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@domain.com
this command is showing Sender is ok while its not user in my mail server.after that
rcpt to: xyz@domain.com 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 .

Did you use AUTH to authenticate yourself?
Also, from what you say, do you also want to make sure that any user who authenticates must use an email address in your domain as their return-path? _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
