There is no email problem when I use WP only. But,if I install BP,some new registered users can not receive confirmation email.
My email system was offered by my web hoster with the name firstname.lastname@example.org. Most Yahoo or Gmail users could get the registration email immediately,but, the PAID-email users didn’t. It’s odd!
There must be a solution for BP mailing. It’s really not a very good idea to solve any problems by using substituted plugins…..
