How do I mark spam and keep it unread?

[webmail-user]

When I select a new email in my Inbox and mark it as spam it is moved to the Spam Detector folder but it is now considered read. Is there a way to mark it as spam without it being considered read? Thank you.

You can remark it as unread, but it really isn't necessary.  Read/unread is only a flag for your benefit.
