I'm not sure how useful it will be anyway, with all the large providers 
making filtering decisions based on individual recipient's behaviour.

You can certainly get a rough idea of what is going on, but all of the 
past mail sent to the aforementioned test account and the way the "user" 
acts toward that (or doesn't) will impact future deliverability to that 
one mailbox in a way that may not reflect on other mailboxes.
