Seems like you're having problems with your network connection, possibly dropped packets. A 451 error is returned by the server when it did not get information from you quickly enough. "read error from such and such" probably means that Sendmail didn't get the expected response from the server, or that the response was garbled.

it is problem from my side or from the other party side, becoz i tried using postfix from my other server and get the same problem too. so i think it is not a MTA problem

POSTFIX SAID : (connection reset by mx.abc.net) while sending DATA command

It seem that postfix get the problem while sending the DATA comand to other party server and the server dropped the connection.

is the problem lie with my server or what?

only 5 email that my server cannot sent out, the others is okay.

Anybody can help me?
