Look at Tools>Message Rules>Mail>New... bar. Study the dialog box; it's
fairly straightforward. I checkmarked, "Where the subject line contains
specific words". Then in next section, I selected "Delete from server".
The next time a message comes with the word, it's deleted from your server
and you don't have to deal with it. Add rules as new unwanted mail arrives.
Don't forget to apply the new rule before closing or it won't go into
effect. You will have to create a rule for EACH word and wanted mail with
it will be deleted also, unfortunately.
