Mail landing strait in the waste bin

Hi there!
Now I realised why my certain mails landing in the waste bin.
My critical mails are comming from the community of my friends,what is at the Google server goes to the “forum” subfolder,but this kind of subfolder is not exist in the eM Client originaly.
During syncronisation all the mail from there,rather choose the way to the waste bin.
How would be possible to setup a new subfolder in eM Client to synchronise accordingly?
Am I clear?
