let’s see if i can blog

As you may not be aware, i am currently suffering from a headache, a skull breaking one. With nothing to do, or should i say, too much thinking makes my head hurt and decided not to do anything, i just scanned my mails and see if there are things left undone. What reminded me is this message i received couple of days ago. I got a little worried because i don’t know what this means. Is someone using my domain name and sends spam? Am i not alone?

Can someone explain these things to me please…
