How do the email-related access control settings work?
Under 'access control settings' I have the option for 'Require valid email for' set to 'nothing - not required' as opposed to 'account registration'
As well, under 'access control settings' I have the option for 'Blacklisted email address patterns mode' set to 'block completely'
Yet, when I try to sign up with any email address I get a message that the email address is not allowed.
I have double checked to make sure that the email addresses I was signing up with were not on the blacklist.
Is there documentation somewhere that describes how to use these features and by what parameters they operate?
