Hello,
I have a booking system in Odoo 10 that should be sending emails for the clients but they are not leaving from Odoo. If I go to General Settings and there into the queue of "Failed emails", I can "Retry" and then "Send" and then it leaves and arrives to the client normally. But no message goes without failing first.
We had the main admin email ending with different domain than the domain alias, so we tried if changing that would change the matter but it made no difference either.
We are getting an Failure Reason like
The action could not be performed due to security restrictions. Please contact the administration.
Hi are you retrying the send mails using the same user with who is supposed to send the mail?
The error says the user don't have access to read message, sending mails is related with discuss module
