I've made sure that my site can send emails and have my site set to verified, yet neither myself, nor the end user is getting registration emails.

Thoughts? Am I missing a setting in a config file somewhere?

Yes, and it sends successfully.

you could try adding a file based pickup to see if the email is rendered i.e. if the code works but the mail server is not sending the mail (perhaps the user's email is invalid, or the domain not allowed in the SMTP server)

edit your web.config and add something like this just before the final </configuration> tag (change the pickupDirectoryLocation location to the folder of your website). You can then see if the eml files are generated - if they are then the issue is with the mail server

  <system.net>

    <mailSettings>

      <smtp deliveryMethod="SpecifiedPickupDirectory">

        <specifiedPickupDirectory pickupDirectoryLocation="C:\Github\DNNS\Website\" />

      </smtp>

    </mailSettings>

  </system.net>
