  # HACK AHEAD! Here's why:
  # 1. FarmBot Inc. Uses Sendgrid for email.
  # 2. FarmBot is an open source project that must be vendor neutral.
  # 3. Heroku uses non-neutral ENV names like "SENDGRID_PASSWORD"
  # SOLUTION: Support neutral names like "SMTP_HOST",
  #           but fallback to non-neutral var names like "SENDGRID_USERNAME" if
  #           required.
