How to Send Bounce Backs to Users Awaiting Validation?

[420]

When i do an email newsletter to my 100,000 members, i get about 10,000 bounce backs... then after a few times of the same bounce backs, i begin getting deferred by yahoo, att, charter, excite, pacbell, earthlink and many more... then i have to sift through the 10,000 bounce backs, find the deferred ones and submit unblock requests to each isp that has blocked us... is it possible to send those bounce back members to the Users Awaiting Validation usergroup, so they will stop bouncing back next time?

If you only send to Registered Users, the bounce back issue is solved, with this idea/solution, right?...

Thanks for your valuable time.
