Odoo 17: Mail Server Error — SMTPAuthenticationError when sending automated emails

Question

Hi community,
I’m experiencing an issue with sending emails in Odoo 17. Whenever Odoo tries to send automated emails (like invoices or notifications), the sending fails and I see this server error in the logs:
smtplib.SMTPAuthenticationError: (535, b'5.7.8 Authentication failed')
