BuddyPress.org

Buddypress, as mentioned many, many, many times, is wired through the wordpress emails.

Buddypress has absolutely nothing to do with the emails. So don’t blame it on BP, there is nothing bp can do for the activation email really.

As through searching on forums, this issue is rising problems after problem. Bluehost seems to be big with it, so try the “Mail From” plugin.
