I believe I'm right in saying you've had this problem for a while now; I
seem to remember talking to you a while back.
Telnetting to mail.okcca.net externally (from my server 18.104.22.168)
port 25 (SMTP) works fine:
telnet mail.okcca.net 25
Connected to mail.okcca.net.
Escape character is '^]'.
220 Welcome to Qmail Toaster Ver. 1.3 smtp Server ESMTP
However, you cannot connect to the POP3 port on this server:
telnet mail.okcca.net 110
telnet: connect to address 22.214.171.124: No route to host
This is the error usually seen when a firewall either on that box itself
or an intermediate router blocks the port.
Now, internally this may be a different story.
However, judging by what you're saying (the e-mail account in question
resides on your Exchange 2003 server) - you need to be connecting to
that machine, not mail.okcca.net.
The IP address of your Exchange 2003 is a private LAN address - that is,
not publicly accessible/routeable from the Net, therefore your phone
will probably need some kind of VPN into your own network to get to that
server (whereas if your laptop is already on your internal network, this
won't be a problem.)
I think you need to clarify where your machines sit in relation to your
private and public-facing networks, and how your phone connects (i.e.
what IP address it gets assigned and where from.) Try browsing to
www.whatismyip.com on your phone to see what IP address it has been
given - whether it's assigned by your own network or the mobile provider

Does Exchange 2003 where the mailbox is, face the public Internet? If
not, your phone will need some sort of route into your private network
space (such as VPN.)

Does your qmailtoaster machine run a POP3 service? If so, a firewall or
router is blocking external access to port 110.
