Email Not Sending in Self-Hosted Typebot using Zoho SMTP

I'm self-hosting Typebot using Docker and trying to configure SMTP with Zoho. Even though SMTP config seems correct and Zoho is reachable, no emails are being sent (no success or error logs either).

How to reproduce it
Set up Typebot using Docker with the following SMTP environment in typebot-builder:

SMTP_USERNAME=lakshminarayanan@youthdreamersfoundation.org
SMTP_PASSWORD=my-passwd
SMTP_HOST=smtp.zoho.com
SMTP_PORT=587
SMTP_SECURE=false
NEXT_PUBLIC_SMTP_FROM="YDF Notifications <lakshminarayanan@youthdreamersfoundation.org>"
NEXTAUTH_URL=https://scholarsaathi-builder.ydfindia.org

What I expected
The test email to be sent from Typebot using Zoho SMTP.

At least some log output in typebot-builder container (success or failure)

Extra Info:
Typebot version: baptistearno/typebot-builder:latest

Hosted on: Ubuntu 22.04 VPS

Verified Zoho SMTP via telnet

SMTP credentials and domain verified (SPF/DKIM)

Tried enabling/disabling SMTP_SECURE, confirmed correct port


Open questions
Is Zoho SMTP compatible with Typebot’s setup?

Am I missing any required environment variables?

How can I enable debug logs for SMTP in Typebot?

Does typebot-viewer also require SMTP config?
