Hi,

I've got the Blackberry professional server installed. The blackberry is receiving all emails when its connected wirelessly to the network. When I connect on 3G emails cannot be sent or received. Port 3101 is open on the firewall as requested on the blackberry documentation.

I did an ethereal scan I see some chatter on port 3101 between the server and IP 206.51.26.124 - that IP resolves to some blackberry infrastructure.

I also see a lot of chatter with blackberry ip and server but on port 4101.

Everything seems to be setup correctly but obviously its not. Any idea's

Your phone hasn't been provisioned properly.

Look at this post for a nice tool to help you test it.
