[Mimedefang] training spamassassin

[Saisab Pradhan]

Hi,

I have successfully installed mimedefang 2.52 / spamassassin 3.0.4 / 
sendmail in solaris 8.0 to filter spam mails with the following rules

1. hits >= 10 , mails are discarded silently and are quarantined.
2. hits >= 6 , mails are forwarded to a separate mail box which is read 
regularly and if false positive, are redirected to the original recipients.
3. hits >=5, spamassassin report is attached to the email and is sent to 
the recipient.

Now, some of spam mails (in fact, the numbers are quite high) are still 
getting past the spamassassin filter. I have created a mailbox where the 
users can redirect such false negative emails. when I do
sa-learn --spam mailbox, it returns
" Learned from 0 message(s) (1 message(s) examined)"
where as the mailbox has around 100 redirected spam mails. Is that the 
right way to do it or is there anything else I can do to train spamassassin 
manually? Please help..

Thanks for your help,
