Dear All, I want to ask a simple question regarding smtp authentication. (Assuming that the user is not in my trusted networks) If smtp authentication is on & the client connects through a EHLO session, then the authentication goes fine and the user is authenticated, but if he connects through a simple HELO session, then he is able to send a mail without any authentication? How can i disable the HELO command or basically only allow EHLO sessions?
Thanks in advance!
