Not getting notification e-mail in case of time based publication

Hi,

We are working with subscription service.

We have one document subscribed by some users.

Users are getting notification mail whenever there is any modification in that particular document.

But when I am setting the lifetime property of the document.

Users are not getting notification e-mail when that document get published or get expired.

We checked in the Subscription Service.In the Allowed Admin Notification field we have to mention the proper event.

But we don't know which event name to mention.

It will be very helpful if any one let me know about it.

We are using EP 7.0.

Regards,

Biswarup
