If you have "maildir" mailboxes, running _spamassassin -r_ multiple times can be tedious for large numbers of spam. So you can use this \["report_spam.pl"\] script to run it for you. The script is written in perl. You can save the script to your spamassassin computer and then run it using _report_spam.pl your_spam_directory_. Each message in your_spam_directory will then be learned in bayes *and* reported to the checksum services.
