Inbox Failure notice not mine

I got a postmaster failure notice on an email I didn't send. My email address is "txxx.xxxxxs@yahoo.com" (there is no "ar" on my email address). I'm trying to figure out if my computer is infected and some Ruski is trying to use my account or was if this message was a just ploy for me to open. I ran through all the steps in the Malware_Cleaning_Guide. Everything proved negative, however I cannot adequately read the Hijack-This log (shall I it send it?). The message was:

So I did click to open. But...that doesn't really do anything if it's just a phishing scheme though they do now have a live one on the books. Right?
