Not much you can do. You could try a couple of things:
a) If the bounces are identical or have some wording in common you could
try building a filter, but be sure you are not filtering legit bounces!
b) Consider using SPF (requires adding a TXT record to your DNS zone file,
nothing to do on the Exchange server). This will have limited benefit
because not everyone is using SPF, and if your ANY of your users travel a
lot and uses external services other than the Exchange server to send email
then SPF won't work for you.
