Adding Return-Path header is not effect

[abilican]

Hello;

Thank you for this awesome package, I am using it with pleasure. But I have an issue and I have a problem with Return-Path.
I want to add custom Return-Path header using SetReturnPath function. When I examine the sent email headers, I see that it is not working. It is the same with From address. I tried to add using AddHeader func but it is blocked for Return-Path. How do you use returnPath local variable? I examined the code and I've never seen it used.
Could you please advise me on how to solve the issue?

@abilican I was able to bypass this issue using SendEnvelopeFrom instead of Send

email.SendEnvelopeFrom(mailerConfig.ReturnPath, client)
