Messages received on my Blackberry also come through our ISP and into the server in the office. No problem.
But when I send messages from the Blackberry, copies pile up at the ISP and don't come through to our server, even when I hit "send/receive". That leaves them piling up at the ISP and results in enough space being used up to block other mail. The ISP folks tell me it must be in the Blackberry setup and not something on their end.
Anyone else have this problem?
