help in identifying email headers

A user received an email with a threat.  I looked at the headers on the original email, but I'm a little puzzled as who the sender is.
Can anyone help me figure out the sending ISP or domain name?
As it looks like the sender is from, which I changed from my actual domain name, but how would that be possible?

someone spoofed your via a script etc, you can in theory send from any address but depending on what hops it goes through then it may or may not be recieved in this case it was

the sending address is

which you can see from those links where it was generated from
DanNetwork EngineerAuthor Commented:
So is a godaddy IP address, so that doesn't help me much.
Actually, in the real email, it did list my actual domain name, I just changed it before posting the post, just so I don't disclose my actual domain name.   So whoever it was, they are from Arizona, according to, right?
Daryl GawnSystem AdministratorCommented:
yes sorry i re-read your post then edited mine.... yeah thats where they sent it from, could have been anywhere in the world themselves.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Daryl GawnSystem AdministratorCommented:
most decent SPF - antispoof gateways should stop or at least quarantine these types of emails. You can't control people outside spoofing your domain name unfortunately but you can at least stop or hold them up from being sent to your own company etc.
DanNetwork EngineerAuthor Commented:
What's strange is that sending email used was an email inside my organization that is disabled.
So how can I stop this from happening?
I think I only have relaying enabled inside my organization.  Are there any specific configuration I need to check in my exchange account?
Daryl GawnSystem AdministratorCommented:
you can only stop it coming into your organization if you have a antispam/antispoof etc gateway that does various checks etc.

if you dont exchange will just receive it and deliver it if its addresses to a valid email address inside your org

If you don't want to post the ACTUAL header, I would suggest you run it through analyzers yourself -

So I used and it says that most likely the email came from IP:
