I was just curious wat those spamhandler packages do, how they are configured and how they interact with the mail server.

There is spamhandler-spamassasin and spamhander-default. Which one should I use for a single-context setup?

Since up to now, i'm having amavisd-new/spamassassin tag spam and sieve sorting it into subfolders with no user interaction at all.

Is there documentation for those spamhandler packages? I couldn't find any (maybe I have to look harder).

Tanks in advance
