No problem. We understand you. If you have issues with English then write in
German (some of us will understand you). But if you can please continue in
English.

See README in the root directory of the source, chapter "2.5 DSPAM USER
PREFERENCES" . This is a short abstract of the preference for creating corpi:
------
makeCorpus { on | off }
When activated, a maildir-style corpus is maintained in the user's data
directory (DSPAM_HOME/DATA/USERNAME), suitable for future retraining or
other analysis. (default:off)

Yes. You could misuse that functionality as a sort of backup.

No. You can't create a corpus from a old installation. Enabling "makeCorpus"
has only a effect of new arrived mails after you activate that preference. Old
mails which are already delivered will not be affected by that option.

If I understand that right you are asking if you could shorten the training for
the new installation by using old data. Right? Yes! You can do that. You could
dump or copy the old data and import it on the new installation. But if I see
that right then you are planing to change the tokenizer and changing tokenizer
mostly means that old data is useless.
3 years of data is all fine and okay but to be honest you will not loose much.
Just the first days will lead to more training but after a short time DSPAM
will catch up and be very accurate.

Not really.

If you have many users then using groups could help to shorten training time.
