  4. In this section, enter the server’s SMTP address in the SMTP Server field. For instance:, where yourdomain needs to be replaced by your domain name.
  5. Next, go to the SMTP Authentication section and select Basic.
  6. In case you want your emails to be encrypted as well, we suggest enabling the SSL settings.
  7. After that, enter an SMTP username in the SMTP Username field. For instance [email protected]
  8. Enter a SMTP password in the SMPT Password field.
  9. Finally, click Update to save the changes you have made.

Our Support Engineers recommend ensuring that the email address in the Host \Basic Settings\Host section and the email in the SMTP server email address field are the same.

The changes we made earlier apply to all the sites within the DNN installation. We can test this easily by using the Test SMTP Settings button. In other words, this sends out a test email to the SuperUser account and also displays a message indicating the success or failure of the test.
