New User Activation e-mails not sent

bbPress Version 2.5.14
I setup a bbPress on Saturday on my site. Everything worked just fine with new user activation e-mails being sent. Now, when a new user registers they are not getting the new user activation e-mails to activate their account. I have not edited anything in my settings. Any help would be appreciated.

Note- I have BuddyPress as an active app but not used it. Does this need to be deleted? It was activated befor I activated bbPress. Also, any suggested server settings for the bbPress?
