- If `SMTP_ADDRESS` is set, configure Action Mailer to use it, along with additional optional SMTP-related settings. - Otherwise, don't set config (for compatibility with engines like fizzy-saas). - Remove sendmail env setup, since by default there is no sendmail in the container, and custom deployment can use whatever config the want directly. If we end up needing this, we can bring it back via its own env.
