One last thing some miss (or rather don't miss but should do) is the "Log on using secure authentication" box as this should NOT be checked when setting up NTL mail account.
The secure log on is only required for setting up accounts like hotmail in outlook/outlook express.
N.B. Also remember that passwords are case sensitive so it is easy to miss the caps lock key being on when typing or re-typing the password as all you see is ***********.
