Fjan11 writes "Over 150 man-years of work were added to the Open Source community today when Zarafa decided to put their successful Exchange server replacement under GPLv3. This is not just the typical mail-server-that-works-with-Outlook, it is the whole package — including 100% MAPI, web access, tasks, iCal and Activesync. (The native syncing works great with my iPhone!) Binaries and source are available for all major Linux distros."

[+] Ask Slashdot: Is There a Linux Client Solution for Exchange 2007? 385 comments
CrazedSanity writes "I have been working at my state job for about 7 months now, using the Exchange plugin for Evolution to check my email. Very recently the higher-ups decided to migrate to Exchange 2007, which effectively destroyed my ability to check my email through any method other than webmail (which means I have to constantly refresh/reload the webmail window). I'm sure somebody else has encountered the problem, but I'm wondering if anybody has come up with a working solution?" Note: CrazedSanity's looking for a client that will work with Exchange in a situation where replacing the Exchange install with an open-source equivalent isn't an option.

    I seem to remember ogo being a full replacement and that's been out for a while. Also, although you want to provide compatibility with Exchange, don't you want to provide additional capabilities so that Exchange systems are forced to upgrade to you, rather than the other way round? (Embrace-and-extend, but non-toxic.)

      There are plenty, but most seem to miss the point of Exchange in some fashion.

      Point the First: Everything that you're likely to plug into Exchange must also work with whatever alternative or it isn't an Exchange alternative. That means things like Blackberries, other vendors' smartphones, seamless (yes seamless, not "install this plugin which sort-of works") Outlook integration, remote management of smartphones (including wiping them). Zimbra's pretty close here, but falls down on remote smartphone management and seamless Outlook integration.

      Point the Second (Scalix falls down here): Exchange is only a small proportion of the overall licensing costs. You've also got Active Directory (which implies a Windows Server infrastructure) and CALs for AD. There's not a lot of point in having AD without having your workstations on an AD domain, so you've got to factor in all the necessary licenses for this as well. If you demand I supply my own AD infrastructure and you price your product at [price for Exchange - 10%], I might as well just pay the extra 10% and eliminate the risk of being passed between vendors in a game of telephone tennis in the event of support issues.

      Point the Third: Whether you like it or not, the PHBs who like Exchange are often rather stuck in the Exchange way of thinking. I don't care how much better you think your solution is, if your argument is "it's cheaper but it's only better if you're prepared to accept a totally new way of thinking about groupware" then it's not better because the PHBs in question probably aren't. Citadel's a good example of this.

        Jesus H. Fucking Christ. 99.9999999% of all companies just want to buy a tool that works. They don't want to build the fucking thing. They don't even want to fix it. That's why they buy the support license. This whole 'we can customize the code if we want' is a huge stinking load of specious crap. Companies of any size BUY their software because they don't want to customize software they don't have to. Like office software. Customizing a huge billing system is one thing (if you are a big enough company to warrant doing that), but why would an insurance company, or a local widget maker, or a medical clinic want to become an email server programming company???? Get a grip. They'll go out and buy exchange or lotus notes or whatever because they just want the frickin tool. And if it is buggy so what? It works for the most part and they don't have hire programmers or keep programmers around to fix bugs that said programmers introduced when they screwed around with the source code. It's cheaper to pay for the licence for a year than to pay for an unneeded programmer for a year.

          it's around 2,400-- but then you also require 25 outlook licenses.

          once again, the price of the software is negligable compared to the cost of 25 employee's salaries...

          go ahead, waste a week of each one's time teaching them whats different about the new program.

          This is server software we are talking about here. The end users don't change their software (that's the entire point). So there is no cost for retraining end users.

          You would obviously have to train the server administration staff, but even if you did put in a "Genuine Microsoft" Exchange server, you would probably still have to do this.

          Besides, even if the front end did change, a week of training is a LOT. As it would be replacement software, the concepts are the same, it's only which button you push to do it that changes. So if you can't train them in a matter of hours, if not minutes, you really do need new employees.

          Where I work, we use a non-MS stand alone calendaring solution. Our end user training takes a couple of hours.

          How long do you think it would take to train users to use the new version of MS Office?

      I don't think it is a very big deal. I've supported Exchange servers in companies of various size, and it's really not doing anything astoundingly complicated, and what it does it doesn't do all that well. But still it does a bunch of things that other solutions haven't done an even worse job at, and does them all together. Things like "I can send a meeting invitation to my boss and his assistant can check his mail, accept his invitation, and reply on his behalf without actually logging in as him."

      I know, it doesn't sound like that sort of thing would be all that important, and it's not even clear all the time that it makes a lot of sense, but there are companies that run on this sort of procedure. So there are a bunch of random things like shared calendars and push-email to phones that people don't want to live without, and unless you can provide a seamless replacement, you're stuck with Exchange.

      I, for one, am eager to see a suitable Exchange alternative. I have a real love/hate relationship with Exchange. There are some options out there, but none of the options I've tried have worked out.

            Well, the reality is that senior executives have always had personal assistants (used to be secretaries) who really opened all their mail, sorted it, and typed responses to the mundane, and took dictation for the serious ones.

            The executives typically have 100% trust in their admin's and this feature is absolutely necessary to the proper functioning of a senior management team. It may seem like a security risk, but in the cases that I am aware of, both users are aware of their status, and it rally operates like it did in the pen and paper days.

            Messages sent by the assistant have a clear "Bob accepted on behalf of Alice" kind of structure. The logs also show that it was Bob accepting on behalf of Alice, IIRC. This is useful not only for the tracking perspective, but also so that the recipient knows that it was not necessarily directly handled by the person invited.

            Having others able to act on your behalf without using your login simplifies the process of proving that you did/didn't actually do something. The information about who logged in and did what on whose behalf can easily be logged. If, on the other hand, you have a system where your login has to be used to act on your behalf then the logs can only show your username no matter who actually used your account.

            If others can act on your behalf without actually logging in as you, what proof is there that e-mails allegedly sent by you were actually sent by you?

            If others can be delegated permissions to act on your behalf in specifically designated manners without logging in to your account, then, if the system logs who did what under what account, there will be accountability.

            OTOH, if others can't act on your behalf without logging in as you, and you have a business need them to act on your behalf, you have no choice but to give them your access credentials (dongle, password, whatever) and then there really is no accountability, and no control over the manner in which they can act on your behalf.

            So, rather than destroying accountability, supporting delegation enhances accountability (and security).

      To answer your question, IMHO the big deal is collaboration, productivity, integration, and a lot of features "just work"*. I'd wager to say that the majority of medium to large companies use MS Office and MS Outlook as their productivity suite and e-mail client respectively of choice.

      Collaboration
      Setting up meeting requests are simple. I can easily see other people's calendars so I can pick the best time and I can even set a meeting location which will automatically reserve something like the meeting room for example. Meetings automatically get put on my calendar as tentative and I'll receive a notification in case I forget to accept the invitation. Updated meeting change my calendar as well without intervention.

      Productivity
      I can set reminders, flag e-mails for follow-ups, create folders to organize, create processing rules to eliminate common tasks. A lot of rules will run on the Exchange server without the need of a client running and I don't get unnecessary e-mails on my phone. Outlook maintains a constant connection with Exchange so e-mails are sent and received nearly instantly.

      Integration and crap just working
      Obviously most MS products can seamlessly integrate well with one another. In the latest version of Outlook I can preview a number of attachments within Outlook without actually opening them up in their designated app, thus a new window. I can set a folder to actually open up a webpage within Outlook to "Integrate" a webapp or just be sly on reading Slashdot.

      Phone integration really is a big one for me. Using a WM5, WM6, or iPhone with Exchange ActiveSync is almost the best thing since sliced bread. I remember the days of having a PDA and the PITA it was to do a hard-reset or get a new one. Even getting a new phone and having to manually enter in each contact sucked (I've been a CDMA whore for eight years). All my contacts are kept on Exchange and this allows me to reference and edit them via the phone or Outlook. Having to do a hard-reset or get a new WM phone is no big deal; a three minute sync with Exchange over the air gets me all my contacts back and access to my e-mail. The rare third party apps I use are kept on an SD card. Life is easy getting the execs and lusers up and running as well.

      Integration with Active Directory (LDAP) makes my life as an admin easier with GPOs and groups to divvy out permissions. And for some reason all this stuff works without much hassle.

      The bad
      Exchange and Outlook truly do have their faults. If I were to have my own company, I can't honestly say that I would run them. I wont get too far into the bad since I'm running out of time with the wife waiting on me. If I were to have my own company, I can't honestly say that I would run them. Exchange works great with communication within itself and other Exchange servers. It does a decent job at SMTP transmissions most of the time. The big headache I have right now stems from a tech at MS telling me that "the RFCs for the SMTP protocol are merely suggestions." It's not like SMTP is overly complex; there are only a handful of commands that are exchanged within SMTP communication and Exchange even F's that up. And don't get me started with how Outlook is written in VB.

      I'm glad to see some open source Exchange clones out there. I'll eventually run one of them for my server at home just so I can keep my contacts synced when I leave my current company.

      To put things into perspective, I'm not a MS fanboy, but I'm not a MS hater either. I know their products well and is a part of my profession. My real passion is UNIX; specifically FreeBSD and OpenBSD. I try to introduce them where possible and applicable. Not to mention there is some stuff I can get done easier and faster with UNIX than I could with MS Windows. Other products out there are just as buggy and bloated as MS's; they just get more attention since they're more widely used.

      I hope that Zarafa and others continue to innovate and make a nice profit. Competition is good for innovation and lowering prices; both of which benefits us consumers.

      * Setup can be a RPITA. When something doesn't work as expected it can be an easy fix or cause suicide.

  • by Anonymous Coward on Friday September 19 2008, @04:53PM (#25078817)

    I've not looked at this software, but Exchange is one hell of a piece of machinery. Say what you want about MS, but I've seen an Exchange server with terabytes of email, gigabytes per day, keeping up fine. It's a pain in the ass sometimes to be sure, but I wouldn't trust my production network to this today anyway.

    • Say what you want about MS, but I've seen an Exchange server with terabytes of email, gigabytes per day, keeping up fine.

      BS. I've seen Exchange servers with gigabytes of mail and megabytes per day roll over and cry until we put a FreeBSD/Postfix/Amavis/ClamAV server in front to lighten the workload by 95%. If this is built on top of FOSS components, I don't doubt for a second that it'll run rings around Exchange.

      Exchange has traditionally had exactly one reason for its popularity: vendor lock-in. If this really is a drop-in replacement without annoying CALs, we'll be Microsoft-free on our servers by Monday.

      after working the storage industry I have come to the conclusion that exchange is not very effective at handling heavy email load or large message database. How many of us get annoying emails when we have more than a few hundred MB of messages in our mailbox? Did you know that Exchange performs like crap when you run low on local disk space to keep the data. CIFS won't save your ass either, you end up having to go to using SAN (which looks like local disk from Exchange's point of view).

      Some bullshit scripts with postfix, exim or qmail can spool and forward terabytes of email an hour. With the added advantage that you can cluster your IMAP services out to deal with the space and load in an incredibly simple yet scalable manner. You can use a SAN, but you can just as easily setup a new box for every 100 employees and still have a very usable system.

      Exchange is inflexible and can only scale if you use on particular (and very expensive) setup. Microsoft only focuses on the operating modes of Exchange server that they use at corporate HQ. The inferior modes are just there so they can sucker companies into buying it at the low end, when in a short while the company will have to invest an exponential rate of money to scale the system.

      The TCO of Exchange is very high. And Microsoft's way is not the only way to manage messages, events, meetings and users.

        What do you say to the Hundreds of Thousands of clients who get their Exchange via SBS (Small Business Server)? And that's just the 2003 version.

        How many Enterprise apps do you know of by ANY vendor that dont degrade with low disk space? Come on, dude, that aint fair and you know it.

        Exchange is one of those apps that can look bad if installed by an idiot. You would think a proper architect would have worked out space and usage requirements early on.

        How do you reach a low space condition ANYWAY, if you are making proper use of quotas? No product takes more abuse due to stupid administration than Exchange server.

        But please, inflexible? When you have dozens of 100K+ client installations of Exchange humming along at places like Chevron and others, while the very same product can keep 20 people happy on a $500 box, you cant call it inflexible. Thats just wrong, pal.

            So tell me; did you present your management with a cost/benefit analysis, supporting your request for additional hardware? Did you point out what a catastrophic failure of the Exchange infrastructure would cost them in lost man-hours and productivity? If everyone in your company is getting "mailbox -full" notices, it would seem to me an easy argument to make in DOLLARS, as to the amount of time spent by staff just to find items to delete each week. Am I wrong?

            Have you looked into tools like GFI's Mail Archiver or the Mimosa tools to get you some disk space back, and bump up overall performance?

            See, it is very easy to just say, "management sucks, exchange sucks, yada, yada", but until or unless you have done all you can do to make your case, I repeat: IN DOLLARS, you have to bear some responsibility. This is what is wrong with IT these days. I'm guessing you didnt do a cost analysis, and you would not be alone in that regard, but someday, IT folks are going to have to prove that we are REAL professionals, or management has no good reason to pay any attention to us. IT is not just about technology, you have to sometimes be a teacher and a salesman to be effective, even when Management makes you not want to really give a shit.

            Personally, if you had done what I suggested, and gotten the response you described, were I you, I would have walked out of there, before I let anyone put my name on a fucked up server.

    As a former MAPI programmer (don't worry - I've largely recovered) I have to point out that this is utterly irrelevant.

    The only compelling reason to use an Exchange compatible server is to support Outlook. The issue is that Zarafa charges for the Outlook connector. This is not a new business model, people, and truth be told its been a fairly common paradigm of 'Exchange-killers' for quite awhile now. Nothing is killed until the connector is free. Full stop.

    So why doesn't anyone offer a free connector? Because it is ridiculous amount of work to build and it is something corporations are willing to pay for. It's not that replicating the server functionality is difficult, it's that Microsoft twisted and violated open standards into something utterly unholy known as Exchange to ensure that nobody but Microsoft could communicate with it. MAPI is Microsoft's obfuscation of traditional messaging protocols and is infamously poorly documented.

    I wrote about this issue for Redmond magazine about 2 years ago and nothing's changed. The connector is still the kicker and, regardless of how nifty the back-end is, until an open-source Outlook connector appears Exchange will remain one of MS's top 5 products.

    Nothing but PR to see here. Move along...

      Hey, look! FUD!

      • If FSF considers it to be free software, how it is not free software

        One of the requirements of Free Software [gnu.org] is "[t]he freedom to study how the program works, and adapt it to your needs (freedom 1)." The Affero GPL explicitly denies this freedom:

        If the Program as you received it is intended to interact with users through a computer network and if, in the version you received, any user interacting with the Program was given the opportunity to request transmission to that user of the Program's complete source code, you must not remove that facility from your modified version of the Program or work based on the Program, and must offer an equivalent opportunity for all users interacting with your Program through a computer network to request immediate transmission by HTTP of the complete source code of your modified version or other derivative work.

        I don't care who endorses the AGPL; by the FSF's own definitions, it is not Free Software. Get pissed off and mod me down all you want, but that doesn't change the fact that the AGPL is a EULA in that it governs the behavior of people who merely run the software, even if they do not distribute it (by any reasonable definition of the word "distribute" that has been in common usage during the history of computing).
