Your logic is flawed although I understand your motivations.  When it  
comes to security software (which I put MS/ClamAV etc into) you MUST  
stay up-to-date or the bad guys win by default; as in the defender  
doesn't show up for the prize fight.

Have a read on Debian's packaging system.  You can actually add the  
testing/unstable repositories to your /etc/apt/sources.list (or /etc/ 
apt/sources.list.d/<repo_stub>) and then use /etc/apt/apt.conf to only  
pull specific packages from the unstable/testing repo's.   
Alternatively, you could forget Debian's SpamAssassing/ClamAV/ 
MailScanner packages and simply install from Julian's installer.  This  
last approach is the one I have adopted and it has *never* caused any  

Here's my /etc/apt/apt.conf on a production machine:
$cat apt.conf
APT::Default-Release "stable";
APT::Cache-Limit "16777216";
Acquire::http::Proxy "";

Notice the "Default-Release" option?  That means "apt" will only pull  
in a testing/unstable package if I tell it to like this:
# apt-get -t testing install <package_from_testing>


When you add stable/test/unstable all to the same apt configuration,  
you may get errors when updating the package list due to memory  
exhaustion.  That's why the "Cache-Limit" is set to a larger value in  
my config.  The proxy line means that after the first machine has  
updated itself, the remainder get the packages from the proxy which is  
faster and friendlier to the mirror operators :)  Just have to make  
sure your repository and proxy config are consistent accross your  
machines and it works like a charm!

Consider your customers, the rest of us netizens, and get your  
software updated :)  Julian is a top guy and is passionate about his  
software, but he does provide his time and software for FREE.  He  
can't be expected to support all versions of MS for all time, for  
free.  Have some consideration ;)
