From the developer:
PopMonger steps through the email in a POP, IMAP, or MAPI email account, matching each email against a set of rules, and then applies a set of actions. It's quite powerful, and has a number of handy uses. PopMonger doesn't even have any annoying ads or anything. It just pops up a dialog box when it starts that lets you know it's part of the Mach5 Mailer suite of tools. It works with XP and above, and is very small and simple to run.
