PopMonger is a free but elegant tool to help you with mailing list management. This very small program is easy to set up with any POP3, IMAP, or Microsoft Exchange Server mailbox, and runs in the background. It can check multiple mailboxes and parses through messages, looking for delivery failures, subscribe requests, and unsubscribe requests. When PopMonger finds a matching message, it can add the sender's address to a list along with a date and a label indicating why the email was added for auditing purposes. You can optionally mark a message for deletion after processing, and leave unmatched email in your mailbox to check personally. As part of the free Mach5 Mailer suite, it can reply to the message with text from a file or redirect the message to another mailbox. With Mailer Gold, it can also parse the incoming email for fields you define, and provide complete information about the inbound message to your VBScript, JScript, or PHP program, giving you complete database integration with inbound email. Mach5 PopMonger is Free. Mail sending capability requires Mach5 Mailer Free. Scripting requires a Mailer Gold license. Requires Windows 98 or later. AdWare and SpyWare Free.
