Phishing actually from apparent sender's domain

Hi, Experts.  I've been seeing something new in the world of phishing emails (at least, to me).  The email comes from "" -- and the routing headers bear out that this email actually came from ""  I am used to seeing a spoofed address and routing from obscure servers that bear no relation to that domain.

Is this a new kind of spoof?  Are they actually spoofing routing? Or am I seeing the work of a botnet of some kind? Should I be alerting the sending domains?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Just like you I have never encountered spoofed routing.  If x-originating-ip in message headers matches the IP of, then it is really hacked and it'd be good to notify domain administration of that. Full message headers would allow to check this in more detail.

Right, that's what I was looking at.  And they are coming from the domain of the apparent sender's address.  It's a new twist for me.  Botnet, maybe?
