yes i am using SMTP Authentication , but when i m
doing telnet to my server on 25 port so i am able to
send mail by unknow user that in in not my mail server
like
mail from: <abs@xxxxxxxxxx>
this command is showing Sender is ok while its not
user in my mail server.after that
rcpt to: <xyz@xxxxxxxxxx>
DATA
jhsjhdf
.
quit
after this mail is queued for delivery to xyz user and
in this scenario xyz is valid user accound on my mail
server so i want that unkown account for my domain
cant sendmail , so how i will do that ,
when i am sending mail to out side domain without
authentication then everything is ok means any one can
send mail to my domain while he is not user.
this is the problem.
i have one solution , but i want to know very easy
way to do that
