Well, is 126.96.36.199 the correct address for mail.occa.state.ok.us or
isn't it? That's what DNS is returning. If it's correct, then this
isn't a DNS problem.
When I try to connect to port 110 on that address, I never get a
response. This generally means one of these problems: 1) the server
with that address is down; 2) the server is disconnected from the
network; or 3) there's a firewall or filtering router blocking POP
connections to the server.
It doesn't look like #1 or #2, because I can ping the address. Also, I
can connect to the web server on this address, too. I see the same web
page as when I go to www.occa.state.ok.us, although that address
resolves to 188.8.131.52.
I suggest you investigate firewall problems.
