sir Takayuki Miyoshi, do you have any clue what could be the issue? I don’t receive the mail in my spamfolder, they never arrived, although in the frontend it said: message sent succesful. It seems many people suffer from this since WP3.2 & CF 2.4.6
I tried with 4 different emailproviders and my own domain, which I control the spam of. It just never arrives. I tried with using single email & multiple emails…always the same result: “sent succesful”, yet never received.
