Spam Quarantined mail can be used as Spamassassin ham?

[Nikolaos Milas]

Hello,

I am storing spam (from Amavis) to:

    $QUARANTINEDIR = '/var/blockedmail'

i.e. to '/var/blockedmail/spam/' as:

    $spam_quarantine_method = "local:spam/%n-%m" ;

Question: Can I use stored spam files (e.g. "02792-01-bzM11CH7LOH8") as 
they are (i.e. without any modification/conversion) to train 
spamassassin for ham (of course when spam is not real spam)? That is, 
can I simply move/copy such files in a "ham" directory and then train 
spamassassin? Will SpamAssassin recognize these files as spam email 
messages?

Please clarify.

Thanks,
Nick
