Asha 30/40 Series :: Setup 8800 Carbon Arte To Get Email Automatically?

I am trying to set up my Nokia 8800 Carbon Arte to get my email automatically. I set up the mailbox and automatic retrieval but unfortunately the phone will not retrieve emails unless it is manually connected to mailbox and when it is it drops connection every 20-35 minutes. I have the mailbox update interval set to 6 hours but it won't retrieve them unless the connection to mailbox is active. Am I able to use this phone to get my email as on iPhone managing the connection itself?
