    but some mail servers don`t send me AUTH info, but they are use it. Please check it!

      I used RFC 2554 to implement AUTH in jwSMTP for LOGIN,PLAIN only.
      If your mailservers are doing a different kind of login, i.e. not login,plain jwSMTP cannot be used as I have not implemented that kind of AUTH.

  • but now, most smtps need tls AUTH, how can i deal with these smtps?
