Migs' right. In addition, I have a topo here.
Here's a simple solution:
1. The FW has an open port on 22 but not port 110
2. There's a linux box running openssh
3. There's an exchange server which has pop3 enabled
4. A client on the internet has a Tera Term with SSH support installed on
his windoze.
He connects to the ssh server. It has Port Forwarding setup locally which
points to the
Exchange server.
5. The windoze box also has a pop3 client which he uses to connect to his
local machine
via the port he specified on his Tera Term.
6. Transactions are passed thru port 22. Could be DES, 3DES and so on and so
forth.
