FOSS alternative to Exchange?


Recommended Posts

Hope this is the right place to ask.

To make a somewhat long and complicated story short, we're looking at moving our company E-mail off of a dedicated appliance and onto a server running some kind of centralized E-mail system. Our support company wants to implement MS Exchange. I do not want to implement MS Exchange. The reasons are mainly licensing costs, closed/proprietary systems, and the fact that I worked somewhere before that used Exchange and had no end of problems with it.

I'm hoping to find a free (as in beer - for the purposes of this topic, consider me unwilling to pay any money at all for the software itself) open-source alternative to Exchange so I can hopefully save the company some money and save myself the problems we had with Exchange at my old organization.

I'm a one-person department, so I'm looking for something that is easy to install, setup, and maintain. I do not have the luxury of reading manuals for more than a few minutes at a time to figure out what I need to do, as my time is already split between about 20 things at any given time of day.

If Exchange really, truly, honestly is the best E-mail system out there, which I frankly doubt, then that's fine and I'll go with it. As it is, however, I'm relatively sure that there must be something superior to Exchange that costs less and avoids vendor lock-in to Microsoft.

Any ideas?

Sounds like your exchange was never set up correctly. In 4yrs at my job I have never had to touch my Exchange 2003 boxes unless I am running updates, and I have 3 servers with email for over 2,500 people.

Why doesn't your company just outsource it's email to a hosted exchange provider? I was in a similar situation to you, having to manage an email server with little time or inclination to learn what was necessary and eventually we switched to an external provider. Ultimately, it costs us less to do that than to put up with downtime and other hassles associated with managing a server without the right experience.

BTW, Exchange is great and I can't praise it enough. Exchange and Outlook make a killer combination.

100% agree with the outsourcing of MS Exchange. You can do this very cost effectively, not sure if it would be cheaper than MS licensing costs in the case of 2500 users. You could either have someone manage your current setup for you (consultant, etc.) or you could move to a hosted Echange model.

I just set up a small business with this service from 123Together, you can go to http://www.123together.com/ to read more about them. I am in no way affiliated with this company.

Also, if you are looking at Free/Open Source, sendmail and postfix are two great options. Exchange is a really elegant solution, especially for calendaring and collaboration (Office Communication Server). Coming from a die-hard UNIX guy, I can't say enough good things about Exchange.

There are plenty of F/OSS mail servers out there, but you are not going to find a free alternative that comes close to replicating Exchange Server. You're really doing this wrong with the 'I don't want Exchange' attitude, because Exchange truly is a brilliant piece of software. I'd echo the reccomendations for a hosted exchange solution.

+1 Zimbra

We are in the process of mirgrating to Zimbra, having set-up a Zimbra server I can say that it is a joy to work with.

I would be happy to help with any questions you might have but Zimbra would be something you should look into ASAP.

Thanks for all the input. I'm not sure about hosted Exchange, I'd kinda prefer to keep things in-house if possible. I think I'm going to have to take a good, long look at the latest version of Exchange and see what all it has to offer, since it seems to get high accolades around here.

Also, with regard to Zimbra, my next question is to the point of client-side compatibility. Will Outlook work with Zimbra as more than just a POP3 client? What about calendar sharing? BlackBerry syncing? And the big one - does Outlook interoperability cost money?

Also, if we go with Zimbra, I'm planning on running it on a Linux server (which may actually be a requirement, as I can't recall offhand if there was a Windows version or not). Is there a distro that's particularly well-suited to run it? Debian, Slackware, SuSE, Fedora...?

Thanks again!

Generally, for server work, I would go with something a little less consumer-y. You don't need the latest "packages of the day", and want stability and a proven, tested track record.

Something along the lines of Red Hat (it is popular and built for servers)? Use the free clone of it: CentOS (Y)

I run CentOS 5 on a server here at work. It runs an internal wiki and a Subversion respository. Had no troubles with it. Another option I would suggest is the latest Ubuntu LTS release. What I do like about CentOS is the gui based tools for configuration.

    • Millions of users to benefit from Windows 11's new performance boost on Adobe Photoshop by Sayan Sen Despite the advent of AI-generated imagery, Adobe's Photoshop remains one of the most popular tools on this planet. Adobe does not have a publicly reported total user count but it's probably not wrong to assume there are millions. As of 2025, Adobe Creative Cloud has had approximately 41 million paid subscribers, many of whom likely use Photoshop. In addition, more than 166,000 companies worldwide are apparently also using the app. These figures are according to a very recent report by SQ Magazine. Out of them, it is fair to assume that many are probably running Windows. As such, there is good news for these users as Microsoft has announced Photoshop is getting a big 20% performance boost on x86-64 (AMD64) systems and a 13% bump-up on Arm devices. This is definitely great news for them as many have complained about the slow performance and general sluggishness of Photoshop on Windows 11 ever since the advent of the latter back in 2021. If you are wondering how Microsoft managed to do this, the answer lies in a combination of compiler-level optimizations and a technology called Sample Profile Guided Optimization (SPGO). According to Microsoft, Adobe worked closely with the company’s Visual C++ team and adopted the latest MSVC toolchain enhancements together with SPGO to squeeze more performance out of Photoshop’s CPU-bound workloads. Unlike traditional Profile Guided Optimization (PGO), which requires developers to create special instrumented builds and run lengthy training workloads, SPGO gathers performance data directly from optimized release binaries. This means Adobe could collect real-world usage information which gives a major advantage to this technique, as companies could leverage data collected from actual customer workloads rather than only relying on synthetic benchmark runs. In theory, this should allow optimizations to better reflect how users interact with software in the real world. Thanks to this, there are improvements to code layout, function inlining, hot-and-cold code separation, and other low-level tweaks that help processors execute instructions more efficiently. Essentially the compiler is better able to identify “hot” code paths, those which are most frequently executed, and optimize them accordingly.
    • "The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months¨ I'd prefer to see the lowest price in over a year
    • Glad these prices are starting to come down, but that is still crazy. I bought the 2TB 9100 Pro (slightly more expensive version with PCIe 5.0) last year for $240.
    • The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months by Sayan Sen Yesterday, we covered a really good deal wherein you can get a 4TB TeamGroup T-FORCE G50 NVMe PCIe Gen4 SSD for a low price of just $400 with a special discount coupon. That's just $100 per TB, making it a very good offer during these hard times. The deal is still live, so you can check it out in its dedicated article here if you do not want to miss out. Meanwhile, if you don't have that kind of budget but still wish to buy an SSD for a good price, the 2TB variant of the TeamGroup SSD at $280 its lowest price in over three months. Meanwhile, those seeking 2TB but faster performance can check out Samsung's 990 PRO, which has hit the lowest price also in the last quarter or so, as it's on sale for $370 (purchase links under the specs table down below). Thus, you want a faster drive, get the 990 Pro, or you want more capacity, grab the TeamGroup 4TB linked in the first para. The 990 PRO is a PCIe Gen4 NVMe SSD and still one of the fastest drives available today for under $500. Speaking of fast, sequential reads and writes are rated at 7450 MB/s and 6900 MB/s, respectively. The random throughputs for reads and writes are 1400K IOPS and 1550K IOPS, respectively. The 990 PRO is based on Samsung's 7th Gen V-NAND flash, and it too is TLC. It packs 2 gigs of LPDDR4 DRAM cache, which helps the random performance. The endurance rating for this is 1200 TBW (terabytes written), which should be sufficient for most users. The Samsung 990 PRO is compatible with the PlayStation 5, but if you are going to use the 990 PRO on a PC, check out the Samsung Magician app that lets you track your drive's health, update its firmware, customize various settings, and more. The tech specs are given below: Specification TeamGroup T-FORCE G50 2TB Samsung 990 PRO 2TB Interface PCIe 4.0 x4, NVMe 1.4 PCIe Gen 4.0 x4, NVMe 2.0 Form Factor M.2 2280 M.2 2280 Controller InnoGrit Controller Samsung In-house Controller NAND Flash 3D TLC 3D TLC DRAM Cache None (HMB supported) 2GB LPDDR4 Sequential Read (Max) 5,000 MB/s 7,450 MB/s Sequential Write (Max) 4,500 MB/s 6,900 MB/s Random Read (4K) Up to 600,000 IOPS Up to 1,400,000 IOPS Random Write (4K) Up to 700,000 IOPS Up to 1,550,000 IOPS TBW (Endurance) 1,300 TBW 1,200 TBW MTBF 3,000,000 hours 1,500,000 hours Operating Temperature 0°C to 70°C 0°C to 70°C Storage Temperature -40°C to 85°C -40°C to 85°C Shock Resistance 1,500G / 0.5ms 1,500G / 0.5ms Heatsink Patented Graphene Heat Spreader No Get them at the links below: Samsung 990 PRO SSD 2TB (MZ-V9P2T0B/AM): $369.99 (Sold and Shipped by Amazon US) TEAMGROUP T-Force G50 2TB SSD (TM8FFE002T0C129): $279.99 (Sold by TeamGroup, Shipped by Amazon US) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.
