Error send email - Sender mismatch


i’m trying to receive a mail from my ghost instance but i have this error :

Failed to send email. Reason: Message failed: 550 5.7.1 Sender mismatch.

I’m using docker with this email parameter :

      - mail__options__auth__pass=mypassword
      - mail__options__auth__user=myuser
      - mail__options__port=465
      - mail__options__secure=true
      - mail__transport=SMTP
