Setting up email with 6600 and T-mobile?

Hi,

I'm trying to configure my phone to check email, and am unclear on a few
things:
1. My goal is to configure the phone to check my comcast pop email
account. I currently have the lowest level of t-zones, the $4.95 a
month plan which I believe gives me email access?
I also have an Earthlink account, but haven't been able to configure
things successfully with either t-zones or Earthlink.
When I configured theEarthlink access point, I selected data call as my
data bearer. Everything else in the connection settings seemed pretty
standard; However, when I tried to Check email with my mailbox set to
use Earthlink as the default access point, the phone attempted to
connect and then after a few moments, gave me a "call not allowed"
message.


I tried setting the mailbox default access point to t-zones. When I do
this, the phone prompts me that a connection to the server is needed.
It appears to connect to the server and doesn't give me any error
messages, but it never pulls email from my comcast account.

I must be missing something here? Is it possible to do this with the
plan I currently have? If so, what's the secret?

Thanks,
