Julian,

Thanks. 

I'm aware that KAM and MS are two separate things and related to SA instead of
MS. I only mentioned my experiences to help others if they are running KAM with
any distro and MS. There have been a lot of posts lately about SA timeouts, so I
thought this might be helpful. 

I'm sort of stuck for a while with the old distro. We don't have a lot of spare
servers with this type of power for me to upgrade with. And this server is an
email do-all, running MS, SA, ClamD and the mail store for two domains.

Even with the old OS, I give you kudos for your software as it still does what
it's supposed to do. It'd probably do better with all the newer modules, but
alas - the money issues here at our company. 

I hope you realize that this is praise, and not to be taken as argumentative.
This mail list is the central focus point for many different pieces of software,
as your software ties many of those pieces of software together. The list is
comprised of many intelligent people who offer their wisdom. I can't usually
offer much of it, so when I do have something to offer, I try and pay my dues.
It's probably not the way it should be, but it is the focus point.
