Switch user :NOPASSWD setting

Hi All,

I want trigger a script "abhishektest.sh "whenever a mail come to a user say "abhishek" in my unix server. I dont have root permission.
So, for doing this
i added abhishek : "|/export/abhishek/bin/wr_test.sh in /etc/mail/aliases

in wr_test file : i need to put this line, as i have to switch user from root to abhishek.

[LEFT]/usr/local/bin/sudo -u abhsihek /export/abhishek/bin/abhishektest.sh

Can You please tell me which command need to put as NOPASSWD rule and what should be exact syntex for NOPASSWD rule? and where should i put this command so that sudo will not ask for password.

right now ,without sudo settings it is giving this error:
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
Password:
Sorry, try again.
Password:
Sorry, try again.
Password:
Sorry, try again.
sudo: 3 incorrect password attempts

Please help me out.
