Be careful about doing this. Things that you forward to spam@domain.com
will appear to come from your address, so you may accidentally teach
SpamAssassin to negatively score messages from your domain.
A better solution is to export a maildir as a shared IMAP folder, and
then drag-and-drop spams there with your mail reader. The spam will not
be changed by another run through the MTA, which will improve the
effectiveness of sa-learn.
You could then run a cron job against that maildir like this:
IFS='
' for i in $(find /my/spam/maildir -type f)
do
sa-learn --spam "$i" && rm "$i"
done
