No Contact Forms are Sending E-mails

I’m using WP version 2.7.1 and I’m not sure why but I’ve tested a lot of the compatible contact forms and though they do give the ‘Sucesss’ message after I fill out the form, I never receive the e-mail. I’ve used yahoo, and google; I’ve checked the spam boxes and nothing. I’ve tested Contact Form 7, DD Form Mailer, WP-ContactForm, CleanContact, and many more.
