Use Senuke, make sure to configure the pop server.
really? i thought se**n*e can only confirm for the 2.0 websites it can register on.
Register anything you would like but keep in mind that you will have to check the spam folder and confirm emails that went to that folder manually since senuke checks only the main email folder . I have attached a pic of the email verification screen.
I am going to jump in here you are using yahoo? Am I wrong when you want to access pop via yahoo you have to be a paid subscriber. Try making another email with a different company and forwarding off your emails to the new company/email addy then use the tool that you have and use the auto confirm thingy you got with out the yahoo error as pop not allowed because I think you need to be a paid member to access that feature.
I hope this makes sense it did in my mind.
