Spamassasin auto-learning

[Nicolas Viers - SCI]

                                 Hi,
i use MS+SA with bayes enable.
I use too spamlearn script (in attach) to force SA auto-learning.
But i receive the same message more than one time before "spamlearn" 
without filtering
by SA.
Is it the only thing to force SA to learn spam message  or not ?

Thanks a lot

# This script takes a mail file full of SPAM and sa-learns it for you.

# script splits the mails in the mail file apart, runs them thru
# spamassassin -d to remove the markup, and feeds them to sa-learn.

# Specify the file on the command line, or change it here:
# this is the file with the spam you need to sa-learn
spamfile='/var/spool/mail/spam'
