Good morning all.

I am thinking of using Kerio as my email server for 4 companies under the one mail server.

What I am after is some opinions of whether I should use Kerio or not.

My other option for a email server was Alt-N.

But I like the ease of the interface of Kerio compared to Alt-N.

The Business is made up of 4 companies. Total 30 users for now.

So they will all use the same email server under there own domain.

I am after some opinions on stability, general use, performance of the server, Outlook connecter performance.

Thanks

Administration is superb

Extremely stable & reliable

However the Outlook Connector performance is terrible although we have some hope that the cachedmode KOC will be available within the next several months. The public beta should be available sometime soon.

Much better than MDaemon apart from the Outlook connector

I've had no problems with running Kerio for a company with 150 users across 2 domains at 4 locations for the last 5 months.

The web interface works very well, and administration is intuitive.

Support is not always easy to get quickly, but the personnel have been friendly and helpful.

From what I can gather, changes to the program are infrequent. If you're looking for a feature that Kerio does not have but plans on in future releases, don't hold your breath.

Outlook connector has a few bugs and is slow for large mailboxes, but is not unreasonable even with a WAN connection with my rather small mailbox of 360 Mb and 15,000 items across 100 folders.

I moved from Exchange 5.5 and I wholeheartedly recommend Kerio.

Only comment about not holding your breath is in regard to the KOC Offline Edition. This is a real product that is currently undergoing vigorous testing before release.

Kerio, as real substitute to Microsoft Exchange, is not ready yet.

Like it has been mentioned before, administration is very good, and the web interface is superb. The spam filtering is probably one the best in the industry - you can run Kerio standalone with no additional third party products or spam appliances. Staff are very friendly, but a little slow to respond.

But if your users currently use Outlook, moving to Kerio is going to be a real shock for them to the point that they may refuse to use it using the KOC. The company does a poor job of keeping their customer base informed. The Knowledge Base is pretty useless (because it is not routinely updated), and the documentation requires you to print it out, and keep notes in the margins in order to demystify some of the configuration.

The biggest problem with Kerio is the support for Outlook. From my experiences, it is terribly slow, to the point where people are forced to use the web interface on connections that are slower than 100Mb LAN conditions. If you have offices that are remote from the server, they will not be able to use Outlook. Sorting and searching support is poor via Outlook, but several of these issues are due to the current version of the Kerio Outlook Connector, which apparently are being fixed in the next version of the KOC.

Deployment of the KOC is an administrative hassle - expect to visit every workstation to install and configure it. There is no auto configuration support. The password for a user account is embedded in the KOC, which I believe to be an important security issue.

The KOC has a few bugs in it. For example, every time you enter configuration of the KOC via Outlook, the KOC might generate a new toolbar for the Spam filtering buttons. After a few times, you end with half a dozen or more of these toolbars, all with the same two spam buttons.

Support for Palm devices is spotty at best - but honestly, I don't think it's Kerio's fault. Expect synchronization problems using the VersaMail app for older Palm Treos (like 650 and 700P).

Calendar support has some holes. For example, recurring appointments cannot be individually modified in either Outlook or the web interface.

Custom categories are not supported. They will be visible in Outlook, but you cannot do anything useful with them.

Tasks are not properly supported. You cannot send a task request to another user and have it behave as it should in Outlook, such as putting the task due date in the Calendar. Basically, Kerio reverts the task request to a plain text e-mail message, which in itself is meaningless to the system, and ultimately redundant to a regular e-mail message under Kerio.

Support for flagging e-mails (e.g. for follow up) is very poor.

Auto-forwarding based on rules is somewhat limited and weak. Expect to find or author some POP3 software if a business system depends upon it (like automated processing of e-mails based on content).

As an e-mail server, Kerio is one of the best. As a collaboration system, Kerio is just not ready yet. We researched Kerio and other mail products very carefully, and Kerio was found to be the best, based on all factors, including administration, support and pricing. If your users don't need Outlook, then Kerio is an excellent choice.

That is true however some of those issues have been corrected with 6.5 which is in the 7th beta.

6.5 is looking good hwoever I predict many more betas and patches after its been released and by the looks of it most of the focus has gone into KOC.

Generally Kerio does an excellent job, we have 3 domains and over 500 accounts. Administration is excellent, like most before, support is slow to respond at times. I was never able to get the Outlook Connector working properly but then again I wasn't given enough time to fully trouble shoot etc. We're running it on a P4 with 1g of ram running XP Pro. Webmail interface is excellent and we have about 1/3rd of our users using that interface exclusively. In the last 3 years as far as I know we haven't had any reliability problems, sure we've had issues and occasional strangeness, but the server has been very very stable. After hearing about 6.5 assuming it's fully tested and sorted before final release, I can't think of any reason why not to use it.
