Detecting spam
Generally speaking I am familiar with and can recognize email messages that are spam, aka junk mail. However, occasionally, like now, I have received an email from a sender I do not recognize. But, I have contacted a vendor and my bank regarding an issue I'm having with this particular vendor. (not Apple) Thus I might be getting a response from an individual at said vendor. Since I only see a sender's name in my Inbox and not the complete address, is there a way in which I can determine if this is spam without opening the email? Or perhaps there is a different way to display messages in my Inbox that I do not use but could switch to, at least temporarily?
Thanks if anyone out there can shed some light on this pesky issue.
I am using Mtn Lion, OS 10.8.5 (Yes, I know I need to upgrade.)
Mail v6.6
Safari 6.2.3
Desktop is a mid-2011 model
AT&T is my ISP which means that email is 'routed' through Yahoo to MacMail (I hope that's at least close enough in terminology to be understood.)
