Buddypress does not send activation email

I'm trying to get BuddyPress up on running. This is a new Wordpress install on Godaddy.com, as my previous EC2 is showing problems (I will hire a developer to make it right).
Activation Email (when registering a new user) is not being sent.
Observations:
* I used "Easy WP mail" and "Mail From". Test email works!!! Real email did not.
* I disabled all plugins except BP and WPMU dev. Didn't work.

Can you help?
Thanks.
