where are you telnetting from? localhost?
telnet localhost 25?
mail from: <abs@xxxxxxxxxx>
this command is showing Sender is ok while its not
user in my mail server.after that
if you are using delayed checks, this is normal. BTW, does this sendmail
box solely does smtp-auth relay only? It is not used for receiving mail
right?
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.
Okay, I thought you wanted something like that. You want to allow only
mails where the sender exists on your system, right?
i have one solution , but i want to know very easy
way to do that
.
well...you could try looking for ready made rulesets for what you want.
Otherwise, it will have to be written.

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?
