I am running 4.2.1 and this is the answer to a determined spammer, thank you! HOWEVER, Gmail and AOL (at least) do not receive the code. It does not even make their spam folders. Yahoo, does, but hits the spam folder, which is fine. Other providers like Verizon and others have no problem. What can I do? I Love this, but have found that without these mail services, my join count is down to nothing.
