Me too. I put in a feature request for this a long time ago, but I doubt that it will ever be implemented.

Don't you like existing set of supported anti-viruses?
Why is ClamAV better for you than others?

ClamAV is "free"
With no Windows machines on our network, it really isn't much of an issue to have anti-virus software with KMS. However, it would be nice to have an option on OS X that isn't ridiculously expensive (SAVI - $750 for 50 users, and we only have 20!) I would not like our network to be responsible for passing on malware even if we are not directly effected by it, which is why ClamAV would be a good option with KMS on OS X.

Another good reason is that ClamAV appears to be faster at responding to threats:

I like Clam AV, it's free which is nice. I switched my office to Mcafee enterprize years ago, unfortunatly KMS won't use the license I pay for and I am not willing to pay again. I really wish you would allow us to use our own desktop version of mcafee as part of the mailserver.

Even if it would work through KMS, the licensing would not with McAfee. For a mailserver level scanner, you have to get licensing per mailbox. A desktop license won't due.

My point is more that I wish I could point Kerio to the scanner I want to use. Many pieces of software do that.

You can. Just not ClamAV. The problem with Clam Av is 1. it's fairly new, with no established track record, and 2. It's an open source project that hasn't even hit a 1.x version yet. That usually means it's still in development, and subject to change frequently.

I'm not knocking open source software, I use a lot of it myself, but as a developer, I wouldn't want to build in support until a product has at least hit a 1.x milestone or higher, and has a proven track record behind it. Right now, they have a new release at least once a month, sometimes 3-4 times a month. How can you support a product that changes faster than you can update your built-in routines for the last version. That's a support nightmare waiting to happen, and, well... no comment there.

Apple manage to support it with Tiger server. Other mailservers use it too (4Dmail for example). I don't think it is the issue of being a 'pre 1x' release, more the fact that if Kerio offer it, it may upset the other vendors who currently supply plugins for KMS because it's free.

That's also a possibility.

Tiger is made up of Open source software, so supporting open source AV isn't a supprise. Both 4Dmail and Tiger also only run on Mac OS. That could be a factor as well.

If I'm not mistaken, ClamAV is native to *nix, and ported to Windows. That could have an effect as well since a lot of the dependencies are native to *nix.

Clam is *nix only (native). If you look at the number of AV scanners available for OS X under KMS, you will notice that there is only 1! Surely the server platform for KMS needs to have more options? There are plenty of scanners available for windows, so if Kerio only supported Clam on *nix servers, then that's ok with me!

That's a very valid point. There should be more options on OS X.

No offense, but I have to take issue with several things you said:

1.) ClamAV is not really "fairly new". We've been using it for years on our "mail firewall" and it's extremely popular in the (huge) open source mail server world. It has quite a track record and is the de facto AV solution in the "open source world".

2.) ClamAV definitions are usually kept up-to-date even moreso than the commercial alternatives.

3.) 1.0 means different things to different developers, and sometimes even different things to the same developer depending on the project. For a perfect example of this, see Firefox, which was used for what, a couple of years prior to 1.0 by a lot of people.

4.) Most software products are always "in development". ClamAV certainly is, but its being used in production all over the place, and again, is extremely popular.

5.) You don't have to update with every release or snapshot. On our "mail firewall" box, we simply apt-get update every 6 months or so, unless there's some serious security flaw.

6.) Users don't deal in APIs, so they don't have to worry about "changing routines", etc. They simply install it, schedule freshclam, point their mail server stuff to it, and let it go. It's simple and painless to setup and install.

7.) Kerio "supports" SpamAssassin which seems to have a similar development schedule. You'll note that they don't update KMS every time a new SpamAssassin release comes out.

Again, I don't mean for this to sound flamey, I just think that several of your observations are wrong/skewed and felt I had to speak up :)

I do, but the big downside to them is the insane licensing costs associated with the current offerings.

It's free, and the definitions are often (not always, though) kept more up-to-date than McAfee and others.
