based on upvotes, Ageism is the only "-ism" Slashdotters care about and think isn't SJW
I don't understand what the fuzz is all about. Yast is not that great a tool that I would say everyone has to use it. The source code for Yast is there, and you are allowed to modify it as you wish -- with one condition: you have to label this version as a modified Yast-version. So no big deal! Try to focus on what SuSE has done for the OpenSource-community: They fund a lot of the ALSA-project development (Jaroslav Kysela), they heavily pushed the development of XFree86 including writing of drivers for until then unsupported cards, porting Linux to the s390 and much more. They also employ a couple of the KDE core developers (Waldo Bastian et al.).

SuSE is a European (German) company. They have done a lot of good work for Linux. Of course they are commercial. The recognize that to survive they need to sell.
Who cares that nobody in BC, Canada has heard of them? Maybe they do care themselves, they could be able to expand their market. I don't care, I have used their products for years.
Above the cost advantage, the following advantages are there:
- easy backup/restore: as everything is stored in IMAP folders (also contacts/calender info,...) individual mails or user accounts can be restored using normal filesystem backup/restore utilities. With Exchange everything is stored in 1 big black box file making it VERY, VERY hard to restore that email the CEO accidently deleted (you need to restore an entire Exchange server to another machine)
- high performance
- no per server user limit (I believe 2500 users is a hardcoded maximum in Exchange)
- runs not only on Intel hardware but also on PPC and Mainframe (interesting for big organisations)
- integrated antivirus software (Bynari ships with RAV)
- integrated Realtime Blacklist (www.mailabuse.org)
- Linux based (security, stability, performance, cost)
- Easy server clustering and replication with standard Linux tools (ultramonkey, rsync,...)
What isn't there yet: ;)
- integrated webmail (but you can do that quickly yourself)
- user authentication through Active Directory (will come)
- Security holes
If your computer has a PXE-enabled NIC you don't even need floppies to do your net-based install of Windows. It's called RIS. Still, most folks prefer to Ghost. But see here for a discussion of a voice-activated RIS-based install of Windows.
The restriction on YaST is that you cannot sell 'data carriers' containing the software. So for example you cannot sell CDs with a Linux distribution that contains YaST (SuSE Linux or otherwise). This seems a bit unreasonable from a company that makes its money selling CDs of software mostly written by others.
Still SuSE's policy is that patches to other programs are released under the same licence as the programs themselves, so they do good work in the rest of their distribution. But since YaST is a proprietary SuSE program, I can't really see the point in learning it (since it ties you to SuSE Linux and can never be used by the other distributions under the current licence). Better to support a distribution like Linux-Mandrake which makes sure its admin tools are released as free software.
YMMV, but at least you can appreciate the reasons why some users prefer to stay away from SuSE.
