Hello
All reply mails from my customers failed in odoo. I can see them in Technical>E-mails.
The error message :
Échec d'envoi de l'e-mail
Échec de l'envoi de l'e-mail via le serveur SMTP 'None'.
SMTPDataError: (550, b'5.7.1 Sender mismatch')
I created all alias email in my provider and set them in outgoing/incoming server.
Might be something i forgot.
Thank you
