Description

Adds a new SMTP_NOAUTH environment variable (boolean, defaults to false) that allows disabling SMTP authentication when connecting to mail servers that don't require credentials, such as those using IP whitelisting. (let me know if you prefer to just check if user and pass are empty and avoid an env variable)

When set to true, the nodemailer transport's auth object is set to undefined, skipping the authentication step entirely.

This avoids connection errors that occur when nodemailer attempts to authenticate against servers that have no auth mechanism configured.
