I am trying to configure Zoho Mail SMTP in Odoo 18 (Windows 11, local installation) but Odoo fails to send emails even though “Test Connection” is successful.
SMTP settings used:
SMTP Server: smtppro.zoho.in
Port: 465
Encryption: SSL/TLS
Username: full Zoho email
Password: app password
Outgoing email domain: configured
Odoo shows Test Connection: SUCCESS, but when I try to send an actual email (quotation, reset password, etc.) I get:
SMTPServerDisconnected: please run connect() first
What I need help with
What are the correct SMTP settings for Zoho Mail + Odoo 18?
Is there any additional configuration required (SPF, DKIM, ports, app password)?
Why does the Test Connection succeed but real email sending fails?
Does Zoho require a different hostname for SMTP from local servers?
If anyone is using Zoho Mail successfully with Odoo 18, please share the correct working configuration.
Thanks!
