Outlook 2003 and Exchange 5.5 firewall problem

[Rollin 4 Eva]

I'm running Outlook 2003 with Exchange 5.5. Our company is small so we
don't have a hardware firewall in place so I have to rely on my Kerio
Winroute Firewall as the line of defense on my machine. Problem is, I don't
know which ports to open up on my computer to allow communication with the
Exchange Server. I know its the firewall, cuz when its disabled, I can
connect to the Exchange Server without any problems. Anybody have any
experience with this? TIA for any help.

This is totally OT, but it doesn't matter if your network is small - you
need a firewall. Your whole network needs to be protected, not just your
workstation. Your company can pick up a cheap little hardware appliance that
will help protect your network for about $120USD....check out the NetGear
FVS318.

smtp is port 25. You might want to consider a Linksys
hardware firewall for under $100 and putting your entire
network behind it.
