Symantec DLP - Blocked EMail notification

Dear Experts,

We are facing while creating blocking SMTP email rule. I have created rule like below.

//

An e-mail sent by $SENDER$, regarding "$SUBJECT$" was blocked from going to $RECIPIENTS$ because it violated the company's $POLICY$ Policy.

//

Now, End user is complianing that in $RECEIPIENTS$ list, he is getting all mail addresses. He want to know specifically which mail ID got blocked.

He use 4 to 5 mail IDs in "$RECEIPIENTS$" whereas mail will be blocked for 2 or 3.

Kindly let me know if there is any option to change the value.

Thanks in Advance

Siva
