Default mail folders after installing Roundcube

Hi everyone.

I’ve just set up Yunohost on a fresh debian, and installed Roundcube.

After login with my newly created user on it, I can see that the regular defaults folder that I expected are not there (Sent, Trash, Draft, Junk).
After sending a mail, the Sent folder was created. But when trying to delete amil, it fails as it can’t find the Trash folder.

I was wondering if it was the default behaviour or not?
It seems a bit cumbersome to ask my non-tech savvy users to create those default folders.

Thanks for your help!

I did like you said: I created the folders manually!
