i intend to set up a lotto business and internet cafe.

in business?

I can send/receive using gmail in outlook without a problem but I cannot send using my other address. All of the settings have been double checked with my ISP and business email server provider and still no luck. This is driving me nuts. Is it my PC blocking the connection. I am running Vista and i use AVG as my security. It seems to work initially and then just stops as if the connection times out or something. Any help would be appreciated?
