MX problem or not?

We are trying to bring up our secondary NS box as a
backup mail server in the event that our Primary
NS/Mail
server goes down. The Primary server is running
Sendmail 8.8.7 with aliases that point to our internal
localmail
server. Whenever we shut off smtp on our Primary mail
server the Secondary starts getting mail sent to it.
The
Secondary server is running Sendmail 8.10.1. The
problem is that when the Secondary recieves mail
destined for
user at domain.k12.state.us, it attempts to relay it back
to the Primary server. If we send a message to
ns2.domain.k12.state.us, the mail goes through just
fine. I think my domain file is fine but, it may need
a little
tweaking perhaps? Or, is this a sendmail settings
error? I have the domain as well as ns1 and ns2
listed in my
sendmail.cw file... Any help would be great.
