Limitations of Spam Training folder

Idea shared by Douglas Foster - 4/17/2025 at 7:48 AM

Under Consideration

It appears that messages arrive in the Training folder as possible spam in one of two ways:
(a) manually placed in the users Junk/Spam folder
(b) automatically placed in the user's Junk/Spam folder by the Outlook program's undocumented spam-filtering heuristic.
(c) manually-created rules configured in webmail or Outlook

When processing these files, the evaluator needs to consider:
(a) is this message objectionable to this user or all users?
(b) is this message a legitimate news feed to which the user previously subscribed, but now he is using the spam folder instead of the unsubscribe link?
(c) Is this an automated heuristic that fired incorrectly?
(d) or is this actually spam that needs to be blocked.

When the message is dropped in the spam Training folder, all I see is the EML file with a random file name. It would be useful to know which user put it there and whether it arrived from a manual decision or an automated decision.

Any hope of creating a metadata file to help interpret the significance of the spam complaint?
