 BuddyPress      1.0.1

 Register Plus (this plug-in doesn't even show up when registering) It's
 obviously not MU friendly. But, it isn't causing the trouble as I just
 installed it and the trouble was before this install. I installed this to
 try and solve the problem of not receiving emails.

 ----

 No one is getting the registration emails with the link to click on to
 verify their email address - not even me. This used to work, and now it
 isn't. So, no one is able to sign up unless I "add new user" in the
 backend. Then they receive their emails. So, it can't be my host or those
 emails wouldn't go through. And I'm running out of my own email addresses
 to test this as it prevents the same email address from being used for a
 new user account.

 Has anyone else run into similar issues, and if so, how did you solve it?

 I would appreciate the help. I just launched my site and no one can join.
 Everything works normally, like it takes you to the sign up page, and it
 asks you blog + user name or just user name and send you to the "check
 your email" page, but no email ever gets delivered.
