Hello,
I'm with the Odoo version 9 community and I'm having problems sending emails, I get the following error:
Fallo de entrega de correo
La entrega de correo falló vía el servidor SMTP 'mail.domain.com'.
SMTPRecipientsRefused: {'nnnnn@domain.com': (550, 'Verification failed for <nnnnn-5-crm.claim-5@domain.com>\nNo Such User Here"\nSender verify failed')}
The SMTP server is configured correctly and the test connection button gives me OK.
The email address indicated in the error message obviously does not exist, the correct one is nnnnn@domain.com.
I imagine that something is missing at the SMTP server level, I have looked everywhere and I cannot find the solution.
Thank you very much
Greetings
