Well, i have had the same problem and there was nobody to help me out.
I called T-mobile, also Nokia support, but blank.
I spend a little bit time and here we go.
1, u need to set your e-mail addres at t-mobile web site.
2, here is the setting for incoming e-mails for N95 8GB:
messaging/e-mail/options/E-mail settings/connection settings/incoming e-mail
USER NAME: your email address -
something@something.something (killer@nokia.com)
PASSWORD: Enter your password from e-mail address
INCOMING MAIL SERVER: set your POP3 server - mail.something.something (mail.nokia.com)
ACCESS POINT IN USE: set your internet access point - (t-mobile internet)
MAILBOX NAME: Just name for this email client (Killer)
MAILBOX TYPE: POP3

PORT: Default
APOP SECURE LOGIN: Off
For outgoing mail:

MY E-MAIL ADDRESS: your email address -

USER NAME: User mane you created at t-mobile web page like your e-mail address - phone munber:1 (1234567890:1)
