I created a dummy email page this morning and tested it with the ycdevelopment mail server. I received all emails sent from my test form (which I built using Universal Email, not Security Assist), so there must be something wrong in the security assist page I sent. I've also tried other SMTP servers with my security assist forgotten password page and never receive the email when using any of them (I know there are no access issues with these servers because I use one of them every day).
I'm confused? Can you suggest anything else?
