Mailing List Form Script

Search Yahoo Address Book?
I need to develop an application to send emails to read some form a Yahoo address book. For the user must enter a valid e-mail address and password of the account (password not stored or used for illegal purposes). The script would have to bring your address book to the account and the list of all contacts, so the drive can select Send an e-mail. Since the application must be 100% legal, I would like to know if there is a solution for this problem and if the execution of these operations is not banned by Yahoo? I do not know how familiar with these things, but there are many commercial scripts doing this you can even find one in Hi5 and Ringo. Is it possible, but I whether there is a legal backgorund this. Thank you
It is not possible. You can not access someone has a script.
