Users may want to send a new user registration email from a different portal from the site that the user registered from.
- SMTP Server enabled on the site you are authenticating from.
- Registration Type needs to be set to Private.
This feature cannot be accomplished through out-of-the-box functionality, this feature has been submitted as an enhancement to include this feature in a future release of DNN.
To accomplish this you will need to create your own third-party module using SMTP API that takes the information that the user will submit in a user registration form in Site B and use that information to create a user in Site A.
Once the user registers from Site B, they should be able to receive an email to confirm their registration to Site A.
