    yousaf@dwp.com.pk isn't an e-mail address that the receiving system
    recognizes.

    The problem could be something as simple as you entering an incorrect
    e-mail address. Here's a simple test:

    telnet mx1.dwp.com.pk 25
    220 mx1.dwp.com.pk SMTP Server (Secure Mail Matrix 4.0 Build: 4.1.1.1
    ) ready Mon, 25 Jan 2010 16:11:22 +0000 (GMT)
    helo XXXXX.com
    250 mx1.dwp.com.pk Hello XXXXX.com ( [66.XX.XX.XX])
    mail from:<rich@XXXXX.com>
    250 2.1.0 Sender <rich@XXXXX.com> OK
    rcpt to:<yousaf@dwp.com.pk>
