if you require activation then you should show message for those users. Say they sign up but they are a member of the Users Awaiting Email Confirmation
which is usergroup 3.
Basically put something in your templates, maybe in the header a banner for that usergroup only. Tell them they need to activate their damn email first and to check the check or bulk folder.
this may help
