Drupal System E-Mail

ok, this is probably a dumb question but, here’s the situation. 

I’ve got several sites in development on a Macbook Pro, MAMP system. Most everything works, except for email from the system. For example, if I go to the login page, and I pick the “Reset Password” tab, and I enter my username or password, and I wait a few, and check my e-mail, I’ll get Nothing. If I create a new account, enter my e-mail etc. and it says it’s sending info to my email… nothing comes. EVER. Everything else seems to work, but no e-mail. I’m not sure where to start looking on this one.
