MailNotes - have I gone totally mad ?
 

I am fairly confident that I did not create a new email folder that recently appeared called 'MailNotes",
but there it is, sitting under the Inbox.

I access FastMail on a desktop PC using the internet version (i.e. I don't use an email client).
(All the email is also forwarded to the FM web app on an Android device)

The MailNotes folder has six totally random emails in it, all from 2017.

What's going on? Am I going crazy???
