The lack of a spam folder is one of the problems with such a
solution. Having a middle ground quarantine is actually quite nice.
However, the biggest problem is these solutions are global in nature.
We let individual customers considerable control over the process.
They can each set their own block and quarantine levels, configure
their own white and blacklists and even turn the spam controls
completely off. For various reasons none of that would be possible
with this solution and all the implementations you link to all run
with a single global configuration.
