My regular email account is through AT&T. So I go to the mail site, click on "preferences," then on "spam," and in that window I can copy/paste email addresses that come to me that are spam. This a.m. I was going to do just that with one I received that said I had 6 messages waiting for me from this online dating service (that I don't subscribe to). However, the "from" address for this spam email was my very own address!!! How can that be?
