We are running Exchange 5.5, it seems that out Outbound queue is filling
with NDR's with a invalid return address. We are getting several
thousand per day. Any recommendations to get this reduced? What are
other admins doing to fight similar problems?


In today's day and age with the massive dictionary attacks and bad lists
from spammers, plus the Outlook virus's you must have a system that
checks for valid address during the initiation connection. Then at that
point it 5xx's the connection  so you do not generate the NDR's. The
sending server is then responsible for the NDR to the original sender.

Don't think 5.5 will do that. It is time to get away from 5.5, imho.
