Hi Blobbi,
found half solution
so, when the spamassinator found a spam, take the original email and put them in attachment, and create a email for sent at the email destinator (if you have setting the bounce mode, for the spam.
The file, in endian fw, not exist in italian language.
the path is: /usr/share/spamassassin/
inside this folder can to found many *.cf file.
the language traslation for me is 30_text_it.cf
i've found a file, just compiled in italian at this address:
http://spamassassin.apache.org/full/2.6x/dist/rules/30_text_it.cfjust to download or copy and pasty in you file.
this file are avalible in: de,fr,it,pl and nl.
for the english version, the file, every in this folder, is 10_misc.cf.
Now, i can receive the email of spam detection in italin, but for half.
infact at the end continue to report a part in english. this part it is only present in the 10_misc.cf file. But if i try to rewrite in italina, for example, the file continue to incoming in englis (final part).
If you found a solution for this problem, whe have found the complete solution for customize the email spam detection.
bye
