Hi there... I recently moved into my University halls, and since I've connected to thier network, Mail no longer sends messages (but recieves them no problem), and MSN will no longer sign in. All the PCs on the network have no problem using Outlook/MSN, so I'm assuming its down to me? This is happening on a G4 DP on 10.3 and an iBook on 10.2. I have turned my firewall off, why can I still not connect? Thanks!
