Hello,
I have configured my incoming & outcoming mails server in odoo, everything is set properly, I can send mails to different users, but I have a problem with receiving, when I try to send a mail from gmail to the email configured in the incoming mail server, I got this error :
Delivery to the following recipient failed permanently:
xxx@mydomain.com
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomain.com by mydomain.com. [my server IP].
The error that the other server returned was:
550 5.7.1 <xxx@mydomain.com>... Relaying denied
