I am using a filter to prevent mails from getting moved to the spam folder, because I want to see them.
As a consequence some mails are correctly prefaced with:
This message was not sent to Spam because of a filter you created.
So far so good. Now, I would like to mass review all these messages that would have been moved to the spam folder and that show this notice when opened. Is it possible to find them all and how?
I have now modified my filter to add a custom label to future mails, but how can I target the messages already in my inbox?
I would also be fine with a Google Apps Script solution or similarly nerdy, but I cannot see a way to identify these messages: https://developers.google.com/apps-script/reference/gmail/gmail-message
Thanks
