A place to ask questions, connect with others, and stay in the know
I found a solution to my issue.
I use in forward bloc a "redirect" method. So the "from" field are the original sender.
However, in my case, my custumer used a "EWS" protocol to connect to the mailbox. And this protocol forbiden an out email with an another identity. So we have changed the SMTP parameters to send out email by SMTP protocol and not by EWS.
Since this modification, we don't have any issue.
