This review was originally posted on VersionTracker.com. I've been using Kerio for a long time at my organization and we recently had to switch back to Communigate. Now that the pricing structures are more on par with each other, we just couldn't manage without some key features anymore. First let me say that Kerio is great for basic-to-intermediate-level deployments. It's super easy to use, easy to delegate management, and represents a solid, set-it-and-forget-it mail server.
For more complex deployments though, it starts to underperform compared to its counterparts. In particular, there's virtually no server-side scripting at all. As such if you want to set up any kind of server-wide rules, you'll generally need to pre-process all of your incoming mail. The logging also leaves much to be desired. If you need to track the progress of a given message through the server, you're limited to just logging the arrival of the message, you can't really see what happens once it's accepted.
One of my biggest pet peeves is the rigidity of the configuration controls. As one example, if you have an organization that has multiple brands and, as such, multiple domain names, you're going to have a lot of trouble setting up a group address that spans these domains. You essentially have to create a dummy account (which eats up license seats btw) in each domain that forwards to a group address in each of the other domains because the interface doesn't allow you to add an email address to a group--you can only add a registered account that is a member in the same domain. You can, however, add an email address as a forwarding address for an account, hence the above workaround does the trick. As well, a group address cannot have another group as a member so there's no grouping of groups available without a workaround either.
These are just a few of the examples of trying to figure out how to do things that used to be easy--a practice I found myself doing too often with Kerio server. As such, for a solution that's priced in the same ballpark as some other major players now, I can't recommend it for organizations with complex needs.
This review was originally posted on VersionTracker.com. I have just finished moving over 16 email accounts from my cobbled together Mac OS X Leopard Server on an Xserve to running Kerio on a Mac Mini. Other than the obvious difference in throughput (Xserve vs. Mac Mini), I am very, very happy with this product.
I had to learn so much to bring everything up to snuf on the OS X's setup, that I ended up ditching the GUI in Server Admin and only hand code all of the Postfix configuration and have an extensive Perl script for learning/unlearning Spam through SpamAssassin. I works great, but it was not easy.
Then... I got Kerio. What a breeze, and backed up with good documentation (even if the writer's appear to have English as a second language at times)! Of course now I know what I am doing, coming from OS X Server's world, but that makes it all the more clear how much more 'Mac' Kerio's implementation is than Apple's. Apple should buy Kerio, then create an integrated Office/Exchange(Kerio) suite for the business world. That would bury Microsoft, whose real stranglehold on the big business sector is Exchange.
Back to Kerio. My only big beef is there was no easy way to teach the Bayesian SpamAssassin filter like with a normal SpamAssassin install. So, it is only set to auto-learn, and I couldn't move my existing SA database over with its 3 year's worth of learnings, which has led to more spam for the moment.
The webmail client is very good and polished (much better than OS X's venerable SquirrelMail), but lacks real email interface items, like 'redirect', 'forward as attachment', and there is not way to 'blacklist' with SpamAssassin as a webmail user, only as an admin.
The administrator console application is great and well thought-out. I use it on my Mac Pro at work and another one on my Mac at home to admin the Mini. No problems so far.
I highly recommend this for small to medium business with limited resources, especially since you can get the groupware benefits without buying the full version of Entourage for everyone like we did (the Home/Office version does not have Exchange support, though works via IMAP just fine). You can skip Microsoft and use a mixture of Apple's software, but I have not tried this.
I also recommend getting DNSEnabler to quickly setup a DNS server on the same Mac you run Kerio. This way, any laptops can access Kerio directly when at work, then remotely through secure channels when outside work. Easy as pie with Kerio's service setup. I also installed a cheap GoDaddy SSL certificate (check the docs on that one, especially the install of intermediate certs). Works great, even with the Microsoft products.
This review was originally posted on VersionTracker.com. This is an excellent alternative to OSX Server's postfix/cyrus open source setup. For me the deciding factor was that it allows groupware functionality a la Exchange for Entourage users on Mac. That is, it allows shared contacts, calendars, etc., within a group of designated persons. The only limits seem to be those imposed by Exchange/Entourage, not by Kerio. Many other features. A fair licensing price structure. Excellent support: even BEFORE I bought Kerio, their tech support called me (yes, called me) and offered to help resolve an issue I was having.

Version: Kerio MailServer 6.2.2
This review was originally posted on VersionTracker.com. I only have good things to say about this server. Exellent support and fast updates to problems. New features added all the time. Nice intregration with AD and OD servers! The webmail is almost as good as a standalone mailclient. The perfect mailserver for small / medium firms that want groupware functionallity similar to Exchange.

Version: Kerio MailServer 6.2.2
This review was originally posted on VersionTracker.com. Although the web mail client is missing a lot of little features, Kerio Mail Server is an excellent choice of a standalone suite for people who don't want to dive into the CLI world of Postfix.
The Admin Console is straighforward and easy to use. Support is very good.
It's been running for me non-stop for 3 months without a hitch in an Enterprise environment with almost 80 IMAP users on 2 domains. It has no problem talking to our Barracuda Spam Firewall. Stability is rock solid.

Version: Kerio MailServer 6.0.6
This review was originally posted on VersionTracker.com. we now use kerio mailserver 6 for 2 weeks and it runs solid as a rock. very easy to configure and to handle. i looked for a new mailserver for nearly 6 months and this is all you need for a little company. Anti virus is perfekt, so is spam selecting.
Great product. we buy it today.

Version: Kerio MailServer 6.0.5
This review was originally posted on VersionTracker.com. There are very few mail servers outside the telco grade market that are really solid, complete and light. I have to say that I like its support for HP/UX and linux, not speaking about XRAID on Mac OS X which is according to me the most solid and cost effective way to run a good mail server. And it took only 2 minor releases for them to fix a non critical bug I had reported earlier, that was fast. Finally I run a messaging company since 10 years, our customers are demanding telco operators, also i wrote a mail server a few years ago, so my positive review takes many factors into accounts.
Now compliments never come for free so I take advantage to ask for a new feature: AppleScript or any kind of java scripting engine in the server would be awesome. This way we could expand it easily when having the technical resources to do so.

Version: Kerio MailServer 6.0.1
This review was originally posted on VersionTracker.com. Though this product has a few little quirks, it is an excellent product for the Mac. Other bad comments on here for this product are from people who don't know how to use a Mac.
The webmail has an incredible interface and very easy to use, unknown to other mail servers offered on the Mac. There are some quirks right now with the Entourage (exchange connection) and this mail server. A condensed easy to use server administration program, which is very useful compared to the built in Mac mail server.

Version: Kerio MailServer 6.0
This review was originally posted on VersionTracker.com. Everytime I install an upgrade my user's passwords get wiped out. Tech support is not much help - that is they never resolved the issue. I would think twice before putting this into production.
