Yes, `cloudflared` can be configured to tunnel traffic on non-standard ports. When setting up the `config.yml` file for your tunnel, you can specify the `service` to listen on any port your SMTP server is configured to use, such as a custom port if you're running multiple services or for specific security policies.
