Hmm... I guess it's not universal. I've got some places that can't see
anything, but others that can. The places that can't get messages like:

*** umbc3.umbc.edu can't find aip.acp.org: Non-existent host/domain

Here's my domain file for it:

$TTL    3600
@               IN      SOA     exeter.acp.org. postmaster.acp.org. (
                                1999111601
                                3600
                                300
                                3600000
                                1800 )
                IN      NS      exeter.acp.org.
                IN      NS      defiant.acp.org.
                IN      MX      10 acpgate.acp.org.
                IN      MX      50 exeter.acp.org.
                IN      MX      50 defiant.acp.org.
                IN      A       149.28.226.101

$ORIGIN aip.acp.org.
acpgate         IN      A       149.28.226.101

Thanks again!
