I assumed that Internal user send email to one of External domain at time user got this NDR,

check by send email using telnet to that remote domain, you should get more info on this.
http://www.rdpslides.com/webresources/FAQ00035_Send_Email_via_Telnet.htm

enable SMTP log ans send once again a email, once you receive the NDR, attach report to analyse the same.

I'm going to assume that it's because the SPF record for yourdomain.com contains the instruction "include:yourdomain.com". That is not valid, and it seems like the recipient domain is refusing email that has invalid SPF records.  Could you post your SPF record from public DNS?
