Is there anywhere to mark email as Spam? None of my spam is going to the spam folder.

By default, Roundcube has a Junk folder instead of Spam. If you move an email to Junk, It’s the same as if you were to move it to Spam on the previous AtMail system.To change the folder name to Spam, you can go to settings > preferences > special folders > enable “Show real names for special folders”
