Hi. Setting up one of our Categories to allow anon users to email into the category. (We have a contact form that sends the output to the Category email address)
On Category settings we had toggled this on
Accept emails from anonymous users with no accounts
I noticed that if the User had signed up, but not activated their email Discourse would not allow their email to be sent into the Category.
It would allow a totally anon user to send an email (It sets up a user name which is ghosted out on the admin screen)
