I don't know of any programmatic way to do this - have you spoken to your
firewall administrator? He will need to allow POP3 traffic out to the=20
Internet (at least from the box hosting your app to the POP3 server it is
trying to contact) and back again.

You could also check out SOCKS, which may enable you to proxy through
the firewall.
