Spam Corral

Spam Corral
The sendmail virus/spam filter (Spam Assassin) redirects all received spam to the spam corral, instead of delivering it. However, it is possible that a piece of spam could be valuable or even that a non-spam message be misidentified as spam and corralled by mistake. The spam handling programs in this package make dealing with spam simple and easy.
The notification program is run once a day by a cron job, whereupon it will send email notification messages to all recipeints of spam, summarizing each of the messages received since the last time it was run. When a user receives notification, they can optionally reply to the message, listing any pieces of spam which they wish to see and it will be remailed to them (this time it passes through the filter unscathed).
