Templates

For each letter sent to odoo there is a template in which you can add dynamic elements.
1. Go to Developer mode
2. We are looking for templates with the Auth Signup prefix:

Error reason

"SMTPRecipientsRefused {'info @ email': (501, b'sender address must match authenticated user ')}"
Error "SMTPRecipientsRefused {'info @ email': (501, b'sender address must match authenticated user ')}"
occurs because of the default mail settings. Odoo creates a special mailbox for the object in Odoo.
For example:
mailbox bounce+80-res.users-13@granucci.ru will be created for user with ID 13
When sending letters to this box, incoming messages will be automatically “Attached” to the user with the specified ID
in the headers of the letter goes
mail FROM: <bounce+80-res.users-13@granucci.ru> size = 11497 \ r \ n '
what's not to like is authorization relay
in consequence of which an error occurs.
Odoo requires special configuration of mail servers for incoming / outgoing mail

Bugfix

The following settings must be made for the 3 templates.
