We have one external email domain that we were able to send emails to before, but now for some reason when we try to send this this one email on exchange 2010, the emails just sit in the queue and just say retry and never get sent out.
If I run nslookup on the external email domain, I get a failure back when running it from the exchange server, but if I run the nslookup from another server or pc, I get the reply back...
There are 2 A records in dns for the external email, so not sure why it just stop sending out emails to it..
Any ideas on what I can check?

Verify your other server / ws uses the same DNS server as the exchange server.  If so open cmd prompt on exchange server and ipconfig /flushdns on it to clear the dns cache.  Try nslookup again

Yes the exchange server is using he same dns as the other servers and I did try the ipconfig /flushdns abut that made no difference.

It had to do with different dns entries.
Not sure why it changed but all is good now.
Thanks
