auth people by email or flat file

[Jean-Francois Brison]

Hi all,

Is there any way to authenticate people by their email addresses so that
only articles coming from specific email addresses are allowed to post?
And what about the readers.conf file I read everywhere about?  In which
release is it included and is it considered as stable?

Another question: I have read about the ability to read
username/password from system files (ie etc/passwd).  Is there any way
to read password from another flat file in the same format (e.g. in the
same format as .htpasswd)?

Thanks for your time.
