DotNetNuke Tip: Changing Who Administrator Emails are From
This will be a quick DotNetNuke Tip, but a worthwhile one nonetheless! I've seen this question asked tons of times, and even got an email from someone this weekend asking the very same thing.
"Where do you change the “from” email address for emails sent by dnn to confirm/notify registration?"
That's a somewhat easy one to answer. On the Admin/Site Settings page there is a dropdown box that allows you to choose the Administrator Account for a portal. That account (user) that you choose there is the email address that portal registration emails come from, and most emails from the portal in general. You can have multiple people defined in the Administrators role for a portal, but you can only have one listed here as the administrator.
To change the email address either edit that profile for the user you have selected, or choose a different user!
