you have set the success redirect to go to the login page, are you redirected to the login page, or does it stay on the email password page?
If it is directing to the login page it is trying to send the email.
You mat want to try leaving the smtp server and port settings blank.
also try leaving the from Name blank and only supplying the from address.
If it is still not sending the email, check with the host to see if they can look into the SMTP servers error logs to determine why the email is not being relayed by the smtp server.
