This is spamcruncher.

Welcome to spamcruncher.

Do you know that situation: You open your email-account and 22 messages are waiting for you? Then you open your inbox and realize, that 22 of 22 messages are spam and your email-provider doesn't give you anti-spam-software for free?

With spamcruncher you can easily purge your POP3 or IMAP-mailaccount of spam with one of the best spam-detection-engines available: SpamAssassin. SpamCruncher is a small perl-script, that makes it easy for you to scan, save, delete or move spam-messages in your remote mailboxes.

And the best: SpamCruncher is released under the GPL, so you can download it, modify and redistribute it freely (as long as you stick to the GPL, that is :-) )
