I would like to know if every of the test listed in http://eu.spamassassin.org/tests.html is run or if i have manually to enable all test in my local.cf site-wide configuration file.
That's a list of the default rules...
All of them are run, however, a few of them may be disabled depending on what's installed on your system.
DCC_CHECK - requires dcc to be installed
RAZOR* - requires razor to be installed
PYZOR* - requires pyzorRCVD_IN_* requries the perl module Net::DNS to be installed
BAYES_* requires that bayes be enabled in your configuration AND a sufficient amount of spam/ham be trained through the sa-learn tool.
I also would like to know, if i use the autolearn feature, how can correctly send a message from OutLook Express preserving the oringinal headers.
I know NOTHING about OE, however, many have suggested the "resend" feature works

Also, you appear to be confusing "autolearn" with non-automatic bayes learning.
Autolearn is just that.. automatic.. you don't do anything at all, sa decides for itself if it should learn the message as they come in. You don't resend, redirect, or anything else for autolearning to occur.
Manual learning (ie: setting up a script to feed messages to sa-learn) is when you might need to resend a message.
