Hi,

Can anyone help me? I'd like to change the email address to which notifications are sent when a new user registers using Community Builder.

I've tried changing the email in Configuration > Registration > Registration Reply to Email Address, but this doesn't seem to work.

I'm sure it's simple but I can't spot it! Any suggestions?

The reply-to Email is just the visible sender adress. This adress is visible to the user receiving your email.
This can be a fake email like NO-REPLY@YOURDOMAIN.COM

The parameter above is your real sending adress. Tip: Use a valid adress... your hosting environment may require a valid, physical email account. It may not work with an email ALIAS.

There are more parameters, that influence system emails. Did you check your Joomla user accounts:

-> user manager -> yourUser -> receive system emails YES/NO

-> CB global config -> Moderation tab -> Moderator group... (if you have multiple admins or managers, you should set your group accordingly)
