Recently I installed joomla 1.7 on my zymic site and i went to the joomla admin panel to change the Mail Settings, I knew that zymic don't have php mail function for free and therefore I changed to something like this to make my gmail send out email(outgoing):

However when I setup my joomla new user registration function, and I tested this function by try registering a new account on my joomla site. I have got these errors:
SMTP Error! Could not connect to SMTP host.
Registration failed: An error was encountered while sending the registration email. A message has been sent to the administrator of this site.
Anyone know the solution to this issue? I have been googling around but I got no answer. And I'm sure that my gmail address and password are correct.
Thanks a lot!
