Dear all,
I've a Nokia 5800, s60v5. I'm trying profimail and it's great but I have a little problem. I use Wifi to check email and I would like to check it every 2 minutes. It works well, but I would like Profimail to: connect automatically (ok) - check email and play a sound if there are new messages (ok) - automatically disconnect. Unfortunately, unless I unchecked "Keep connection", the connection still remains active. Is there a way to force disconnection after mail check?
Thank you!
