Determining which email failed.

I have a data driven subscription which delivers multiple reports to
multiple subscribers.
For the most part, it works great.
But, sometimes there is a failure in the delivery.
Ie 10 reports were to be delivered to XXX@.xx.com.
It says that 8 were successful, and 2 failed.
Unfortunately, I cannot seem to determine which of the 10 failed.
This causes me no end of grief, as I cannot know which to resend.
I've tried looking at the log files to no avail.
Is there any way to determine which ones failed?As far as I understand the most straightforward method would be examination
the mail server logs.
Still quite a challenge.
