Hello,

I'm getting this error "Mailbox unavailable. The server response was: Authentication is required for relay" when sending de CC message from then form. It seems as if Form Master is not using SMTP authentication data for sending that mail (these data are correctly set in host configuration). Form Master 1.5 + DNN 4.8.0.
Anyone can help?

Thanks,
Francisco
