Could you build this?
Partial The local ML classification logic is straightforward, but integrating custom spam filtering into Apple Mail on modern macOS requires developing a native MailKit extension, navigating App Sandbox limits, and obtaining Apple developer entitlements.
What it would actually take: The app requires a native Swift macOS wrapper using Apple's MailKit framework (specifically MEContentFilter and MEMessageActionHandler protocols) coupled with a local on-device classification model (such as CoreML or Naive Bayes/fastText). The primary obstacle is dealing with strict App Sandbox restrictions, managing MailKit lifecycle constraints, and handling security entitlements for Apple Mail extension deployment.
