You have asked this question before:
Normally you can collect e-mails from your earlier e-mail addresses by configuring each address's ISP POP3 and SMTP details in Accounts - collection is via your own ISP from the Connection tab's menu (i.e. use your current ISP's listing or LAN).
However, if you wish to Send e-mails it has to be using an AOL e-mail address.
That's why, if your daughter receives an e-mail using her OneTel address, if she Replies to it she will have to use the From: drop down menu on the Message panel to change it to her AOL e-mail address.
