I just installed Dotnetnuke 5.2 on a new domain.  I setup the SMTP and hit the test link and get email sent.

When I try and register a new account I get the following message "There was an error sending confirmation emails - There is a problem with the configuration of your SMTP Server. Mail was not sent.. However, your user account was created successfully."

When I do a newsletter it send out the email with no error.

Thanks

Joe
