Routing messages with Procmail
Depending on your preferences, tagging messages as spam may not be enough. Maybe you'll want to set up a rule in your e-mail client that moves any unwanted messages from your inbox to a dedicated spam directory. Or maybe you want such routing to happen automatically on the server. We can configure this using Procmail, a mail filtering and delivery agent.
In this recipe, we'll look at how to configure Procmail to route messages. We'll scan incoming mail, looking for a special header that SpamAssassin adds to messages if it thinks they're spam and then deliver them to a separate directory instead of the inbox.
