Mail delivery failed: returning message to sender whmcs

[filetobackup]

Hi there, I know there are tons of emails with this type of error, but I have tried all the solutions described there and I still can get rid of the email auto responder to the sender with an error declaration.

The thing is that the ticked it is opened ok, So I don't want to send that auto responder to the email sender.

I just updated to whmcs 6.0 issue happened after the update.
