How to move to trash folder automatically?

The log revealed 2 spam messages and moved them, the 40+ spam messages were in the Junk folder with no mention in SpamSieve’s log.

In other words, the 40+ spam emails appeared to have been filtered before SpamSieve could filter them. [They were in the Junk folder, and I manually trained them as spam - which moved them to the Trash folder.]

I just want the spam to go to the trash folder automatically.
