I have OL 2007 in a POP3 configuration.
I have thousands of "junk" email and I have created a list of "spammers"
that total about 400 email addresses. I have imported these into the Junk
Blocked senders list. This will be great for future emails.

The question is, is there a way that I can force the processing of the junk
blocked senders on email already in my inbox?

Or...Should I create a RULE with these addresses? Is there a way to add
hundreds of email addresses to a rule?

Thanks
