Authentication Inquiry

Okay friends...please help me understand something about email authentication here

So we have Interspire set up on our server to send emails. The primary domain (and the only one) hosted on that server is, let's say, example.org. The SPF and DKIM records have been published accordingly

Now while testing our email delivery, I used name@example.com as the from address, please note that this domain is NOT hosted on the same server as example.org

The email was delivered with the following as the from address

name@example.com via example.org

..and in gmail is showed

mailed-by: example.org
signed-by: example.org

now my question is - is this an acceptable form of sending emails? Doesn't this fail authentication since the sending domain (example.com) is NOT hosted on this server?

Shouldn't the from address be name@example.org instead?

Please advise

Thanks a lot!

anyone?

When you say "from address", do you mean the envelope "MAIL FROM:" or the "From:" address in the body of the message. Some receivers such as Google will treat your messages differently depending on whether or not the 2 are aligned (DMARC).
