Kerio 4.2.0 Beta 3 stable?

Just a quick question - has anyone been using the Kerio 4.2.0 betas?
I'm downloading Beta 3 right now, but I just wanted to make sure there are no serious issues before I install it.

Cheers. :)

what's the beta got that the official doesn't that makes you want to try it?

a firewall is implemented in IRQL 2 code, (above all thread priorities), not something you should really beta I don't think.
Haven't looked into it, but I haven't used Kerio for a while (have been using Windows Firewall) so I just thought I'd get the latest available build.

Are you using the latest release version?

4.1.2, I love it.

but what I love is the sandbox, which most people find annoying...I don't think you even need an antivirus if you're running a competant sandbox, and this is the most competant I've ever seen
Just downloaded 4.1.2 now. I agree with you - I like the sandboxing in Kerio as well.
Time to get this installed. Thanks perris. :)

whatever happens on the computer needs your permission or rule.

for instance, if you launch mailwasher, the sandbox will tell you explorer is trying to launch it...you then create a permanent rule to allow.

then the sandbox will tell you mailwasher is trying to access the internet, and then the internet to access mailwasher.

then the sandbox is going to tell you mailwasher is trying to launch your mail client.

nothing should happen on your computer till you individually allow it, or you create a permanent rule to allow it.

this becomes anoying at times, especially installing programs, but you can always dissable the firewall when you know a bunch of things are about to happen that would need permision.

for instance, windows updates are a real pain in the butt going through a sandbox.

but man, do you feel secure


Cool, thanks for the explanation. I just installed it, will give it a whirl for a while.

Hmm, I don't really see an easy way to manually add applications to the Application list, kind of annoying if I have to play a game and connect to a server then wait for Kerio to popup in order for me to create a rule...
Or I'm blind (I'm really tired though eheh)

you can also temporarily disable system security (but not internet security) if you need to, which will still give you the same security as a normal firewall
