Hey, I have DNN 7.2.0 setup on my local machine and I can get the SMTP email to work no problem... I then setup DNN 7.2.1 (latest) on my webserver, but every time I enter anything in for the SMTP settings and press Test I get this error on the top:

There has been an error trying to send the test email. The error is:
There is a problem with the configuration of your SMTP Server. Mail was not sent.

and this in the log:

No matter if I try and internal or external SMTP address, or the same as I had setup on the local machine, I cannot get it to work... I know my web server can send email because there is a form on a different website that works fine... I tried using the smtp info on this .aspx.vb page and it sends fine. I just cannot get it working in DNN... Any ideas???
