If you want to disable TLS, you need to uncomment this line, and set it to `false`:

```
#DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)

```

However, there’s no relationship between POODLE and newer TLS protocol versions, nor is there any relationship between SMTP and POP3. Mailgun _does_ support TLS on SMTP connections, they just don’t support it correctly.
