2.83  2011-10-29T00:19:07Z
      - Added the `smtp_port` parameter and accompanying `--smtp-port` option.
        Patch from Gustavo Leite de Mendonça Chaves.
      - Switched from Net::SMTP and Net::SMTP_auth to Net::SMTP::TLS, which
        handles TLS and non TLS and auth and non-auth in any combintation.
        Based on patches from Dawood Sangameshwari and Marino Miculan (RT #
        40188).
      - Added `--smtp-tls` option to enable TLS. Based on patch from Marino
        Miculan.
      - Deprecated `--smtp-authtype`, which is now a no-op. Net::SMTP::TLS
        determins the auth type to use by asking the SMTP server.
