Email headers show generic ip address

[pip]

I have set up a domain with an email account. Email works - I can send and receive. I sent an email to my gmail account and checked the headers. There is information about the domain I am sending from that is missing and in place of it is the ip address of my server as well as the user name I use to log in to Vesta (admin) and what I named the server when I created it. Vesta is running on a cloud VPS. node is what I named the server when I created it and that's included in the email headers. Don't know if/how that is relevant or where that information is even stored.

I don't know where to start looking to fix this. Hoping someone can help.

Thanks!

This is the message when I select Show Original in gmail. I've put in bold the references to the ip address of the server as well as my login username.

The "Received:" header is set by the gmail server. You can't modify it. The username is set by exim on your server to track the source. If you will receive (I hope you not) an abuse from ISP you will be able to tell who was hacked or who is a bad guy and suspend that account.
