Since you neglected to say what version of Windows you're using, I can't give you specific directions. I can tell you that setting up message rules is the answer to what you want to do.
I've tried to block a domain recently, but mail from that domain keeps coming. Any way to make it go to the junk file?
One e-mail keeps coming concerning a listing I made on Craig's List. How they got my e-mail from the posting, I don't know. Each one is a sexy come-on, and comes with a different name, but all from yahoo.com. I don't want to block yahoo since I get mail from other addees through that domain. Any other way to stop this other than just dleeting them individually as they come into the Inbox?
