In mid June this year we changed our name servers and updated our server. We receive mail from most of our clients yet there are a handful that we never receive anything from. They do not get ndr's. I had them flush their dns but that did not help. Any suggestions would be appreciated. Thanks.

not receiving mail from all clients

Did you run your own name servers or did you use a hosting company?
If you had a hosting company, then verify they actaully deleted your zones and not just make then inactive.
I had the same issue when we "in-sourced" our DNS. Clients that used the same provider couldn't e-mail us because the provider's DNS servers still claimed to be authority for the domain.
Have the client perform a NSLOOKUP on your MX and A records.
