Sending E-Mails in Visual Basic 2010 Express

Mar 2 2011 3:07 PM

I'm making an application that allows you to send an e-mail to the e-mail that is entered in a textbox, my code is in the attached file.
But it gives me errors, so I think it is the smtp and port number, does anyone know what the smtp and port is for hotmail.com and hotmail.co.uk and the smtp and port for yahoo.com and yahoo.co.uk.

Thanks
