I'm trying to figure out how an email arrived in my inbox today. I knew the sender, and it was a legitimate message, not spam, sent to a group of people.

The thing is, my email address wasn't anywhere on the address list. Usually my email program (I have AOL) states something like, "This message was sent to you and 5 others..." and shows my address first. This message just showed To: (2 email names) and CC: (3 email names), none of them mine. All my other messages show my email name in the To: line.

So, if my email address wasn't in this message, how did this get to me?
