c# software to signup yahoo.co.uk email accs. and set pop3

Small software needed to create and setup yahoo accounts to use pop3 - must be [login to view URL] (or any other country account that allows pop3 with free email account). 1. User enter no of accounts, clicks Generate 2. Random account details pulled from dbase(I have one) 3. Software will then signup those accounts, and store the pass/login details to a .txt file Ready made and commented code is good, as will most likely add to an exisitng tool.
