Invalidate an email address

Hi all,

I am trying to invalidate an alternative email address of contacts (email_alt1). 

For this, I tried following codes and none of them worked.

$contact->email_alt1_invalid=1;

and

$contact->Emails[$emailIndex]->Invalid = true; 

what am I missing here? What is the right way of invalidating an email address?

Thanks

Bishnu
