It appears this plugin has a hard requirement for username/password authentication (since SMTPAuth is explicitly to true) but this may not work in all situations.
It would be better if this was an option, since there may be mail relays who employ other means of validating access (e.g. IP whitelists) and wouldn't work with SMTP Auth.
