Added an MX and Reverse lookup for kyrie to all DNS servers. It looks 
like the info has replicated but I'm still getting bounces. This is the 
error message I get when I try to send to that domain from kyrie

<jjaworski at ccccd.edu>: Host or domain name not found. Name service error for
    name=server87.appriver.com type=A: Host not found
