Stale DNS Entries

[ekwstats]

I have a few domains that I can no longer send emails to because they changed their DNS records and for some reason my DNS server is not seeing the changes and therefore is trying to resolve to the old IP.
I have tried the flushdns, remove stale records, etc with no luck.
My mail server is using two internal AD DNS servers for primary and secondard DNS and both of those servers are still resolving to the old IP.
So, my question is how can I determine if my DNS is set up right so that I don't get stale records or how can I force the DNS to update?
Thanks

You need to clear the cache for those domains on your DNS server.
