Odoo Outgoing Email Error - Sender Verify Failed

If you are getting the following error when sending out the email, you've come to a right place.

Unknown error: Mail Delivery Failed Mail delivery failed via SMTP server 'None'. SMTPRecipientsRefused: {'xxxx@gmail.com': (550, b'Verification failed for <bounce+126-sale.order-13@xxxxx.com>\nNo Such User Here"\nSender verify failed')}


a) Delete mail.bounce.alias in the system parameter (Technical). Therefore, Odoo will be sending with postmaster-odoo@domain.com.

b) Create a new email postmaster-odoo@domain.com.
