[Users] Can't figure out how to make a filter

[John Jason Jordan]

Claws Mail 3.8.1 on Xubuntu 13.10.

I have a Facebook account that I would love to delete, but I need it.
Several times a day I get a message "John, you have notifications
pending," which I find very annoying. The notifications are just trash
that I have no interest in. 

I am trying to create a filter rule based on the above subject that
would automatically delete these e-mails, but no matter how I
configure it, it doesn't work. How can I configure Claws Mail so I
never see these messages?
