Process to get rid of a mail message.
On my iMac I have a message on my Apple email that has (No Sender) where the name of the origin of the email appears. I can't get rid of it. I tried moving it to Junk, Trash, and even to Priceline based on the actual content - all to no avail. My question is simple - how do I get rid of a mail message with (No Sender)?
