What type of firewall do you have?  Windows firewall or something else?  Are you using an email service or your own SMTP?  Are you asking how to setup SMTP sending in Outlook?

We have a WatchGuard X700 running Fireware 8.3, behind that is a Exchange 2003 SP2 box.  I am trying to configure this box/firewall so I may access my Email via a pocket pc using POP3.

You will need to open ports 25 and 110 on the firewall, at least to the mail server.  You then to to configure Exchange to run POP3(if you have not done this already).  If not, it's pretty easy to do.

Check and check.  Where I am running into problems is how to configure the outgoing  server propertieson the client machine.

The outgoing server will be the public IP Address or public name of your mail server.   You will probably need to make sure the "My Server Requires Authentication" box is checked.  How do you currently have this setup?

I did that, but I keep getting a connection error.   The receive side of things with POP3 works fine, just the SMTP send.

Funny enough it works on the pocket pc phone just fine.  I was testing with Mozilla which was not.  Oh well.  Works for me.
