Well the error by hotmail wasn't very descriptive...
But check this:
C:\WINNT>nslookup
Default Server: UnKnown
Address: 10.0.0.1
> set type=MX
> eastran.com
Server: UnKnown
Address: 10.0.0.1
*** UnKnown can't find eastran.com: Non-existent domain
>
Check that your external DNS servers are operating properly...
