I'm trying to config spam to:
1. Deliver the mail to user, with spam header and to the '.Junk/new' dir.
2. To store a copy of the mail to the quarantine local dir: '/var/spool/amavisd/quarantine'
3. In my tests, I've seen that postmaster gets a notification mail for each spam message. Is this able to be configured to: a) doesn't send that messages to post master, or b) keep this behavior (keep sending these messages to postmaster)?

Number 1, works OK
Number 2, does not work. No files added to quarantine dir structure: '/var/spool/amavisd/quarantine'

I've tries with this amavisd configs:
A) $final_spam_destiny = D_DISCARD/D_PASS;
    $spam_quarantine_method = 'local:';
    $spam_quarantine_to = 'spam-quarantine';

B) $final_spam_destiny = D_PASS/D_DISCARD;
    $spam_quarantine_method = 'local:spam/%Y-%m-%d/%m.eml';
    $spam_quarantine_to = undef;

C) $final_spam_destiny = D_PASS;
    $spam_quarantine_method = 'local:spam/%Y-%m-%d/%m.eml';
    #$spam_quarantine_to = undef;

Can anyone comment about the right config?

Thank you in advance,
