With regards to your question, i feel you are indicating configuring your Bellsouth account with your Outlook express since it is a platform to check emails on multiple accounts. Bellsouth is a part of AT&T and is powered by Yahoo. In case of your bellsouth account which is essentially a yahoo account, you would need a premium account signed up with Yahoo only after which they give permission to set up POP accounts and only after which you can transfer your contacts to Outlook express.
Kindly revert for further clarifications,
Thanks and regards,
