Can We Finally Ditch Exchange?
from the another-one-for-the-FAQ-list dept.
"With new releases on the way, like Mandrake 9.0 and the new Lycoris can we who try to use Free Software in business environments hope for any change? Do the commercial Linux distros have any plans to implement a free replacement for Exchange, including a Win32 client-side bridge? If not, why not? Do you feel it is too cost prohibitive to imitate Bynari in this case, or is it a decision more along the lines of 'we'd rather you used Evolution and Mandrake/Lycoris/Whatever, rather than OutLook and Win32'? If it's the latter I'd be severely disappointed, and I don't think I'm alone. Any discussion on this topic would be appreciated; but what I'd really love is a community push to get this done. Perhaps a running Web-A-Thon to raise the money to simply purchase the technology from Bynari? I personally think it would be a great move towards grabbing market share from some of the other distributions, some of which have the technology but choose to keep it closed, as well as from the Great Dragon.

The reason for this is simple. Exchange uses the Outlook client; the Outlook client comes with Office; Office is the de-facto standard software for almost any corporation that uses computers.
At first I thought if there was an open source system that was compatible with Outlook that would do the trick, however HP offered a system that did just that, and even it didn't make a dent in Exchange's market.

Two things...
First, HP's product (now owned aparently by Samsung) wasn't really open source, although it did run on some open source platforms. It was certainly not free software.
Second, HP never really made much of an effort to try to sell their product. It sure looked like they were afraid of reprisals from Microsoft if it was too successful.
So I don't think we really know for sure what would happen if there were a free/open source calendar/messaging/groupware server that was compatible with Outlook clients... I personally think it would become quite popular, especially with small to mid sized businesses that would like to save some money in today's trying financial climate.

However, there are two issues with it that bother the hell out of me: (Note: This is Exchange 5.5, not the latest one. Nobody where I work is interested in paying gobs more when there's free stuff out there.)
1.) The copy we have is limited to 25 licenses. This means that 25 connections are allowed at one time. More than that and Exchange punts you. "Sorry, you have to wait until a connection is open."
The IMAP protocol is particularly attractive, so it's used a lot. But it counts as 2 connections because it makes one for inbound and one for outbound. So you can have 12.5 simultaneous connections before Exchange says "Sorry, give me more money."
What makes it worse is that IMAP is rather persistent, as opposed to POP3 that just hops in and hops out. My company of 19 had to tighten control over who uses what and when over it. This alone is enough to make us move away from MS.
2.) You cannot uninstall Exchange 5.5. I boogered up the install once and had to reinstall WinNT because it wouldn't give me the option to remove Exchange and start over. Maybe a little more poking and prodding could have solved it without a rebuild, but I was in emergency 'We need it yesterday!!' mode and didn't have the keys to the company Tardis.
Exchange gets points for being very easy to use and run, but it is a huge moneypit. If I were running on less than 15 people, I'd be fine with it. However, for more than that I'm ready to learn how Linux works and build a server with that.

the concept of exchange (Score:4, Interesting)
Here, we have one Exchange server for 150 people. But then there are 9 locations, from San Francisco to san Diego. They all hit the same server through the wan.
Remote users (15+) also use outlook web access (i't really Exchange web access if you think about it) to access their mail. We have to allow that traffic through the firewall.
And every single one of our people have one or more other email addresses (AOL, Earthlink, RR, whatever).
I would say: have better addressing handling.
Email was first created by geeks for geeks (at univs. and gov.) and served its purpose well. When the move was made to the company, the whole transition was just done wrong.
I say the Exchange servers should be totally eliminiated in favor of a non-lan/wan centric solution (watch your step, marketing words all around), namely a true internet application, shared, replicable, and reliable.
As far as calendaring is concerned, we don't use it much. Our corporate values promote face-time and intelligent conversation more than lines on a spreadsheet, so meetings are more dynamic, more fluid, and less apt tp be "scheduled". Usually it's a phone call.
Anyway, I digress.
But this may be the reason no open-sourcer wants to tackle that issue. It may subconsciously feel flawed to recreate the Exchange architecture.
How to defeat Exchange (Score:5, Insightful)

1. The replacement must support Outlook as a client, people actually like Outlook as an integrated client.
2. The Replacement must work with the Sendto functions of Microsoft Office
3. The Replacement must be able to scale to 10's of thousands of users, in geographically diverse locations.
4. Must Support Multipule languages
5. Must be easily scannable for Virus protection, and must be able to deny delivery of messages that fit certain criteria
6. Easy rules based scripting of mail events stored on the server as part of the user's mail box.
7. Must support enterprise calendaring/scheduling.
8. Must inter-operate with Exchange during migration
9. Must support server and OS of choice at the company(You know what that means)
10. Must offer web mail capabilities equal too or better than OWA(this includes the ability to secure the web mail client via SecureID)
11. Must support massive data stores, on the order of 500GB-1TB(yes exchange can do this)
12. Must Integrate with our directory services, like exchange 2000 integrates with AD.
13 In short it has to do all the things that exchange can do, and more, and better.
Client Side:
1. Must have a client which supports all the functions of the server side. In short its gotta work like Outlook.
2. Must Support OS, and hardware of choice.
3. Easy Rules based scripting interface to server and client side rules(Think Outlook rules wizard)
4. Must be dead simple for users to use, users don't learn they want everything to work just like it always has, even if you give them a new application to do it. When we moved from Banyan Beyond Mail to Outlook when we went from a banyan network to an NT one it was a nightmare for all of the administrative assistants as their workflow was massively changed.

Wild Guess (Score:5, Insightful)
Open source shows a strong prediliction for solving interesting problems well ahead of boring ones. For instance, we had useful, powerful distributed databases, cryptography, new languages and C compilers long before we had a functional word processor and spreadsheet combo. Quite simply, we have already solved mail distribution and address-book sharing on their own, and have relatively little interest in peeling apart a proprietary MS standard for same which is liable to change next week. This is also the reason why OpenOffice is great for everything except reading and writing Word documents.
This flows into my new theory about how Microsoft intends to go about attacking Linux: A deluge of boring, repetitious, pointless APIs and interfaces for problems that were long ago solved but now must be addressed using these new, uselessly variant interfaces simply because that's what everyone else has to do. (Think dotnet.) A hacker's familiarity with extant interfaces is his or her number-one resource, and is therefore that which he or she will part with least readily --- even at the expense of the compatibility or useability of the code they're writing.
Microsoft's strategy is reminiscent, in some ways, of an ancient Incan technique for pacifying politically difficult villages and towns. By forcibly migrating the entire settlement to some distant part of the empire, the usefulness of the skill-sets of these hunter-gatherers was greatly reduced, making them dependent on the (massively centralized) government for handouts, and therefore suddenly rather polite in their relations with the regime.
In the same way that a hunter-gatherer depends on his knowledge of the land, a geek depends on knowledge of the problem and solution spaces. Furthermore, most OSS projects are extremely long-term endeavours; think GCC, think Emacs, think the Linux kernel(*). OSS developers work by building things slowly and correctly with a minimal expenditure of precious manpower; Microsoft works by using more coders, more money, insane work hours and a blase attitude toward standards (even difficult, complicated, important standards) so that they may get to market early , recoup such expenditures, and get to work on the next total (and totally incompatible) revision of their product, which people will use simply because of the upgrade path that MS will kludge together with exactly the same bloodyminded application of superior capital.
Simply put, we need stability more than they do, because they have more time and money. We write things right the first time, whereas they have the luxury of making as many mistakes as they need to in order to grab market share. But more importantly, we need the projects of the past to have been written right the first time; we need a working libc, kernel, and so forth, otherwise OSS simply doesn't happen. Microsoft has no such prerequisites to its growth, as, in a pinch, *it can simply replace its foundations by fiat*. Their hunter-gatherers can, metaphorically speaking, simply create (with a certain expenditure of time and effort) the landscape best suited to their requirements. Thus they can march along beside us, setting the pace, forcing a speedup, replacing good APIs with new because every step into new territory costs them less than it costs us, dissociates us from our well-known and powerful (if somewhat lacking) APIs and encourages our work to depend on their own work, which will then be changed, etc, rendering ours much less useful.
Ultimately, the strategy is designed to encourage hackers to go take up billiards or chess or something with a potential of being useful to remember or think about or use five minutes hence. The ultimate goal of cycling APIs is to induce *indifference*, as we face a choice between working harder on minutia or walking away, hands in the air.
(*)Note that, of these projects, two are sufficiently low-level to be immune to all but the most radical shifts in design; this is again indicative of what OSS excels at.
Replacing Exchange is not a trivial task (Score:3, Interesting)
I think this is part of the problem with any existing attempts or lack thereof to replicate it...Exchange very elegantly handles messaging, calendaring and basic groupware with elegance.
For instance Exchange uses databases with transactional capability to provide extreme scaleability and reliability on the back-end. It has backup APIs that support amazing throughput for on-line hot backups. The database reclaims pages and defragments itself essentially in real time. Exchange supports every protocol in the book...but most customers implement it with their proprieatary MAPI protocol because it actually works a lot better than things like POP3, & IMAP.
Single instance storage allows Sally from marketing to send out her corporate spam to all internal unsuspecting users and the message will only be stored once in the database, there are semaphore links that track who has read the message or deleted it from their mailbox, disk consumption and server I/O load is dramatically reduced, especially when the message is 5 megabytes across 15,000 users!
I could easily come with a design document for a system that would essentially clone Exchange, the problem is around actually programming the system.
You would need a robust database back-end with excellent management support for things like hot backup and real-time database page reclamation, powerful & scaleable MTAs, an arm's length list of supported protocols and APIs, a user friendly cross platform client...
The ability to get all the developpers to agree on how to solve all of the above would be the biggest challenge.

Any serious contender would have to have: tight integration into Windows2000 or *NIX, collaborative calendaring, task delegation/tracking, Enterprise-wide addressing, Public Folders, integrated management, and a client that ROCKS.

Just a few thoughts... (Score:5, Informative)
Essentially I talked about how to get IMAP/POP3/SMTP with a global Address Book and authentication and user accounts via LDAP. I've been watching this space with a lot of interest since then. The lack of updates to the HOWTO should give you some idea of what's changed, not much.
As far as calendaring goes, here's the skinny: CAP is the current IETF draft, and has been for some time, although when it will be finalized is anybody's guess. Why aren't there any shared calendaring servers? Cause there's no shared calendaring standard. You can get asynchronous calendaring in IMAP by having a decent IMAP client and using a Calendar folder, but that's hardly as feature rich as Outlook/Exchange. libical [softwarestudio.org] has kept up with the draft but has no server process. It's used in Evolution and the Mozilla Calendar client. So we have calendaring on the client side, but nothing on the server side. From what I've been able to discern, nobody wants to write a CAP based server till CAP is finalized, since it's gone through too many changes during the drafting process already.
The other problem is the outlook clients. The way Bynari and OpenMail (Contact) have gotten around the proprietary Exchange RPC call stuff, is to write a MAPI driver for Outlook that intercepts the client calls and sends them to the server in whatever proprietary method they might have. Integrating Outlook clients will either require a server side project on the level of Samba or a client side MAPI replacement that uses CAP, unless M$ has a change of heart and decides to support it.
In order to replace the functionality of Exchange you would need, a Calendar Server (none exists in the Open Source world), a searchable document share (WebDav on Apache can't index M$Office documents AFAIK), searchable email w/ public folders and mailing lists (Cyrus + majordomo or Sympa could feasibly work), a global address book (OpenLDAP).
Now,the real kicker, it has to all be integrated, single point of management and have a web interface for users to boot. There are a million and one PHP/Perl based web interfaces to one piece of this or another. However, trying to integrate all of this is impossible. Why?
For starters, everyone seems to want to do LAMP, as if these apps all live alone and users want to log into a seperate web interface for each function then cut and paste data between web pages and not be able to search everything as one data repository, if they can search at all.
LDAP has been available for years, and the guys at OpenLDAP have been there to solve a lot of these problems for years. Quit using an RDBMS for everything, for data that applications should share, use LDAP, stuff like authentication and application user information. LDAP has seemingly been ignored by a lot of open source programmers. Evolution's LDAP support has flat out been broken, everytime I've tried it. Mozilla's works but lacks some functionality. Granted LDAP takes about as much knowledge as learning an RDBMS to understand, but ther are currently about 3 decent LDAP management tools (lape, Directory Administrator and GQ). With LDAP you can essentially have a database schema that all apps can program to, cause it's standardized (inetOrgPerson, etc.)
Other apps seem to be developed without a thought to integrating with other apps. I tried to integrate Sympa, OpenCA, cyrus, sendmail and OpenLDAP with a custom web front end about a year ago. I paid the salaries of myself and 2 other developers for about 8 months, trying to do this. It was a failure, especially in the cases of the Perl pieces. The CPAN Perl libraries didn't do LDAPv3 extensions, isolating code in most of these projects to use a different front end was hopeless and providing an interface to manage the configuration files for the servers was a lot of work. We got about 80% done before I sold the company (and codebase). We had originally planned to GPL our work then sell support and customization, with a calendaring solution and MAPI driver for outlook in the 2.0 feature set.
Most of the frustration we had and was due to using other people's code that was not extensible or modularized. If I had to do it over again, I'd do it in Java on JBoss (esp considering the BEEP servlets JSR for CAP and the great LDAP support via JNDI).
I don't think that developer's of various open source projects need to have some overreaching design group (a la GNOME or KDE) to implement these projects with integration in mind. There are plenty of standards already out there. It just takes some good design and up front research (something I've done a lot of) and thinking about how other developers and users might want to use this stuff for their projects.
Now, I don't want to sound like I'm whining about my own failures, I should have made sure we had enough capital to do it all from scratch. I'm more concerned about our ability to compete with the Exchange servers and Lotus Notes of the world and have a stable, customizable platform that we own. Quit rewriting the same stuff over and over and build new stuff... innovate, be creative, push the industry forward.
There is a glimmer of hope, the Open Source Java community is doing fantastic stuff. I've never seen more modularization, code reuse, integration and faster development in any environment or community. JBoss really takes the lead, the feature list is amazing and I've used it in several corporate environments where it beat out commercial J2EE app servers. JBoss pulls from Ant, XDoclet, Jetty, Tomcat, JacORB, Axis, HyperSonic SQL and a bunch of other projects. Struts and the Java commons and taglib projects at Jakarta are another example of really cool work.
The point is, it all works together. End users don't care if you wrote it in Perl, PHP, Python, C or Java... Just that it makes their lives easier, if we want Open Source to get more places we have to make sure we can deliver on this. Considering most of us make a living programming, supporting or administering networked systems, which would you rather have, propietary crap or really good open source stuff? So next time your designing that project, or writing some more code think about how you can make integration easier. Documentation helps too... we shouldn't have to know fifteen languages and countless codebases to get stuff working together. Most of us specialize in a couple of things.
Well, that's been my experience and is currently my struggle, so hope you get something out of this... BTW, I'd loved to be proved wrong on any pessimism I may currently have.

No calendaring yet, I'm afraid. We're still finishing up the server foundation. As soon as there are some decent calendar clients out there to test CAP (Calendar Access Protocol) with, we'll start building the calendar server.
I am absolutely serious about this project. This is not vaporware.

Eww, sourceforge! Actually, there's not even a webpage- waste of time until there's something I'm willing to put up. ;)
But there are about seventy-five pages of analysis of Domino and Notes in real-world settings, some design documents and a few prototypes of critical components (probably about 200-300h of work so far). I like doing things the right way, which takes time.
Things like Domino and Exchange can be pretty effective if used well, but frankley they're not very smart. My personal research interest is managing the complexity of business and research processes, and I've found that Domino and Exchange don't really help the problems much: they don't help manage the complexities, they simply space-shift them. There's a lot of really interesting and hard problems when you start trying to solve the failings of these two systems. :)

I know that the small software company I work for would love to have Evolution on every desktop (windows and linux) using LDAP for a shared address book and calendar, but it just can't happen today. Oh well, here is hoping that the Kompany can get Aethera right sometime this decade...

- An OSS backend that replaces Exchange for calendaring at least. We can use IMAP and LDAP and such for the other functionality because at least there exist standard protocols, but there is no competetive backend for calendaring applications. It would be really nice to have an OSS all-in-one that does IMAP/LDAP/calendaring, but first things first.
- An OSS front-end like Evolution, but one that works on Windows as well as Unixes.
At our organization (a small university), we are desperately looking for a comprehensive calendaring solution -- one that supports teams, conflict resolutions, notifications, palm synching, and can be used either at home or at the office. I am the OSS advocate in our IT department, but I just can't find a suitable OSS solution. In fact, the only solution I can think of that even remotely fits the bill is Outlook and Exchange.The unfortunate part is that we're using Netscape 4.x here, mainly because of its mail client. (We're using IMAP and LDAP on our backend and NS 4.x Messenger is still pretty good, even though the browser sucks.) Netscape 7.x / Mozilla 1.x is nearly there, but not quite. If there was a calendar solution that worked with Mozilla/NS7 that had those features and had a OSS server, it would be like a dream come true. As it stands, I may have to roll out a small deployment of Outlook and Exchange just to solve this problem (which has come down from the president BTW, so it can't just be ignored until a suitable OSS solution comes along). Now suddenly we're mix-mashing between NS 4.x over IMAP with Outlook and Exchange. You can see what is going to happen with that nice IMAP/LDAP solution in a year.
I think what we really need is a standard protocol, de facto or otherwise, for network calendaring. There is iCal, but from what little I know about it, it's just not comprehensive enough. (Does it deal with network transport?)

AP news story: Someone fired for buying Microsoft!
People are starting to get fired for buying MSFT (Score:5, Interesting)
I know of three people who did get fired for buying Microsoft.
A friend of mine is now providing consulting to the companies in question. Two are running Twig on Linux servers, the other has their old non-ms, non-unix server back up and working (again) while they slowly transition to Linux.
Despite all the "I'll sound wise and neutral if I make out to be 'admitting' free software's flaws and giving Microsoft its due" commentary one sees here on slashdot as either an effort at karma whoring, or an effort at pro-Microsoft propoganda and astroturfing, the fact remains that there are really very few shops that cannot do without Microsoft, and many that actually benefit from running other platforms.
What is very interesting is the number of non-technical people who are coming to realize that, and while they don't necessarilly embrace free software in general, or GNU/Linux in particular, they are beginning to recognize just what a financial, technical, and time drain Microsoft and their products have become to their enterprises, and they are looking for ways out.
Even to the point where, now, people are starting to get fired for blindly purchasing Microsoft, and treating MS propoganda as a substitute for technical research and savvy.
Its a rather refreshing change, actually.

I use IMAP and POP3 through GWIA for 700+ users, off one box. It's been up 60 days, and that's because we moved offices two months ago.
- They still havent integrated GW's user/password database into Novell's famed eDirectory/NDS database.
Maybe not, but I manage them using the same utility. Nobody has anything better, really. And because of the way the post office works, you have to communicate with a specific server agent, not just any server in the tree, so intergrating passwords wouldn't really help any, unless you have no tape backups.
- Very little administrative control over the mailboxes.
What complete bullshit. In NWAdmin, I can control every option of the GroupWise client, I can set it remotely, and I can grey out the option so the user can't change it. What the can't you do? You want to add rules or specific proxy access, just go in to their box with the client, and do it.
- Poor backup solution (you MUST shutdown the email system to get a reliable backup). No, the GWTSA's dont cut it (based on my personal experiences, and statements from senior techs at Novell)...
Not based on my experience with Backup Exec 9.0. Even if you don't use the GWTSA's, you just make everyone access the post office over IP, instead of file access, and backup the directory. The files locked by the agent can be rebuilt from the files that will never be locked.
- Novell has POOR support for automated administration and report generation out of GroupWise - GWCheck just does not cut it...
Hmmmm... I've never cared about getting a report, really. Besides, GWCheck is for repairing the system, not reporting. But since I don't know what kind of reports you'd like, I'll leave this one alone.
Groupwise is *great*. No, I don't work for Novell. Yes, I do administer a 2000 user enterprise system that runs Groupwise 5.5. We don't even need a dedicated e-mail guy, even for all 2000 users. And it doesn't even take up a big chunk of my time. I have 15 domains, 22 post offices, two internet gateway agents, and WebAccess set up. No issues, anywhere.
*ever*
I think you're doing something wrong.
