Hi, my boss just bought a company and she managed something so all the emails meant to arrive in their email box is fowarded to our. A client of the previous business emailed them and it was fowarded here, but as if it was from them. I can't find the origninal sender and answer them. (no, they did not leave any information to contact them) I clicked the little pointing down arrow to see if I could find something, but it was mostly server information and the thing that checks if it's spam. I have general knowledge in such thing.
thank you for a feedback x and sorry for poor english, not my mother language
If there isn't an email in the message header that is from the actual client then most likely the server that is forwarding it stripped it out.
