inhouse-tool/ChkMails ? reverse-engineered prompt

Build me a small Windows desktop app that sits in the system tray and checks my mail account for new messages, then quietly tells me when something arrives.

I want it to connect to POP3 or POP3S accounts, let me register more than one mailbox, and save the account info securely. It should have simple dialogs for account setup and for defining what kinds of messages I do not want, based on things like sender, domain, subject words, recipient, encoding, time zone, and authentication results from the mail headers.

If a message matches my unwanted rules, the app should delete it automatically instead of moving it to a folder. If mail is fine, it should stay silent unless there is new mail. Please also keep a small log so I can review what happened, and let me reopen the settings from the tray icon. It should feel like a lightweight Windows utility, not a big email client. If you need to, look up current docs online for any Windows or POP details.
