calcat,

I had the same problem first time I configured a bizform to send email. I got the error re failure sending email, though the re-direct worked, and the form data was saved (I could see the data in Bizforms | <form-name> | Data tab).

After some research, my problem was related to Relay restrictions within the SMTP service of Internet Information Services (IIS). This problem arose on my development PC, not on a live server (as I haven’t got that far yet - maybe the next few days). I’m running the site locally on IIS (a Windows service), so the run the site I enter http://localhost/ in the browser. You may be using a different arrangement.

To solve the problem:
Open the IIS manager (via Control Panel | Administrative Tools).
In IIS manager, expand <computer-name> (local computer) in the left-hand pane.
You should now see Default SMTP Virtual Server.
Right-click on it, and select Properties.
In the Properties window, click the Access tab. Click the Relay button. In the Relay Restrictions window, I have the option ‘Only the list below’ selected. To add ‘localhost’ (IP address 127.0.0.1) to the list, click Add, select Single Computer, enter 127.0.0.1, then click OK. In the list, you should now see access is granted to localhost. The option ‘Only the list below’ should be selected. Click OK, and OK again.

I don’t recall if I had to re-boot, but now the SMTP service successfully processed email messages from my Kentico site. (I’m still using my own email address for testing, so I get near immediate feedback.)

The second part of your email describes another problem. I sugest you return to your original settings, then try to fix the original problem first, as described above.

Hope this helps you,

James
