What is the domain name for your mail server? If there's a problem, you
can verify by checking the MX record (dig MX), .. you might also want to
verify that your reverse DNS is configured properly (dig -x ).

If it's usi.edu, you have the following MX records defined:

;; ANSWER SECTION:
usi.edu.                86400   IN      MX      3 ninja.usi.edu.
usi.edu.                86400   IN      MX      3 ninja2.usi.edu.
usi.edu.                86400   IN      MX      30 adams.ind.net.
usi.edu.                86400   IN      MX      30 washington.ind.net.

ninja is OK:
ninja.usi.edu.          86344   IN      A       192.206.10.123

also reverse:
123.10.206.192.in-addr.arpa. 86400 IN   PTR     ninja.usi.edu.

ninja2.usi.edu.         86291   IN      A       192.206.10.124
124.10.206.192.in-addr.arpa. 86400 IN   PTR     ninja2.usi.edu.

adams.ind.net.          21912   IN      A       157.91.1.9
9.1.91.157.in-addr.arpa. 604800 IN      PTR     adams.ind.net.

washington.ind.net.     21879   IN      A       157.91.1.1
1.1.91.157.in-addr.arpa. 604800 IN      PTR     washington.ind.net.

usi.edu seems to check out.
